Hoping my viewers from this channel can join in for next month as well. It's good practice as you get to download the RAW stacked SeeStar image and process along with me.

Does this work for Mac as well?
Hi. It will work just as well with a Mac :) I have started putting in some hints about how some shortcuts are different on Mac than Windows in my newer SeeStar video Series here: th-cam.com/video/WqNxzFmjRZ4/w-d-xo.htmlsi=IJrif0VR50IB-fpr
Wow!!! An incredible difference. Thanks Abdur for the tutorial - works perfectly. Just StarX'd a mosaic. 25 secs vs 15 mins!
Thank you for this. This approach works better than the seestar script for me. Thanks for posting
Thank you. I didn't see anyone else taking advantage of the drizzle integration option so I made this tutorial. Using drizzle X2 as I do in this video really helps with the SeeStar :)
Secondary is not centered 👍decolimated try it again.
Rst135e from rainbow Astro. 0.5kg lighter. Higher capacity. Renishaw encoder. This is “ultimate”. 😊
The only issue I see with the S50 is the field rotation caused by its alt-az configuration.
Excellent tutorial, Abdur! One of the best I have seen on Siril!!
Thank you! Glad it was helpful :)
Hi - what add-on tracker mechanisms would you recommend for this telescope?
Hi. Unfortunately it doesn't have the capability to add tracking. For anyone interested in astrophotography (with tracking) I recommend the SeeStar S50 instead. It is the best deal for the price. I reviewed it here: th-cam.com/video/GrCPD2gx5Ok/w-d-xo.htmlsi=ElB83L1ZFb-C8rAi
@@AbdurAstro much appreciated!
My S50 is on the way , can't wait to produce some of these myself
Awesome! You'll love it :)
It’s amazing for deep sky imaging. I keep my C8 for visual on the moon and jupiter/saturn since that’s very special to see visually - but yeah I sold all my astro crap and haven’t looked back. 7 pounds and $450 replaced $2000
Thank you 👍
Thanks for the list. That 3D printed dew shield is printed horrrribly though. You need to get a refund if you purchased it.
Hi there. I found the print quality to be very good. Do you have one and what was the issue you found with it?
@@AbdurAstro 2:00 - I'm seeing a ton of Z-banding which is indicative of loose belts. It can cause structural failure later on in the print's life. Not a huge issue for this particular application, but I 3D print a lot and I would not deem that as an acceptable print to send a client.
Thank you. I'm a commercial photographer and wanted to dip my toe into Astro, so I bought a SeeStar. I'm not interested in dropping loads of cash into this hobby. Your comparison is very educational. Thanks.
Hey it's Trevor from RASC! Excellent video, my Seestar images went from pretty neat to: whoah! Very helpful and informative, easy to follow along and well spoken 👏👏👏
Thank you Trevor! Glad it was helpful :)
Nice
Never spent this much on a scope before. Most expensive one I have is an AD8. I'm seriously trying to talk myself into this scope now.
Love the idea of comparing the three cameras. I have a Seestar and use 10 times more than my Celestron SE8. Mainly because it is so easy and fast to set up anywhere. The Seestar has the highest "bang to buck" ratio of any telescope or camera I've ever purchased.
Excellent tutorial. Thanks.
Thanks for watching! :)
I have the 3. Just spend the extra 200 bucks on the 5. Trust me.
We trust you 😉. But why go with the 5 instead?
Ive always wondered whether or not this would be possible using an amatuer telescope and i hope thet you succeed, good luck and godspeed🌠🔭🫡
Chromatic aberration? More like chromatic abhorration. The daytime images looked like a rainbow. Your video is fine but this thing is a piece of junk.
Excellent tutorial, however, is the post-processed picture better? It's difficult to tell as they are not cropped the same? It's certainly a different colour - whether that's good or bad I'm not sure? I am going to try some post-processing but have to say I'm blown away by the results straight out of the seestar. Also, I've seen some people's pictures that have been run through up to 10 different apps and, to me, looks like they've either lost a lot of integrity, or totally over-cooked the colours? Anyway, I thank you very much for your clear and detailed guide.
Hi. The post processed picture has a resolution of 3840x2160 while the original image had a resolution of 1920x1080. I used drizzle integration (that's why I modified the script) to increase resolution. That is why the processed picture looks bigger even though they are both cropped at 100%. The SeeStar is an amazing tool but you can definitely improve the results by processing on a computer. I only used one app in this case (SIRIL).
Tks🤟🏼🖖🏼
I have watched several videos on the subject and this is the best one nice one😊
Pixel size of Canon 6D (6.54) is more than double of S50 (2.9) and more than ASI2600 (3.76). So, maybe the biggest difference in resolution is because of that. Also Canon 6D is very old, 2012. TBH I would really like to see your comparison with a modern mirrorless, as Nizon Z6II, Canon R6, Sony A7V, etc.
I have this... # Align lights register pp_light -2pass seqapplyreg pp_light -filter-round=2.5k and I don't seem to work around it without an error It's a newer version I suspect
Of course it can't compete with an 8in Dobsonian.
I agree. But it is MUCH more portable than an 8" dob so each has their advantages.
That’s some significant vignette. What size sensor are you using? Are you using a 1.25 or 2 inch?
I am using an APSC sensor (ASI2600MC DUO) and I was using the 2" filter (this one doesn't come in 1.25"). The vignetting isn't too bad but looks worse than it is due to autostretch. Once flats are applied it completely corrects the vignetting. The vignetting was very likely being caused because I was using an M48 imaging train for this test and the filter was a bit far away from the sensor. That doesn't affect the results I was testing for at all however I have since switched the imaging train to M54 to further eliminate any vignetting.
Im thinking about getting this eyepiece for my heritage 130p, I do have a couple of concerns though. Do you think it would be a good choice? Also, has anyone ever told you that your voice is extremely soothing, i love your accent.
Thank you so much. I am often a bit insecure about my accent when I am making videos so I am happy to hear it isn't too much of an issue. I think it would be a fine choice for the Heritage 130 if you need a small and light eyepiece and if you are interested in higher magnifications. I often carry my entire eyepiece kit with me but if I was travelling, I would take this eyepiece without any concerns. I would likely also take one low power eyepiece (something like a 31 or 32mm) for really large targets like the Andromeda galaxy.
@@AbdurAstro also, do you have any recommendations for a 2x barlow for under 45$? Or do they not make them that cheap
@@cucumber_sandwich4562 For $40 I would recommend this barlow: bit.ly/3SbYX0N I have used this one in the past and it performs very well. I now use an Televue 2.5X Powermate which is a lot more expensive but the difference visually won't be very noticeable in the Heritage 130p. I mainly got the Powermate for high resolution planetary imaging. Next one up from that would be this one but it's $99: bit.ly/4d2wEdd Again the difference won't be very noticeable unless you are using some high end eyepieces in good seeing.
@@AbdurAstro thank you so much! It makes me a lot more hopeful when someone experienced tells me personally that something is good instead of just people in a video!
@@cucumber_sandwich4562 My pleasure. Reach out anytime if you have any other questions :)

I love my SeeStar. I was just doing some imaging tonight. I still can't believe it comes with all of these features for under $500 (I didn't even have to pay tax or shipping!). I live in a mid-sized, light-polluted city, but I can capture the Sun and Moon and nebula and galaxies. I love it!
I totally agree. The SeeStar might be the best value in astrophotography for beginners right now. I estimated it would cost me $2300 to put together a setup with all of the same features individually.
That was a nice comparison. Thank you. I have a Seestar that arrived last December. I'm in my 60s and on a pension, so cost is a concern. Astronomy is a deep interest, and I do have a telescope, but my arthritis, lack of skill, and living in a light-polluted area make it very difficult to use. While I love astronomy, I have too many interests to devote enough time to learn how to use a telescope properly. My Seestar is a total joy. I can set it up, turn it on, and then sit back and see wonderful things. While I can only see a handful of stars in my area, I get amazed at the things that show up from my SeeStar. The other night I saw the Dumbbell Nebula for the first time and was amazed and thrilled. I'm regularly checking out the Sun for sunspot activity. I can't wait to see what these devices will be like in 10 years.
I'm right there with you my friend. It's an exciting time to be getting into astrophotography. Things are so much more accessible than they used to be. Being able to see color in nebular in near real time is absolutely amazing. I am tracking sunspots with me SeeStar as we speak. The Sun is quite active right now.
Count down timer on the app is a good idea, but does it not throw any low battery 🪫 alerts? I haven’t run it down to that level yet.
It has the option to automatically shut down when the battery gets low. However for really long imaging sessions, I use a USB power bank to power the SeeStar. In that case it keeps running and doesn't automatically shut down.
Very Helpful! thanks
Thanks for watching.
How’s the mini filter wheel in the light path when using the hyperstar? Amazing!
Thank you. I had done the math on how much obstruction the mini-filter wheel would cause before I decided to use it and it wasn't too bad. However eventually I had to admit that the hyperstar works best with a color camera. So now I use an ASI2600MC Duo on the hyperstar instead of a mono camera.
Great video bro, have one for a while. Big up from east Ireland. subbed 👍🏽
Thank you and much appreciated my friend :)
Nice video, I've had my Orion Skyview 8 for 22 years never thought about imaging with it until now. The focuser is junk, I'm looking for a good one that will drop in with little effort, I don't see your link that you mentioned, thanks again for the great info
Thank you. The focuser links are in the video description: Focuser Upgrade for common Skywatcher/Orion reflectors: s.click.aliexpress.com/e/_DFGuhm1 Focuser Upgrade for GSO or custom reflector telescopes: s.click.aliexpress.com/e/_DD5wVXT
Hi mate. In PI you can measure SNR and FWHM to compare. I recently had a problem with focus changing. I did these measurements for different stacks and was able to show BXT improved things so i could use the higher snr stack.
1:45 if this eyepiece design displays coma and chromatic aberration over a relatively large proportion of its outer field, I’d be interested in a direct comparison between it and the same focal lengths in the Nagler, Delos and Ethos oculars. Thank you for the great two-part review-excellent watching.
Thank you. I will try to do a comparison with the others if I can get my hands on them. I ended up selling my Nagler eyepiece a while ago and I don't have the Delos or any Ethos on hand right now.
Fantastic, thank you very much.
Thank you your review was the best I have found on TH-cam. Everyone else is pushing an agenda trying to promote or sale something. I am actually really pleased with the result of the non modified DSLR. For the price you pay you have mange to capture an image that is actually comparable to a setup that cost almost 3 times. The smart telescope is not bad for the price but due to the small sensor is to weak to compare with a full frame camera. For me the grand picture is more important that pixel peeping so for this reason are lean towards the full frame sensor of the DSLR and I am really happy to see that an non modified censor can hold up against dedicated astronomy camera. I am quite convinced of the dslr was modified with will be extremely close to the Astro camera. I am planing on getting a new mirror less full frame with 24 pm or less. I have found that Sony and Nikon have developed some amazing options where Nikon has a camera that offers 500 second exposure out of the box. I feel that this setup might punch really hard against a Astro camera especially when take in to account the price difference and the fact that the mirror less can also take shots during the day. What is your opinion?
Thank you so much. I always strive to provide a completely honest and unbiased review. Astronomy/astrophotography have been my passion for most of my life and I just enjoy sharing that with everyone. I just ask that anyone who enjoys my videos and wants to see more of them shares them with their family and friends who might also be interested in astrophotography. As more people watch my videos I can make more of them :) Unmodified DSLR cameras can get some amazing images especially with some fast optics. I took this one with the unmodified 6D and a 135mm F2 lens th-cam.com/channels/Oigpu7c-bT3C6oItFLQq7Q.htmlcommunity?lb=UgkxR1wZeVrefbo7mHd823iUnjLMReG8YuTK The fact that you can get them for so cheap on the used market makes DSLR cameras a great deal if you need a large sensor and don't want to spend as much for an astro camera. And as you said, they can also be used for daytime imaging. And a modified DSLR would be a lot closer to the astro camera on targets that have Ha (like the Viel nebula) than the unmodified one I used in this test. I noticed the DSLR was missing out on a lot of Ha due to that. But I mainly use the DSLR for timelapses now so I couldn't justify modifying it. I scenario where I found the DSLR really struggling against the cooled camera was when I was imaging from a really hot location (night time temperatures around 20-30C. In that case I found I was dealing with a lot of walking noise (since I was using a star tracker that couldn't dither). That would be less of an issue if you are using an actual mount and guiding so you can dither your images to reduce noise. Although modern mirrorless cameras have very capable sensors, one thing to watch out for is that many models from all brands suffer from the firmware pre-processing all the RAW files. That means you can't always properly calibrate your data with calibration frames. In some cases you might end up with faint colored rings in your images if you stretch them a lot. I experienced that issue with several Fuji mirrorless cameras and I know Sony, Nikon, and even many Canon models suffer from those issues. They likely won't be a problem if you don't stretch your images to reveal as much faint detail as possible, but just something to watch out for. The biggest advantage of the SeeStar is portability and ease of use but of course that comes at the cost of a small sensor and limitations like an alt-az mount. Each of these setups have their advantages and disadvantages so I ended up with all 3 so I can utilize their individual strengths.
Putting them side by side or overlaying them would be very helpful.
I have started doing that when I compare images now. I will be sure to compare them that way in future videos.
Waiting for the flat earthers to find this video and call you a paid nasa shill
And I am waiting for NASA to call me and offer me money to shill for them. So far no calls.
Those are awesome scopes, all the way back to the orion 100ED and celestron 100ED versions. When the 120ED refractor first came out, one of my bosses insisted I take the floor model home for a while and I didn't argue. I assumed it would have some color being only f7.5 and a doublet. I was surprised, visually it was amazing even at ridiculous 2.5mm eyepiece power, even the moon showed no color. On APS c dslr, it had a flat field and didn't have any purple stars like the 80ed i used to own did. But the boss later did ask me to bring it back and I eventually sold it to a terminally ill customer on the waiting list for a stellarvue 115 that was not likely to get it in time. I was able to personally vouch for that sample and he was happy with it.
I had the chance to look through the 120ED as well and found it to be really good. I was a big fan of that series for visual use. The FPL 53 they used made a big difference for color correction.
Axiom LX was made by JOC, same as the first series of meade series5000 UWA and later explore scientific 82deg. I am curious if it is really 10mm, it is probably 9mm, since it doesn't make sense for JOC to make both 8.8mm and 10mm optics set, and scope companies tend to use numbers that represent their earlier famous eyepieces focal lengths. When ES became the exclusive source of these eyepieces and doubled their prices, meade and celestron were forced to switch suppliers and we got the luminos which isnt as good. The axiom LX 10mm is a nagler type6 copy, with more eye relief, and modern coatings from china are still better than what was available when the type 1 naglers were made. You can also find variation in views between different examples of the same types of naglers because the coatings evolve over time but televue does not advertise that nor make any distinction between what coatings a particular eyepiece has. I wasnt a huge 9mm nagler fan either, I preferred the 8.8mm meade, which was more like a type 1.5 nagler since they made an improvement, but the type2 nagler hadn't come out yet, and when it did it was totally different and only offered in 12, 16 and 20mm and didnt replace the type 1. The 14mm UWA didnt kidney bean as bad as the 13mm nagler, and is one of my favorites. I used it less after scott gave me one of the first batch of 14mm es100s, which beat the meade in every way, mine was an old smoothside, so very old coating technology. The only thing the meade was better at was being useable in 1.25 limited scopes. That and being really into old smoothside meades, I never parted with it until it, and almost everything else I owned was parted from me. And the 25mm plastic bodied celestron is not a plossl, it is a 3 element SMA, and is a bit wider at 56deg than a plossl, the main problem with it is the inner body is shiny black and can cause internal reflection. I actually like the 15mm and 20mm versions of it, they are much wider, 65 and 70deg as they both have the same size field stop, the 15 is wider. I only use them on slow scopes, f10, and mainly for long lines of public outreach, along with the 2" celestron e-lux which is in the low to mid 60s range AFOV. I found that the 3 element design, there was better throughput than my 5 and 6 element superview and QX/es70 wide fields, that were in my outreach kit. The 3 element ones lived in my 8"lx200R ota case, so i always had a set ready to go as that rig lived in my car back then. In regards to throughput, I found my 15mm superview which was 4 element, to be noticeably better than my 15mm meade QX. I did not have the 15mm celestron 3 element back then. I remember showing the ring in the 20mm at an outreach from less than dark skies, and it was very bright and easy to see for everyone. When I was trying different outreach eyepieces on it, the cheap one was the brightest view. I don't compare it to premium eyepieces because I dont want public gunk on my premium eyepieces, unless it was a high profile event, and even those usually got my meade 5k, axiom LX and es100s. I rarely risked my vintage japanese eyepieces or even my 31 nagler on the public, who wouldn't see the difference anyway. The TMB planetaries were also great for public, since they werent that expensive, and with the cup twisted all the way up there was little chance they would touch the lens. This also applied to the axiom and meade 5k eyepieces. Now that I had to start over a few years ago with only covid check money, a little savings and scope hoarder friends who gave some good deals, along with craigslist and cloudy nights deals in 2020 and early 2021 before the major price increases, I managed to build a respectable eyepiece collection again, including slightly later rubber eyecup versions of the 4000 6.7, 8.8 and 14mm UWA, and the 5k 4.7mm uwa. I HATED the eye relief and dim views of my early smoothside 4.8 nagler, so i never considered bothering with a series 4000 4.7mm UWA, unless just to complete the collection if it fell under the $100 point. I probably wouldnt use it much. I did happen to also get a 7mm type 1 nagler smoothside because one came up for $100 because there was some chipped off the barrel. Coincidentally i got a similar deal on my 4.8 20 years ago for the same reason. My big boys are the 20mm WO XWA, the 28mm megaview (wo uwan), which is the BEST non nagler in the 30mm range, even the axiom/5k/ES version doesn't touch it. I miss my 31 nagler, but that 28mm performs just like it but I wish it was a 31 not a 28. The meade PWA is the same eyepiece by the way. 28 however is ideal for f4 because it is 7mm exit pupil. The 23mm axiom LX, as well as the 24mm UWA and es82 versions are also right up there with nagler performance, but the 30/31 versions couldnt quite match the 31 nagler. I had regretfully sold my 23 axiom LX when i was downsizing because my 20mm ES100 had the same true field of view and I really liked looking through those 100s, and I wasnt really using any fast scopes at the time other than a televue 101 which is a flat field scope, so I didnt notice the edge issues with the 20 until i brought it to a star party and compared it to the ethos in a 20" f5 obsession. I have 17mm and 22mm LVWs, as well as a 24mm es68 to round out the holes in my well corrected widefield set. I would like more 100s, but I probably have to stick with just the one 20mm and barlow it with my GSO 2" ED barlow which can also make it approx 13mm by threading the lenses on like a filter. Justifying not spending any more money here. Another shining star was the 5.5mm uwa that meade had after they had to change suppliers. It was the last eyepiece i got before getting robbed in 2018. That thing was like a type 6 nagler. I had a 7mm type 6, and when I was using both of them with my tv101 in dark skies, it was like just switching powers, no performance or comfort differences between the nagler and the meade. By the time I was rebuilding my collection, they werent available new anymore, and nobody was selling them for the appropriate price used for an eyepiece that cost $99-129 new. I ended up with the 4.7 with some coating damage for something crazy like $35 from one of my friends.
Thank you for the info. I always like hearing about everyone else's experience as sometimes eyepieces that work well for me might not work as well for someone else. I love the 100 degree XWA eyepieces as well and since I got some good deals on them I don't even mind using them at star parties and public outreach. Sorry to hear you got robbed. That is always heartbreaking. I had always hoped to try a 5.5mm UWA but haven't had the chance yet.
You should try vixen LVW and orion lanthanum superwide which is the same eyepiece, as upgrades to the stratus which is a chinese attempt at the same design. The performance and edge sharpness is much better, on par with pentax XW and XL. They are 65deg and 20mm eye relief, and you can see in the cosmetics and mechanics that the stratus/hyperion was a copy though the lvw is a little smaller, but also 2"/1.25" hybrid barrels
Thank you for that info. I will see if I can get my hands on those to try :)
