This video shows my process workflow for Polar Alignment when Polaris is not visible. My imaging targets are on that particular side of the backyard where the North Celestial Pole (Polaris) is behind a huge tree. The imaging equipment I used for this process is as follows:
#zwo #asiair #celestron
Telescope: William Optics GT71
Main Camera: ZWO ASI533MC Pro
Guide Scope: William Optics Slide Base 50mm
Guide Camera: ZWO ASI120MM Mini
Mount: Celestron Advance VX
ZWO ASIAir Plus
I kept the exposure time to 5 sec for alignment as I was using the Optolong L-eXtreme filter. Exposure may be much shorter if no filter is used or some other filter such as Ir/UV Cut or L-Pro, etc. is used.

Best video I have seen on steps using All Sky alignment!…easy to follow!
Thanks!! I’m glad the video is helpful. Cheers!
Good show keep it up
Thank you.
Thank you! I'm trying this for the first time later tonight, very helpful to see a step-by-step guide.
Hey Jason,
Glad it was helpful! Thanks for watching and subscribing. CS!
Very Impressive Video. Nice walkthrough! The whole Process is Interesting
Thanks. I’m glad you found it useful.
Just planning to try my new ASIAIR for the first time from my balcony I cannot see the polaris by about 10cm because of a roof :D So will be trying to day, thanks so much for the video :)
Thanks! All the best for your trial of ASIAIR!! Hope all goes well!
Clear skies!!
Well done, not for first timers but still very good.
Thanks a lot 🙏🏼. In fact, this is extremely useful for people like me who don’t see Polaris.
Very nice way to explain things. Quite informative process.
Thanks for watching. I’m glad you liked it.
Thanks for this very good and understanding tutorial!!! You help me a lot.
Greetings from germany
Thanks a lot for your kind words. I’m glad that the video was helpful. CS!
Nice video, very well shown the procedures👌👌
Thanks! I’m glad the video is helpful. Cheers!
Nice video, one thing I’d like to mention, is balancing with the scope cover off, especially when it’s metal. It will make a small amount of difference
Thanks for watching 🙏🏼. You are absolutely right about balancing the scope. Just wanted to limit the video length and that’s why I didn’t include bringing the mount from under the shed and pulling out the tripod legs. Appreciate your kind advice.
Thank you from Malaysia!
You are welcome Joshua. I’m glad that the video was helpful.
Wowwwweeeeeee love. It but I wud pay more attention if u guide us abt wat we r looking. At !!!! 🙏🙏🥰🙃
Many thanks for the very good explanation video, i'll try as well to fix it withouit Polaris at my balkony :)
Thanks for watching. I’m glad the video is helpful. CS!
Thank you
You're welcome
Extremely helpful! I have my ASIAIR and first camera on order and I was wondering how i would do this with ASIAIR when Poloaris is not visible.
Thanks! I’m glad that the video was helpful. CS!!
Even with a ASIAIR it’s still a faff on, surely there’s got to be a easier way.
I understand. It’s not that easy when you don’t see the Polaris. Thanks for watching! Cheers!!
A good and helpful video, no frills, just a good workflow explained nicely. Well done, and please keep them coming.
I have a few questions/comments: does All Sky PA rotate the RA axis in only the Western direction? If so, then if you choose a sky to the East, you need to ensure that you have enough angular distance from the Meridian to eliminate the need for a Meridian flip. The corollory to this is that if you choose a sky on the Western side, then you need to leave enough angular distance above the site's horizon to ensure you don't have the last movement looking at a terrestrial target! (e.g. target within 20deg of the Meridian). In essence, you need to leave a good 40deg angular movement. Hopefully, the All Star PA is smart enough to determine which direction it should move from your chosen target, although it won't have knowledge of your horizon obstacles.
I have yet to get this to work. My only attempt resulted in All Sky PA turning off and presenting me with the standard pole PA procedure. I'll give it another shot, soon
Thanks! I'm glad that you liked the video.
In All Sky PA, the RA axis must be pointing North side.Then the mount/scope can be rotated initially in any direction, except due East or due West. And yes, ASIAIR will move it only Westwards (it is also shown on the PA interface). As you said, make sure it is well above the horizon so that the view is not blocked by a tree or house. Also, there is ample rotation space for the mount to move 40 deg. westwards. I have not tried or tested All Sky PA when the scope has to cross the meridian line. I'll definitely try this out as I mostly perform All Sky PA and post my results here.
Thanks again. CS!
Thanks for your feedback. I'll be interested in your results of your Meridian crossing test.
As I'm at 32deg South, it will have to be the SCP for me. I tried again last night to get All Sky working but it just turns off immediately I start the PA function. All I can think of is that I'm too far off my eye-balling the SCP with my compass that it just 'spits the dummy'. I don't really think this is the case, but I'm grasping at straws at the moment. I'll keep testing, but it's going to waste precious clear nights. Another thought I had is that for the Southern Hemisphere All Sky might rotate RA eastwards, and it detects that I'm too near the Meridian which it decides it shouldn't cross. That's 2 issues to check out tonight.
For the Main Scope Focal Length, do you enter what the telescope actually is without reducer or what it becomes with reducer? I've read somewhere that ZWO will figure focal length out and should just enter what the telescopes actually focal length is without reducer. Thank you. Nice video!
Thanks! I'm glad the video is helpful.
Reg the focal length, you may enter it if you know exactly what it is after attaching the reducer. Entering the original focal length would be wrong if using the reducer. If you are not sure, just enter 0 for focal length and the ASIAIR will figure it out. Hope that helps. CS!
Thanks for the video. When you say : after polar alignment, return home before using goto. how did you do that ? you unlock the clutch of the mount ? I have an starAdventurer gticand i received the asiair plus in few days. thanks.
Thanks for watching! No, you do not unlock the clutch when using the Go To Home function. Cheers!
great video and a new subscriber, i have a question when you move the scope for focus did you slew to it or unlock the clutches and manualy go to the star ?
Hi Frack, Thanks for watching. I’m glad you liked the video.
For focus, I usually skew to the a bright star using the hand control of the Celestron AVX mount. This rough focus helps in easy polar alignment. After this video, I added an EAF to my telescope.
Thanks again for the Sub and CS!
@@AstroCrescentDIY 👊👍
Great video and explanation. About that bright star deneb that you choice, did you used the sky map? And after focus did you start the PA while the mount was not in home position? But still on Deneb? I wonder how i can do this with my skywatcher EQ6-R pro.
Thanks for watching. You can choose any bright star for focus, depending on your location. I used the Stellarium mobile app to locate a bright star, which was Deneb when this video was made. Once this is done, you can keep the mount there or move to any part of the visible sky, so long it is not due East or West. Just make sure that the mount is at least 50-60 deg above horizon because the ASIAIR moves it down twice for PA.
@@AstroCrescentDIY ah ha, well I live 52 degree north. I found a star in stellarium that's on 50 degrees, Mirfak. If I choice for this the scope will only rotate and the mount not. Or Gamma Per that's 53
@@Stefan-Astro-Art Try it.
When we say ‘the mount moves’ that means the scope moves. The tripod is still roughly positioned towards North.
When you turn on your mount, do you have to complete at least a quick align, for the Celestron to allow control by the ASIAIR? Mine won't work until some level of alignment is done on the mount.
Yes, the mount should be pointed towards North and a Quick Align with hand controller is required. Thanks.
Great video ! I would like to ask if the all sky polar alignment button remains on all the time if we use the telescope in a place where Polaris cannot be seen?
Thanks! I’m glad you liked the video. The All Sky Polar Alignment stays so long as the imaging session is on. For the next session, you must recheck whether the alignment is on or not. Also depends whether you have moved the mount or not. Hope this helps. Cheers!!
@@AstroCrescentDIY Thanks🤩
thank for thhe video, do you know hoy i can align that mount, do you have a video with the betther parameters?
Thanks! You might want to watch this video. This may give you little more insight on alignment.
ASiair Plus All Sky Polar Align. No Polaris, No Problem.

Clear Skies!!
I just purchased a Celestron NexStar Evolution 6 with alt-azimuth mount and ASIair Pro. Will this method work for me? Polaris is hidden behind my house. Good SE exposure though.
Thanks for watching! Congratulations on your purchase!! Yes, you can use this method for polar alignment if you do not have clear view of the Polaris. All the best!!!
Wanted to ask, did you use guide scope as primary scope for focusing?…then switch over to main scope?…I have read in other posts guide scope is easier to focus
No, used the main scope for PA. You can use guide scope, but main scope is best for precise alignment. Thanks!!
Wow great feature ….how’s the tracking
My tracking on the AVX mount stays between 0.6” to 1.0”. Much depends on how good is PA and the mount itself.
Thanks for watching the video. CS!
Good video, thank you for that, I live in the South Hemisphere so I do not see our polar star. But I clearly can see the area where our polar star is, so my question: is this method good to polar align here in our SHemisphere? Thks for answering. Regards from Chile
Thanks for watching!! I’m glad the video is helpful. For sure, you can use the method for alignment. Just the stars would be different in Southern Hemisphere. Cheers!!
Thank you for answering soon 😊
I have an Celestron AVX mount and an ASIAIR Pro, I can not seem to get the ASIAIR Pro to connect to the Mount. I noticed you have no issue with the ASIAIR Plus. Can you help with some tips on how I can resolve my connection problems with the AVX and ASIAIR Pro?
Hi Joseph, Thanks for watching the video. There are a few things that you need to take care of. First make sure your connection is through the hand controller. Then -
1. Turn on the AVX mount before the ASiair.
2. After AVX, turn on the ASiair and let it boot up.
3. Enter ASiair on your phone/iPad.
4. Check the baud rate on the first screen. For me, it is 9,600 bps.
That should pretty much resolve the issue. If not, you need to research the topic on forums like Cloudy Nights, etc.
hope this info helps. CS!
Thank you
. i will give the procedure a go.
Start at 3:22 for the meat of what he said was in the title of this video, assuming you already know how to set up your scope. Also there's zero content in the audio, just music, so that can be muted.
Right.
hello, where can we find these alt and az buttons, thank you very much
Thanks for watching the video. The Alt and Az adjustment knobs are on the mount itself. All equatorial mounts have these knobs.
Thank you for your quick reply; I would have liked to change mine, which are not practical@@AstroCrescentDIY
Easier with Celeste on starsense
Right…Thanks!!
