Assembling my new ASI 6200MM with EFW and OAG
Thank You. This is highly interesting and makes the difficulties of implementing the mosaic mode very clear. I had already suspected that mosaic imaging with the Seestar would be very lengthy, but also underestimated the necessary calculation time. It might be good to be able to switch off internal stacking completely. On the other hand, external software is then necessary, Siril cannot automatically assemble mosaics and Pixinsight is quite expensive.

@@the_space_koala 정보 매우 감사합니다😀
15 hours of precision collimating a telescope is so relatable😭😭😭
You sound so happy! I love when people share that passion! I sound like that when photographing aurora (in germany not as rare as one might think!) or the sun or when my results of a night out photographing the sky comes to fruition :D
There’s a chance of aurora again tomorrow 😍
@the_space_koala i may have yelled in excitement as i saw the x7.1 flare 15 minutes after it happened! To bad it was night here, otherwise i may have had it on camera too. I've already placed my camera if the clouds decide to go away :)
fingers crossed for another night of pinkish skies :)
Excellent informative video. I'll wait till November for the Dwarf 3 or S30.
Excited to see how they perform! I’m waiting on both scopes
Ugh that thousand cut edit is going to give me a seizure
Another excellent video-thank you, SK! I hope the smart telescope industry inspires newcomers to catch the astronomy bug. I also hope you had the chance to take advantage of the pristine skies for your own projects. In your opinion, how do you see smart telescopes shaping the field of astronomy now and in the future?
For me smart scopes are for electronically assisted astronomy not for astrophotography. Of course you take photos but with the current designs you’ll just never reach the quality we expect from an astrophoto. The direction seems to be going towards even smaller/simplified designs, understandably so. It will stay a valid option for people new to astronomy and I think it’s great for that but I don’t see them take over because as long as they don’t make 8”+ designs, traditional scopes will keep having an edge
@@the_space_koala thank you!
Thanks for the video. I suppose that this scope could be used in equatorial mode, improving the framing and mosaics?
A lot of people are doing it however there is no official support for it. People put it on a wedge then the scope compensates for not being level which reduces field rotation
Please use a counterweight to balance not only the polar axis but also the tripod! I kept waiting for the entire rig to topple over!
Hope you’re not too disappointed it didn’t! 😉 it is actually very stable as is!
@@the_space_koala Well... you have easily $20k sitting on that tripod... just step back and look at it hanging there to one side... I'd hate to hear that it took a dive...
Thank you for this analysis. It is refreshing to see, that some people do understand the concept. I have spent counless hours on Clody Nights and in my local club explaining this to people who simply refuse to let go of this daylight photography concept. It is so frustrating, how many astrophotographers completely misunderstand it. TLDR; f-number is a completely useless metric in astrophotography. Aperture dictates light gathering "speed" and focal lenght dictates the FoV. Optimally you need two telescopes, one with a higher FL for small objects like distant galaxies and one with lower FL for those nice, wiedefield nebulea. The bigger the aperture you can aford on both telescopes the better obviously up to a point, where your mount can support it. (Things like under-/ oversampling given your cameras, seeing, light polution, wind, etc. will obviously play a role in determinig the optimal setup.)
Thank you, I agree with everything you said. I spent more than a week making this video, preparing animations etc and while some people got it, I still see some reactions that make me think I wasn’t able to get my point across.
Thank you for the information, now I can't wait until this software update comes on the market. I like your video very much.
Glad you liked it!
Thanks for your excellent videos... The SeeStar jumpstarted my AP adventure. Since the Dwarf 3 has much improved auto AP with a better sensor and EQ, maybe ZWO will catch up with an evolved version. Regards, Michael
I think they will do it eventually. So many users are asking for the EQ mode they’ll be pressured into implementing it 😁😁
Excellent. You used the word modulate. Comfortably. Properly. Are they ready for it?
I've been wondering how they would implement mosaic - thanks for the insight into how it works
Thanks for watching!
I have no interest in a Seestar but watched this anyway 😉
and just when seestar caught up to vaonis with the mosaic, vaonis moves ahead with multi-night stacking
I saw the update - competition between these companies is the best thing that can happen to these products 😊
can you please do a more in-depth video on how to stack the mosaic files? maybe even using a free software like deepskystacker?
I don’t believe DSS would be able to do it as you cannot define an external registration template. A good free option is Siril! I’ll be showing more details on the processing when I do the video on the smart scope calibration frames as well!
Good job, make a lot of sense what you explained, I used also Seestar in equatorial Mode and works fine, but they do not an option to set it in equatorial mode works because the sky alignment process, any changes in beta about equatorial mode? Thank you for your time, great place you have all skies for you.
No they have not added any EQ mode support yet!
Very easy to understand your explanation. I can't wait to use the mosaic mode on my Seestar.
Great video thankyou.I'm waiting for my Dwarf 3 to come so hopefully I'll never have to use the mosaic on my seestar, especially if it's a lot of hassle.
Seestar S30 will be out soon which will probably have a similar FOV and a 4K sensor like the Dwarf 3.
I’m waiting on my Dwarf 3 as well - then we will see who wins the ultimate smart telescope showdown 😁
Hi, a great video thanks. I'm excited and cannot wait for the release. Rick from Australia
Thanks Rick! I hope they release it soon, it’s been in testing for more than a month
Great video and thanks for sharing. It seems as though it has moved from a quick and easy session snaping numerious targets in one night to a much more dedicated affair. Not what i imagined it was going to be and not for everyone i suppose given the time required.
I agree - whoever wants to keep it simple should definitely just stick to the single frame mode! It’s nice to have this option though for those who like a challenge
@@the_space_koala I on the other hand run out of sky after a couple of hours thanks to all the trees and houses around me. 😀😀
I admire your courage and skills! This is kind of scope is observatory grade, should not be moved too much. Thank you for the video!
Thank you. Without an observatory I don’t have a choice though, this scope belongs in the mountains not on my light polluted balcony 😁
It seems a bit strange that one is going to buy a seestar for the convencience, and also invest in pixinsight costing about as much as the smart telescope and invest a lot of time actually learning how to use it.
I think the thing is they will buy the seestar for the convenience, then fall in love with the night sky and want more
@@the_space_koala Yeah. You are probably right.
Very helpful explanation of how this update currently is. The current efficiency issue is going to limit people to smaller mosaics IMO.
I agree, at least I hope it’s the case and not some insanely noisy images to come 😁
Great video! Excellent analysis of the built-in mosaicking process! “20 minutes per region”! I like the “infinitely better” result. Do you use GraXpert?
Very informative, what a beautiful location, incredible.
It really is! Not to mention the night time view...
Very good telescope. I would transport it on a mountain and use it for taking new objects, like the new comet C/2023 A3 (Tsuchinshan-ATLAS) and make a mosaic. M 31 start to be boring in long run.
I did take it to the mountain and used it for the comet, but doing a mosaic on a comet is next level difficult I'm afraid :)
Great info. I wonder if an equatorial mode for seestar would help the mosaic function run more efficiently.
I think anything works better in equatorial 😁 if there was an EQ mode you’d be able to do regular mosaics
@@the_space_koala True, what I'd really like to see is a VCR function, where I can pre program various objects to be imaged throughout the night.
Yes this would be very helpful! It could also help with field rotation if you image the same object at the same time every night for 1-2 hours max!
I wonder if it is possible to 3d print a tiny eq platform style tripod head.
yeah I think you just need a wedge and point it more or less to the North (or the South). Polar alignment wouldn't need to be accurate because it's going to plate solve and build a model regardless!
Excellent explanation! I was wondering about this new mosaic routine-it's not without its challenges 🙂 Are you still enjoying the clear skies of beautiful La Palma, or have you already returned to ???
It is definitely a challenging process to get a decent image out - I hope they will keep working on it to make it better!
@@the_space_koala Yep, or put a bigger sensor and a field flattener in that telescope, clear skies!
I think the flattener is already included - the field seems entirely correct! A larger sensor would be great but would increase the cost and make calibration frames even more necessary
Great video. Thanks 😊
Glad it was helpful!
Great introduction, thx. And also thx for a closer look to processing in pi. Very profound. And I must say that the result is really good. The first time where I can honestly say this. Ok, very bright object, but very short integration time. Mosaicmode seems not to be the real game changer for now, but we will see. I'm looking forward to your calibration frame video. We will see if I will get in love with this small thing.
Thank you I’m glad it’s helpful!
I've been using mosaic mode for a month or so. The hardest part for me has been stacking multiple days of integration correctly.
A few months? I didn’t realize it’s been out that long, I only got it a month ago!

Yes, I tried this with the vespera and it was a mess. I didn't recognised that the seestar has it now. But I see light at the end of the horizon.
That’s just sunrise 😁
Seems that my previous post was removed. … Try “Hubtische” from Schäfer in Switzerland.

WiFi station mode might only allow for the 2.4Ghz WiFi, which is much slower than the 5GHz ASIAIR hotspot.
I use multiple ASIAIRs so it’s very convenient to be able to switch between them in station mode. I don’t mind that much about the download speed. I have a VPN so this way I can also start them and check on them remotely
@@the_space_koala Good point!
I have a MacBookPro with Apple Silicon (M1Pro), which natively runs the mobile ASIAIR app on macOS! I only use my MacBookPro for all of my imaging with the ASIAIR app. I always connect to the ASIAIR mini 5GHz WiFi hotspot, which allows for very fast download to the MacBook. In general I connect a 2TB SSD to the ASIAIR, which works flawlessly.
I used to do the same on my Mac, but now I am a beta tester for the ASIAIR and I wouldn’t know how to download the test version for the Mac so I gave up on that 😁
I love the tripods!
So true! I can fully relate! I only need to drive 30 minutes to the next dark site in the Jura mountains. Still if I forget anything…
Oh, 30 minutes from a dark site.. you’re living the dream
@@the_space_koala Not very dark, but good enough. Not like going up to the mountains. That takes me 2h… I usually go into the Haute Valais for dark skies.
The area around Adelboden is surprisingly dark… but weather is not as good as the Tessin ;-)
Great video!
Thanks!
That was absolutely amazing! I was in the Swiss Jura at the time…
Do you have a guide scope?
I don’t use guide scopes, for deep sky I use an OAG (off axis guider)
@@the_space_koala Me, too. Askar OAG is great.
Well done, fellow Swiss stargazer! Cool, Rainbow mount & C14, perfect match!
