Here's a little lesson learned tidbit that I just discovered on my 1100 mount: I have been noticing lately when setting up the mount with my 180 EDT that there is some play in the dec. axis. I thought

That is one nice image of Jupiter! Thanks for posting Roland

Back then I almost always did 20 minute exposures. Roland

I’ve got one of those original AP 10” F/14.6 Maksutovs. Great for lunar and planetary imaging also. AP 10” Damian Peach, Dave Tyler, Jim Phillips Get Outlook for iOS

Just match pixel size to focal length. High qe camera helps too. Some of the new backilluminated cmos cameras allowing binning would be excellent. J Sent via the Samsung Galaxy Note9, an AT&T 5G

“BAM!” 😎 Pete

Wow that is one heck of an image! Do you recall any exposure times, even overall?

Wow! That's incredible Roland.

With the lousy weather this February I decided to reprocess a couple of images taken back in 2011. Can't get decent skies this week or next according to long term weather outlook. This image was taken

Thank you, Roland, best regards to you and your team at AP.

Polar alignment error is compensated when you make a model. I can't answer your 15 - 20 minute unguided imaging question. Rolando

Thanks, Roland. Is sub arc minute level PA sufficient (both AZ and ALT) to do unguided imaging (say 15 or 20min NB) with standard AEs? Shailesh

Clutch settings have no effect on polar alignment. It may affect the model to a small extent, so I would try to return the mount back to the original position after doing a manual adjustment of

Thank you, Jimmy and Jeff B. I was able to use JImmy's tape trick to determine the direction of rotation. For those who have AP1100, the right AZ knob turns the mount clockwise while looking from

Hi again, OK, solved it! Your hint about ASCOM triggered some thoughts. Uninstalled V2 driver and APCC. I reinstalled ASCOM which fired up a warning about Ransomware protection which is not compatible

Hi Ray, found it, 0 bytes. Don't know what happened :( I have renamed it and proceeded as you suggested. I keep running into the same issue (Driver connects directly, now with the updated firmware);

Thanks you Jimmy and Ray ! @Jimmy I keep in mind the delay, couple with tracking limits that is one solution. But first I'll try yours Ray, thank a lot for your answer !

Hang in there. The 1600s are in production now with delivery later this year. Clear Skies, Marj Christen Astro-Physics 11250 Forest Hills Road Machesney Park, IL 61115 Phone:
