Feature Request: Polar Alignment

Post by timfromma » Sun Sep 09, 2018 3:05 am

I know that ASIAIR utilizes PHD2 for autoguiding. It would be extremely helpful if it also utilized the PHD2 polar alignment feature. I still need to bring my laptop for polar alignment but it would be really nice if ASIAIR could take care of this too so I can go truly laptop free.

I second this request.
A precise PA would obviate the need for guiding on fast scopes.

Hi Sam,

Any news on this? It shouldn't be difficult to implement since the source code is freely available on Github!

Do let us know of any updates! I look forward to the day I won't have to take my laptop with me solely so that I can run SharpCap polar alignment routine and literally switch on, PA, switch off and be done in 5 minutes...

+1 for polar alignment routine as done by Sharpcap/Polemaster

I'm not nuts about the method of polar alignment in PHD2 (basically a form of drift alignment that takes time to refine).

There are other methods that are faster and more accurate. SharpCap Pro and PoleMaster both use a method where you rotate the mount in RA while a camera tracks the position of a star. It fits a circle to the star to find the center of the RA axis ... and then puts a point on the screen showing you where the center of the axis *should* be if it were properly polar aligned (and you adjust the mount via the mechanical knobs). This is faster and more accurate than what I've seen from PHD2 (which tries to determine if you're having a persistent drift to help refine the polar alignment).

KStars/Ekos uses a plate-solving method.

While I like the PoleMaster camera and I like the software concept ... I find QHY's implementation is a bit clunky. The software crashes a lot. They finally produced a version that crashes "less often" but it still has bugs (for which users have identified work-arounds). It's been several years and they still haven't fixed these bugs (and they do know about them). I use the mac version, but I've had issues helping my friends who are on the Windows version. Great idea ... clunky implementation. (THIS... btw, is the whole reason why I own a bunch of ZWO gear. I found QHY's software support was poor and realized I shouldn't be buying any more gear from them if I can't rely on the software to work correctly.) In contrast ... ZWO has been awesome!

These systems work better if you have a more generous field of view (e.g. 5° would be great ... and it really should be more than 1°).
