Effectively speaking, AP mounts don't lose their sky alignment
when the power is removed, unlike Meade, Celestron, iOptron,
When being powered up, AP mounts know precisely
where they were pointing when power was removed. The only thing they don't
know is the current time/date/location, etc. and wait for an external PC or app
or AP hand controller to tell them.
However users that are not familiar with how AP mounts work,
might be over-complicating their lives with incorrect
When power is restored to an AP mount, it knows precisely
where it was pointing when power was removed. In a permanent setup, simply do a
GOTO to some object to confirm pointing.
If you pointing is off after restoring power, you most likely
have an issue with OTA ortho, OTA/focuser/attachment/camera flexure, mirror flop
or polar misalignment.
If you are using both a PC and the AP hand controller, there
may be issues with slightly different time/date/location data between the two
I hope this helps.
Permanent - thanks
I'll download and try
it. I thought I had things worked out then I made some adjustments on the
scope and now alignment is off again. Guess I can try to check ortho issue
if I find the easiest method from up that high to do it.
Permanent pier or temporary setups? If it is permanent then you only need
to align once after the first setup.
Ortho error might be making your life more complicated. Evaluate it and
Besides all-sky plate solve, some people put a tiny refractor on their
main scope with its own camera. This can help with pointing confirmation and
remote alignment recovery.
All sky plate
I recently put my C11' on a mount about 11 or so feet above the
ground. So, using a finder scope to center an object after slewing
from parked position 4 is no longer practical. If the object is not
on my software screen, I'm lost and I have a very narrow FOV at
f/10. What is the best way to approach this problem?
