Hi everyone. I made a new video showing how I process data of the Dumbbell nebula (from the SeeStar S50) here: th-cam.com/video/WqNxzFmjRZ4/w-d-xo.htmlsi=IJrif0VR50IB-fpr It's part of my SeeStar Roundup series (in collaboration with @AllStarTelescope) where viewers send in their data of the object of the month (this month is the Iris Nebula) and I process all of our data together. 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?

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

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!!

Hi - what add-on tracker mechanisms would you recommend for this telescope?

My S50 is on the way , can't wait to produce some of these myself

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.

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 👏👏👏

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.

I have the 3. Just spend the extra 200 bucks on the 5. Trust me.

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.

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.

That’s some significant vignette. What size sensor are you using? Are you using a 1.25 or 2 inch?

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.

cant download zlib =(

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!

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.

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.

Very Helpful! thanks

How’s the mini filter wheel in the light path when using the hyperstar? Amazing!

Great video bro, have one for a while. Big up from east Ireland. subbed 👍🏽

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

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.

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?

Putting them side by side or overlaying them would be very helpful.

Waiting for the flat earthers to find this video and call you a paid nasa shill

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.

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.

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
