Connect asiair to the mount. Use the HC to go through the allignment ( use last allignment). Do the polar allignment with the AsiAir. select a star in the AsiAir and let it plate solve. Haven't tried it a lot so maybe I was lucky it worked.

First off I looked to make sure I had removed the cover :) then found I had heavy dew that had completely covered both lenses and I didnt have my lens heaters with me believing that I wouldnt need them :( Still baby steps but PA was great and pleased to have conquered the first crucial element of astrophotography.

I would like to see your experience with the unguided polar alignment video alongside a guided - to see at what point you can shoot unguided (2 minutes in your video) vs how long you can do the same guided. Would turning guiding in have helped reduce the egg shaped stars in your 2 minute sample photo. And how long could you shoot with a rough polar alignment and guiding turned on comparatively.

Hey just one hint: star alignment is not necessary at all and skipping it safes you a lot of time and hassle! Just use “quick align” and then connect the mount to the AsiAir. When slewing to the first target for example via sky safari just plate solve your position and then click “sync to mount”. After that the mount “knows” where it is really looking (usually not exactly on target yet) and you can again perform another goto maneuver to target. Usually then I’m perfectly centered on target already! With AsiAir after finishing polar alignment my rig is ready and on target In usually

Quick Align or Last align makes my guiding awful. Once I started doing a one-star alignment my guiding substantially improved. It's almost as if the ASI Air wasn't star tracking when star-tracking was enabled. I just do a generic one-star alignment and then immediately plate solve after. That gives me the best results.

lcxt9 We will see if I can get around to it. I’ll probably wait to the new RASA adapter comes on and then get on that.

Great presentation. You deliver the concepts very clearly. One point not covered. When setting up your scope to point at the celestial pole, it is critical that your Declination is set PRECISELY at 90 degrees. I have seen instructions that describe how to do this. Once set at 90 degrees, view the celestial pole and rotate on your Right Ascension axis. The star field should pivot on the center of your field of view. If this pivot is not perfect and is even slightly off center, you are not truly set to 90 degrees and your polar alignment will never be accurate. I have a flip mirror and a low power eyepiece in my optical train to make this operation simple.

I have bought the device but there is some kind of dense aqueous material that is hampering my observational abilities. Enjoyed this video. The one thing I have to do differently is when making azimuthal adjustments on the CGX, I have to loosen the 4 base screws just a bit so that the mount will move when turning the azimuth handles.

excellent!!!

Very helpful!!!!

Really good tutorial. I have an Orion mount with a polar alignment camera, but using the ASIAIR and a ZWO primary camera, I can do it the way you have demonstrated and have everything synchronized within the ASIAR work flow. Great Job. I also noticed that you have a RASA, so you don't have to waste time photographing all night ???

well done

Don't get esxcited, just because you get 0.0 and a rating of starship captain. Don't just press "finish". Leave it for a few minute, then hit "refresh", odds are, it will differ, as it does not take into effect your drift. I would suggest repeating adjustment, and refresh a few times - just my 2c worth.

Great video, really helpful. Im a bit confused on how the ASIAir knows when the telscope is adjusted during the PA. I have an iOptron Skyguider pro which doesn't have go-to controls, will the PA still work on the ASIAir even without Go-to or will i still have to use the optics on the mount to PA?

I’m a big fan of the ASIAir Pro and its been flawless in managing my sessions, except for PA feature! I’ve tried repeatedly to PA, without any success (with an AUX and EQ6R mount). Will follow your video - step by step - and see if I can achieve what you’ve done so easily in this great video. My question, after PA, do you turn mount on? I’ve seen folks keep the mount turned off, manually rotate the 60 degrees, do the PA adjustments, then turn the mount on and complete a single star alignment. Thereafter, in the single star alignment step, plate solve and synchronize to the mount. Then, do a test go to on an object, synchronize and then set! Given that I’ve never got PA to work for me, I use PolarMaster in lieu of ASIAir PA. Again, thanks for the great step-by-step video - best I’ve seen, and will try again to get PA working. With your RASA tube, would like to see how you use the Live feature - I’ve got the C6/C8 setup with HyperStar, and haven’t attempted a Live view. Looking forward to the release of “auto focus” for my refractor mono/filter sessions with the ASIAir Pro. AstroIowa

Sounds like we have different problems! I polar align the mount completely, and then I move the mount back to the switch position (index marks). Once that is done, I do a full star alignment (2 primary + 4 calibration stars). It is incredibly easy to do. If you’re polar aligned first my alignment stars are usually right in the FOV, no finderscope needed. Why don’t I do the plate solve then? Well the ASI Air behaves a bit weird with my Celestron mounts. I plate solve, and then sync it with my mount, but it usually fails, not sure why. I’d love to be able to just do a one star alignment, plate solve and be done, but it hasn’t been working so far. I haven’t toyed around with the live view mode yet.

You are simply using the main telescope optics and no polar scope, right? So the plate solving basically can do polar alignment on any star, not necessarily Polaris, right? How far away from Polaris can you venture and still get good polar alignment using ASIAIR PRO and this "approach"? I ask because I cannot see Polaris in my backyard.

Hi. When you are doing the polar alignment, does Polaris have to be visible, or does the ASIair use the plate information to deduce whether you are aligned? In my preferred observation place, Polaris itself is blocked by a few very tall pine trees, though most of the rest of the sky is ok. It was not clear whether the "target" of Polaris in the adjustment phase was actually Polaris or the calculated position of Polaris.

I'm wondering if this apparatus would work with pmc-8 system from Explore Scientific? Or would it be necessary?(seeing as they already have wifi & app for smart devices)

hello, if, as in my case, I look from East to South, can I use the polar alignment function of the zwo AsiAir? Thanks

How does the device handle dew, is it resistant at all?

EDIT: This works. So... I have the asiair and I have used the PA feature. But haven't used the PA feature when I'm shooting from my usual spot (balcony). Because I don't have a clear view of Polaris from there (there is an overhanging roof, and I'm only just missing out on Polaris). But, when I rotate the RA axis to about 30 degrees, I do get Polaris in view of my scope.. so.. (haven't tried this yet, but will do next time, but perhaps someone can answer me already) would I be able to do this; Can I start the PA with the first shot taken with my RA at 30 degrees. Then rotating all the way to 90 degrees for the second shot. And then complete the Polar alignment from there... so instead of 0 and 60, you do the PA at 30 and 90... I'm trying to think if this makes any difference to the accuracy of a polar alignment? because you're still rotating around the same RA axis.. so.. it should be the same?? and shouldn't matter where you start the first shot of the polar alignment, as long as the second shot is 60 degrees rotated from the first one.. right?? obviously after the PA I would zero out the mount again and do a staralignment/plate-solve from there. I'm only talking about the polar alignment here.

@kwitee

Having written software to do this method back in 2014, the 60 degrees should not be specially important. Anything more than 30 should be enough at a pinch. I don't know how ASIAir calculates the horizon line in your image (it may be using the date/time and GPS location from the app). Once you figure out if there is rotation between the suggested movements of the app and the actual movements you do with your mount, you can compensate for that and zero in.

James Dougan If you’re pointing to your pole and are able to plate solve then you should be good. Plate solving determines where the pole is at. As far as simplicity, the PoleMaster wins without a doubt. I love my PoleMaster but haven’t justified using it lately due to the ASI Air PA feature. I find the ASI Air more accurate for PA since it continually narrows your FOV and lets you get things even tighter. The PoleMaster is still great though.

One of the AAPs key features is target alignment (plate solving) which is labeled within the Telescope Settings tab as GoTo Auto-Center. Make sure you enable that. When you first start out, before you polar align, position your mount to the index marks, where it is pointing at the NCP/SCP (home position on the CGX), and hit the "Sync to Mount" button within the AAPs Telescope Settings tab. This will lock this position in as the home position in the AAP app. Now do your polar alignment. After the PA is complete, to test that the initial sync worked, you should be able to go back to the Telescope Settings tab, hit the "Start" button for the GoTo Home Position option, and see the mount move back to the index marks. This will confirm that the AAP and mount are synced and any Goto will be extremely close. The AAP will clean up any errors in the GoTo by automatically confirming and centering on the target via the alignment feature. Again, It does this automatically if you've enabled the GoTo Auto-Center feature.

@@wadeprunty awesome, been searching for this for a while now. Having problems with the home position. Home on Asiair isn't home on the mount. Thank you very much. I know, it's a stupid mistake, but sometimes you're overlooking the most simple things.

Some People say it is not easy to connect the Celestron Mount to the ASIAIR. Is that true? It seems to wrk good at your mount?

Does this mean I can use the software to align even if I'm on a south-facing balcony on the northern hemisphere and can't see Polaris?

Can any one tell me what Guide Scope model that is?

How to pa on Celestron Alt Azm Mount

I may be wrong, but an Alt-Azimuth mount can't be polar aligned, no? It doesn't have an equatorial wedge... I know that it's possible to use a Sky-watcher AZ-GTi in EQ-mode, but then you have to load some unofficial software onto it...

I’m genuinely interested in the ASI Air, but seeing you use the polar alignment and achieve an error of zero, then take an image and see elongated stars and suggest that you could perfect the PA more, how can you improve on a reported error of zero?

I have a Polemaster. Reading reviews of the Polemaster allignment vs the ASIAIR PA it seems like the ASI does good enough if you are using tracking when you shoot but the Polemaster is superior. My guide camera decided to crap out during the only good day that we have had so I cannot say what the proper answer is right now.

Hi Cody, Do you have the ASI air Pro connected USB to the actual mount HC or to the hand control at the bottom. I been trying to find a cable that is USB to the 6 pin to HC on the mount connection to get rid of the hand control.

I plug my mount into my ASI Air when I’m done Polar Aligning. You can do it before if you want but it’s hit and miss. Sometimes it auto rotated 60 degrees for me. Other times it goes crazy and doesn’t stop. So I just manually do it when I use the ASI Air PA, but it’s up to you.

May I ask, using the QHY Polemaster is quicker and does not lag. is this just an alternative for those who does not own a QHY Polemaster? Or will it be more precise doing PA with this method through ASI Air Pro?

The ASIAir Pro acts as an all in one astrophotography computer. You can use to to polar align, autoguide, slew to find new targets, control imaging sessions (like switching out filters), etc

The ASIair Pro uses plate solving. @ 1:15 you mention "before star alignment ", Why are you still using star alignment?

Polar alignment and star alignment are completely different beasts. PA makes sure your RA axis is pointing in the correct physical direction and any star can be tracked by just moving one axis. But the "brain" that does the GOTOs still does not know where anything is ( that depends on your location and time/date for a perfect telescope). By trying GOTOs to known stars, the "brain" makes a model of how your telescope flexes and bends so the more GOTOs and platesolve+syncs you do, the better the next GOTO will be.

so you are setting up to polar align with your main imaging camera

Hey after polar align and the mount is at 60 degrees do you put it back to the index marks and then go to your target?

I have heard both sides of this question but to me it seems that a perfectly level mount is unnecessary. both axises that you track from should be on the same axis even if the mount is not level Polar alignment is the same in either case.

Hi John. If the tripod is not level, then the centre of mass of the mount head/telescope/camera/guidescope unit will not be directly above the midpoint between the feet of the tripod. This is true, even if you've balanced everything in both axes ( Right Ascension & Declination) & polar aligned the mount. Since the tripod/mount/scope/etc system is extremely top-heavy, if the tripod is sufficiently out of level, it is possible that the entire set-up is closer to what engineers/physicists call its 'tipping point'. In the worst-case scenario, strong gusty winds hitting a large telescope with a large dewcap could lead to disaster, however the much more likely problem would be a less-stable set-up that could be more sensitive to gusts of wind & ground vibrations. Furthermore, with a tripod that's not level, one or two of the legs would be bearing more weight than they should, so there's the risk of them sinking into the ground more than the other leg(s) as the evening progresses, ruining polar alignment without you knowing it's happening. Now, IMHO, the tripod would have to be a long way from level for the set-up to be significantly easier to tip, and the ground would have to be soft for one or two of the legs to sink & lose polar alignnment. Nevertheless, the difference between having a set-up that enables you to get round stars in an image (therefore maximum signal/noise ratio) and a set-up that will give you elongated stars is miniscule in astrophotography, so IMHO, the issue of decreased stability & greater likelihood of vibrations is worth worrying about. Consequently, I would suggest that you get the tripod as level as you can (it doesn't have to be absolutely 100% perfectly level) in order to maximize the likelihood of getting the best quality images possible. I hope this was helpful. ☺

@@derekbaker3279 I appreciate the info. I stopped leveling my mount after not noticing a difference, but I always set up on a pretty level surface. Maybe I will for now on .

Levelling your mount is not necessary for polar alignment. When you get your first unguided shot, plate solve it (do you get an indication on the image which way is North?) and see if the elongation of the stars is in the DEC (S-N) or RA (W-E) axis. If it is in DEC, your polar alignment is still off and needs to be improved, if it's in RA then polar alignment error is not your limiting factor and it will be nicely guided out.

Nice tutorial, thank you. Just a quick point, you state right at the start that it's super important to have a level tripod/mount. That isn't true. You could mount your tripod to a wall if you wanted to and as long as the head was accurately polar aligned you'd see no tracking errors.

Hi, yes, true, but the problem is getting the polar alignment in the first place. If the mount has indexing mounts or an automatic zero position then it needs to be level to make use of that feature. BobUK

I don't think an unlevel mount will give tracking errors, it only makes it slightly more difficult to polar align because the alt az adjustments won't do exactly what you expect. Once the Ra axis is parallel to the earth, it didn't matter the orientation of the rest of the mount at all

@rogue277

@@wadeprunty I don't see how that could be. If mount is not level, you can still bring the RA into polar alignment with the alt and az adjustments. At that point, as long as the RA axis rotates at the sidereal rate, then it'll stay put. The worst thing a nonlevel mount would experience is slightly more adjustments getting polar aligned with the alt and az adjustments.

@@wadeprunty You are wrong. As long as you mount looks level, you are good to go. All that matters is whether your RA axis is pointing in the right direction. Now, if you have a set position for the tripod on solid ground and have made marks on the ground and want to take the stuff indoors and set up the next day quickly, then yes, use the bubble to get a close starting point from last night and avoid doing the PA again, that might work well enough (you can check quickly enough). But if you are goint to be doing PA anyway, the bubble can be off by a few degrees and it won't make a difference.
