Hopefully this is the right area to try and get some help with the AS-GT mount as I'm having a lot of trouble with the GoTo function being rather inaccurate and tracking issues that show up when taking photos.
I guess the 2 main things I need to know are (a) am I polar aligning correctly and (b) what my expectations should be for accuracy with GoTo. The mount has been factory reset, is running 4.21 firmware, the settings on the controller (date/time/location are all correct), the mount is positioned correctly (level, right latitude, etc.) and I've checked the polar scope itself is aligned as it rotates around a fixed point so I feel like the basics are there.
I'm not sure if I'm doing the polar alignment correctly though (no manual for the polar scope). I have the Celestron scope as below and have screwed it in tight to the mount but I'm unclear as to whether it should be facing a certain direction while the mount is in index position. From here I have no idea what to do; I've got an app (polar scope align pro) which shows me an image of the view through the polar scope and I believe I'm supposed to loosen the mounts right ascension lock and rotate it until the polar scope looks like it does in the app (or so Cassiopeia and the Big Dipper are correctly positioned as they appear in the sky), then adjust the knobs to move Polaris into the small circle. If this is correct then how accurate does the scope position need to be in terms of referencing the sky as it seems rather difficult to align in the dark. As a side note there's dials both next to the polar scope and the counterweight bar which spin but are marked with what I assume are angles (0-90) and 0-23 but can't see that they do anything when spun?
Secondly when I have the mount set up and try to begin the 2 star alignment process the scope will slew to the general direction but require significant adjustment, I'm unsure if this is normal and part of the mounts calibration process but once I've done this and try to slew to an easily observable target like the moon, planets, Orion nebula the scope will get me in the general area but still often need a sizeable nudge to locate it which works alright on objects I can see but being in a high bortle area it's seriously limiting what I can image.
I feel like the issue is definitely user error rather than problems with the mount as it has on occasion been very accurate, I just can't replicate this frequently so any help with where I might be going wrong would be appreciated.
