The Sky Watcher doevetail adaptor is solid and much cheaper, allows you to fit a ball head with arca swiss or any other standard camera mount www.amazon.co.uk/Sky-Watcher-Star-Adventurer-Ball-Adapter/dp/B00YWPCNJU
I recently discovered a cute trick to avoid marking the pretty dovetails. I happened to have what's called "Thermal Copper Heatsink for CPU GPU" 15mm x 15mm x 1.5mm (check on Amazon). They usually come in a package of 10 for less than ten dollars. Being quite soft, copper will grip both surfaces securely without marking. If you tend to put the dovetail back in approximately the same place all the time, you can use "Scotch double sided tape" (the thin transparent kind) to position them. 15mm is about the height of most dovetails and 1.5mm thick is enough to survive quite serious clamping. I normally use the ADM clamps but they are not typically made for small mounts and the weight would be too great anyway.
A very cheap alternative: Larger cardboard packages are often secured with plastic ribbons, some of them fit nicely to the clamping surface of a dovetail bar. Just keep one of them after unboxing.
This video is exactly what I needed for my future set up. I really love your tutorial video because of how to the point and relatable it is. That scope is really nice too.
Yep, it's in the plans for the channel! It will have to be limited at first as what I'm thinking about involves taking some time off from work... Maybe one day I'll be as big as Trevor and YT will be my work :-p
Thank you, awesome video! Sharpstar is going to be my first telescope, that’s why I’ll be glad if you’ll dig deep in details, especially from the point of view of the newbie.
I know... I used to have the Vixen dovetail version of it with my old AZ-GTi and I found it quite flimsy, I wasn't a big fan of it. I've told the Vixen+Losmandy version is better though...
Much cooler than space/redcat! I got the same scope with the ZWO auto-focuser and the reducer a few weeks ago. I have only been able to use it once so far, but it's awesome! Pretty fast and very compact. Good luck with it!
Thanks for uploading. I got the chance to witness a rocket launch in 2018. Memorable experience. I shared a pretty fun montage of the journey to my channel.
Thank you Cuiv. You are a bundle of energy. Two ideas for you: 1) Look into Green Swamp Server. I know people are getting guiding as accurate as 0.10" RMS. It is designed for Synscan, Skywatcher, Atlas mounts idea #2. Sharpcap live image capture/stacking as well as the option of saving individual frames. Unbelievable! Get some rest man!
Thanks for the suggestions Dan! I actually started using GSS a few nights ago! It's quite impressive, but two nights ago I started having terrible guiding that stayed with further calibrations (with or without the GSS Goto DEC pulses). The moment I switched back to EQMOD (during the same night), guiding was back to normal... So I'm not sure what to think! I'll have to test it again at some point...! As for #2, I may indeed feature it, but I prefer to use Dark's EZ Live Stack in PI, as it's more powerful! Thanks for the ideas! And I never need rest, I'm a machine :D
@@CuivTheLazyGeek Remember Rusty the Tin Man in the Wizard of Oz....Reinstall GSS and see if it helps...Using PhD2 at present but if I don't execute it as Administrator I have nothing but grief
Wow, Cuiv, we have the exact same super portable telescope setup! I am using 071 with this setup right now but I have a 533 too if I want to "zoom in" a bit. The performance of the Sharstart 61 EDPHII with the 0.8 RF is really impressive. I had my first light last week and the stars are sharp and round all the way to the edges with the aps-c sized sensor. You will not be disappointed. I use ZWO ASIAIR Pro to control my rig which helped me get rid of the computer to make the setup truly "Portable" haha. Here is an image of my rig, I would assume your finished set up will look pretty similar to mine since we have pretty much exactly the same equipment :)) And you could see the First light image of NGC 7000 in there too. It only has 55 min of exposure time before the cloud rolled in and I have to end my session. BTW don't upgrade the firmware to 3.22 August 9th version yet.

I will need to mount a small computer on my rig at some point (I've been waiting for the ASIAir Pro to add autofocus for over a year now). Very interesting on the 3.22 firmware, I will check at my next session, thanks for the tip! That wedge tickles my curiosity! Thanks for the feedback :-)

@@richardxiong6926 Richard. I love the set up- can you please let me know what you used to attach the asiair pro to handle of scope and want size dovetail plate you used at base of scope to attach to mount-thanks for your help
Thanks for the suggestion Fred! I do touch upon it to some extent in this video: th-cam.com/video/4pqowyaQy-M/w-d-xo.html But yes a proper autoguiding guide video :-) would be nice indeed! Thanks for the suggestion!
Hi Cuiv, thanks for a great video again, i'm a big fan of you channel! Very interesting info about the Astromechanics adapter for Canon lenses. That is a great piece of equipment I think i need to have :) The 2" filter adapter mentioned, is that only sold by the japanese company you link to? (I can not see the 2" spacer on Astromechanics pages, only a 1.25" and a M36 adapter) I'm using 2" filters, so I would love to get that 2" version. I assume the electricsheep company only sell to japan? Best regards from Norway!
Hi Cuiv, Our rig is very similar and we are really new. Would you be so kind as to do an automated session with the AZGTI and give us an example of what we are striving to create. Love watching your videos!
Thanks Cuiv. Stupid question: am I right in assuming that the guide scope does not connect directly to the mount? I'm using the ASiAIR+ so I'm guessing the guide scope only connects to the ASIAIR via USB? I'm looking for a travel mount to take to Southern Africa. The SW Star Adventurer GTi/ iOptron Skyhunter looks like the perfect option but there's a huge backlog in availability. I guess the AZ-GTi is the next choice. It looks like you're pretty happy with it...
So glad I found your channel!!! I have a question about the canon lens adapter by Astro mechanics. Can it be controlled by the ZWO EAF or is it used in place of the EAF for Canon EF lenses? I am using an ASI Air with an iPad (no PC). The ASI Air is compatible with the EAF for sure (both ZWO). I would like to use EAF with my canon lenses. Thanks!!!!
Welcome to the channel Robert, and thanks for watching!! As you undoubtedly found on the other video, the Astromechanics is standalone - it doesn't require an EAF (which is great), but at the same time it means it likely will not work with the ASI Air, which is really, really a shame...
i love your videos. just subscribed. i'm working on a similar compact set up for my dslr plus lens. Have you considered getting the asiair so you can use a phone or tablet instead of bringing the laptop?
Thanks Marko, and welcome to the channel! Unfortunately the ASIAir Pro doesn't do autofocus yet, and even when the feature is added, it won't work with my lens focuser (only the ZWO EAF)... so it simply cannot work for my setup at this stage... autofocus is very important to me...
I had a cheap hot shoe red dot finder bought off ebay in the past - are you planning on mounting a guidescope there? Your guess is probably as good as mine as to what works well!
Hey Cuiv ! Do you think the astromechanic ring for focus is better than a ZWO EAF fixed on the Astrodymium Ring System on this setup ? Also, is a filter wheel fits between the lens and the camera (+the adapter canon to zwo) ? Thanks !
You are doing some amazing stuff. I need some serious help. I want to us the ASI 294 MC Colour dedicated camera with my Canon lenses , 100-400L f/4.5 to 5.6, 24-105L f/4, 17-40L f/4, but how do I control the Aperture ? OR will the lens remain fully open ? Since there is a MF/AF sw, so focus in MF not a problem. I also have the Sigma 24mm f/1.4 but at 1.4 huge Coma effect, so have to stop down to 2.8 or more. How do I select a particular aperture ? If there is solution, that would be just great. At one point you said very simply that the Camera USB port gets connected to the Adapter USB port, and you have control of Aperture, does that mean I don't need to carry a Laptop and everything can be done with the ASIAir PRO App. It would be great if you can give a link to that adapter so I can order online.
Hi Cuiv, I’m lazy too! At 2:20 you said that you can plug the autofocus adapter into the USB port of an ASI camera. Does this mean an asi air could control its focus? That would be awesome!
I haven't used a polar scope in years... I use Sharpcap for precise polar alignment (no need for a polar scope), you can see details here: th-cam.com/video/iw8AfoPmrIM/w-d-xo.html
I want a no computer setup for my dark sky sessions.. the AA batteries are greater great for the mount to compliment my K1 DSLR.... but what about polar alignment.. is it close enough to polar align via azimuth and latitude angles? I put a lot of effort into making sure my tripod is level and when I do my latitude hardly needs any adjustment each time I set up
Question, how would one lock the lens aperture (The iris) on an automated ef lens? There are manual lenses I think that allow one to adjust the size of the iris with the lens and without the aid of a camera.
Excellent video and quite clear. I have a question though, and I hope you can help me: how could I get th4 right focus for my set up : ZWO 294 Pro Color + Samyang 135mm F2.0 + Canon EOS adapter? I've tried different ways using the 16.5 mm and the 21mm extenders and rings with no good results. Thanks in advance.
Mmmh it sounds like your sensor is too far from the camera. You need to be 44mm from lens flange to sensor itself (which is recessed by 6.5mm in the camera body, and another 11mm by the removable T-ring). Not sure how wide your EOS adapter is though!
@@CuivTheLazyGeek thank you, I used the small ring that comes with the cam, looked for the best position + ZWO 294 and it worked. So, no extra adapter is required , Just this metal small ring.
Excellent question! You may want to check my previous videos on guiding and on connecting to the AZ GTi mount: th-cam.com/video/4pqowyaQy-M/w-d-xo.html . Basically you don't want to use the autoguiding port, even if it's available! As much as possible you want to send guide pulses directly to the mount using an ASCOM or INDI connection!
Hello Srinivasan! I guide directly using ASCOM connection to the mount over Wifi, you can check towards the end of my video to see how that ASCOM connection is done: th-cam.com/video/xJmntIr50lk/w-d-xo.html
It's the Astromechanics adapter, you can see my review here: th-cam.com/video/WtoxBm3dzIE/w-d-xo.html . Most of my issues with the ASCOM driver have now been fixed!
Hello Cuiv; not able to read a lot in the page of electrosheep , all japanese !! Is there a for western people understandable internet page/ shop? Cheers Stephan
Hi Cuiv, thanks for directing me to this video where you introduced the Sharpstar scope. Like i said, i've got the 76 EDPH, but the rebranded one from TS Optics, you're right, beautiful scope, but unfortunately i wasn't able to achieve balance with the stock tube-clamp and dovetail, i had to invest in PrimaLuce lab gear (witch is pretty much the same color 😅). I've done two images with it thus far, one LRGB ( astrob.in/d1lnlz/C/ ) and one narrowband, not bad, but i think i got some tweaking to do, i see a little bit of tilt and blue halo's. Curious about your findings !
Oh yes the balance is impossible with the default dovetail! Right now I'm just using it completely unbalanced :-D I haven't seen such halos on my images, but then I use dual band filters so that could be the reason... Also I am one of those guys who doesn't care at all whether stars are not pinpoint, or halos are there or not. I've discovered it's simply much healthier not to care :-)
Thanks Stephane! Yes, I had one of those before (well, the Vixen saddle one), and it felt a bit less stable than the default one, so I think I'll just start with the default dovetail-marring saddle for now!
I did use it a couple of times, I think closed down to f2.8 or f3.2, and it performed decently - I'll need to try it again! Lenses, as with everything else, have a lot of variability!! :-(
I use a cheap Sony audio recorder (for classes, conferences, etc.) with an old, old mic. Then I need to synchronize with the video, but I've become proficient at that. Does it sound very bad?
@@CuivTheLazyGeek Sounds very good. If we continue to make videos (Sarah and I), then I'm going to have to improve the setup. Using the internal camera mic is not the best way to do this.
Congrats on the Sharpstar! It's an awesome little scope, Redcats are Overated!! 😁 I use the 76EDPH and am inlove with it, it's so good! Check out the #gallery channel on the nina discord, i uploaded the Elephent's trunk nebula shot with that scope.
Aww, I love my Spacecat! Admittedly I don’t have much to compare it to besides cheap cannon lenses but for the $ I think it’s hard to beat. No flatterer required was what sold me. The Sharpstar is a cute scope though, I’m excited to see it in action!
I think what turned me away from the RedCat / SpaceCat was the helical Focuser - you need some DIY work to automate such a Focuser, and even then there would be a belt in the way (most likely)... Otherwise I think I'd have done like everyone else, and just sprung for one! Flexible back focus is awesome!
Hi Cuiv, FYI those screws holes are 1/4-20 not 3/8. Also get that ADM VPA-AZGT- V no screw holes and a better fit!

Hello Cuiv; not able to read a lot in the page of electrosheep , all japanese !! Is there a for western people understandable
internet page/ shop?
Cheers
Stephan
Unfortunately no English page...! I put the link for reference only, I'm not aware of equivalent rings anywhere else...
Keep up
Absolutely :)
Hi Cuiv, thanks for directing me to this video where you introduced the Sharpstar scope. Like i said, i've got the 76 EDPH, but the rebranded one from TS Optics, you're right, beautiful scope, but unfortunately i wasn't able to achieve balance with the stock tube-clamp and dovetail, i had to invest in PrimaLuce lab gear (witch is pretty much the same color 😅). I've done two images with it thus far, one LRGB ( astrob.in/d1lnlz/C/ ) and one narrowband, not bad, but i think i got some tweaking to do, i see a little bit of tilt and blue halo's. Curious about your findings !
Oh yes the balance is impossible with the default dovetail! Right now I'm just using it completely unbalanced :-D I haven't seen such halos on my images, but then I use dual band filters so that could be the reason... Also I am one of those guys who doesn't care at all whether stars are not pinpoint, or halos are there or not. I've discovered it's simply much healthier not to care :-)
Can you change the saddle on the AZGTI to one that doesn’t mark dovetails?
Yes you can.

Acapulco Astro: thanks for the link - this is perfect and will be my next purchase

Thanks Stephane! Yes, I had one of those before (well, the Vixen saddle one), and it felt a bit less stable than the default one, so I think I'll just start with the default dovetail-marring saddle for now!
The Canon 50mm f/1.4 is diabolical for astro photography, the coma is just about the worst of any lens I've used, horrid, throw it away :)
Diablo!
I did use it a couple of times, I think closed down to f2.8 or f3.2, and it performed decently - I'll need to try it again! Lenses, as with everything else, have a lot of variability!! :-(
Cuiv...how do you mic yourself for these vids?
I use a cheap Sony audio recorder (for classes, conferences, etc.) with an old, old mic. Then I need to synchronize with the video, but I've become proficient at that. Does it sound very bad?
@@CuivTheLazyGeek Sounds very good. If we continue to make videos (Sarah and I), then I'm going to have to improve the setup. Using the internal camera mic is not the best way to do this.
61edph sharpstar? :)
Yep! v2 of that scope (now a triplet rather than a doublet!)
Cuiv, The Lazy Geek I have one as well:(( but no weather
Cuiv, The Lazy Geek yeap:) it looks like nice little scope, mine is from tsoptics:)
Congrats on the Sharpstar! It's an awesome little scope, Redcats are Overated!! 😁
I use the 76EDPH and am inlove with it, it's so good!
Check out the #gallery channel on the nina discord, i uploaded the Elephent's trunk nebula shot with that scope.
Aww, I love my Spacecat! Admittedly I don’t have much to compare it to besides cheap cannon lenses but for the $ I think it’s hard to beat. No flatterer required was what sold me. The Sharpstar is a cute scope though, I’m excited to see it in action!
I saw that, it's a beautiful and very sharp image!! This series of scopes is a killer!
I think what turned me away from the RedCat / SpaceCat was the helical Focuser - you need some DIY work to automate such a Focuser, and even then there would be a belt in the way (most likely)... Otherwise I think I'd have done like everyone else, and just sprung for one! Flexible back focus is awesome!
Cuiv, The Lazy Geek yes the focuser is the weak point in my opinion. It’s a pain to get it just right.
First!
As always! :D Thanks for watching and commenting!
Creepy....
