CG5-AGST general alignment frustration
Posted 06 October 2012 - 02:56 PM
Never had this problem in the front yard...
Anyone else ever experience this nutty behavior with their CG5-AGST? I am running the latest firmware... If I can't get it to work better tonight, I am just going to move it to an even worse part of the yard where at least I get a glimpse of Polaris... Ugh!

Your 2 star + 4 star alignment has nothing to do with polar alignment. If you don't have the RA axis close to the polar axis, you're going to have to move the mount. Compass apps in cell phones prove to be unreliable. Get a real compass or find some other means of more accurately pointing the mount to the north before you start your alignments. Once you have started your alignment you can not move or re-level the mount. You can move the mount in AZM when doing your ASPA, but try to keep your movement to a minimum. Do not re-level the mount and do not release the clutches.

I had a hellava time aligning my mount after I bought it and it wasn't until I started over and made a couple changes like those above. Another thing to be aware of and I'm sure you are is balance, I believe thats important too.

I also got to where I would get started on alignment at dusk so it is way easier to find the stars it is looking for incase it was off because that way only the bright ones that it wants you to use are visible.
I don't have to do that anymore since I have been sitting this thing down long enough now that I can sit it down even in bright daylight and have it pointed almost directly at polaris just based on the surroundings. With practice it will get that way for you.
I would go where you can see polaris and get your bearings so you can pretty much tell where it should be even though you can't see it. I say that because depending on what part of the country you live in magnetic north might not be really north when compared to polaris.
Good luck and again that behavior is normal when the mount it placed on the ground way off in comparison to when it was last precisely aligned.

A couple of months ago I downloaded the HC and MC update tools from Celestron and upgraded the firmware on my mount. I no longer need to perform the factory reset, so it seems they have exorcised that particular bug.

My 30-degrees off was fixed when I re-did the motor calibration. Once you're aligned, you do it, and it will program the mount for the weight of the scope and the final slew to target.
"motor calibration"???? Where is that in the menu??
