I use an A-P portable pier, and I set up and take the mount down every night, I only use the RAPAS for polar alignment, Mike I am impressed that you can take the scope down every night and use RAPAS

That won't be a problem. You don't need to turn off tracking rate correction for autoguider calibration. -Ray

Hi Joe Great suggestions about using tape to mark out setting circles. I may give that a try. I used pencil to make the marks because I wanted to be able to remove them if necessary. The pencil

George & Shailesh Good point about the holding screws. For some reason I seem to recall reading in the mount assembly instructions that they did not need to be installed if the user was planning to

Thanks Ray! Another question......what kind of problems might i see if i accidently left the pointing model running during a camera guiding calibration and running of pempro? I think i had a

Hi Dave, The initial dec tracking error is probably just dec backlash runout. Until the backlash is taken up the dec axis wasn’t moving despite the non-zero dec tracking rate. Regarding pointing

sorry for confusion......AP1200. I understand that the APCC pointing model not only improved pointing but helped tracking according to Ray. I experienced it myself after creating a pointing

Not a goto mount but my mid 90's 600E stepper motor hand controller has an intermittently sticky north button. Any suggestions on how to fix it? Taking the cover off the controller it seems

Mike, Are you referring to the silver knobs under the DEC plate? If they come lose do you not have holding screws? On a side note: do you have any tracking or balancing issues with the 180EDT? Is it

Hi Mike, Nice job on your pencilled setting circles. I was thinking the same thing about perhaps AP providing “stick-on-tape” setting circles as visual aids for their mounts, as an option.

The Dec axis doesn't track. There is no tracking in Dec, only the RA axis tracks at sidereal rate. Do you mean Dec Guiding by any chance? APCC pointing model does not set custom tracking unless you

Notice something new with my autoguiding, Maxim DL,APCC pointing model setup upon initial guiding during startup. thereafter it doesn't happen. The DEC axis tracking error grows up to about 2-3

Submit to APOD!!!! Peter

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

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
