Mikko, I can't tell from your photo what is wrong with the mount's position. It looks close to park 3. And as I mentioned before a plate solve/sync will offset the coordinates so a return to Park 3 wi

Hi Mikko, Have you checked the mount's polar alignment? Also, maybe the scope is mechanically or optically misaligned with the mount's RA and Dec axes which will cause pointing errors. Maybe you said

Hi Mikko, The difference between LST and RA is called the "Hour Angle" and will vary depending on where the scope is pointing. Hour Angle is 0 at the meridian, which is the imaginary line running from

There doesn't appear to be any logs that cover the time at which your image was made according to the images FITS header which interestingly says was taken at 4:42 am, which is one minute *after* you

Hi Michael. The link I provide just now is not to the apcc installers but to the nasa web site. They are entirely different things. -Ray Gralak Author of APCC (Astro-Physics Command Center): https://w

Hi neyle , I have no idea why it would not open on your computer. It is probably related to a problematic Windows update. However, here is the link: https://ssd.jpl.nasa.gov/horizons.cgi#top -Ray Gral

Even if the mount *is* well polar aligned there can be pointing errors from other sources. Once you plate solve+sync that will change the relative position of the Park positions. I think you just didn

Hi Mikko, The part that I think needlessly worried you is that after a plate solve + recal you expected the mount to return exactly to the marks where it started. If the plate solve + sync changes the

Hi Cytan, I don't think it matters, but I would use the second way. You can have APCC turn off tracking after unparking from the Park tab if you don't want tracking enabled. The option is a checkbox c

Wayne, I can't help you with SkyX Pro crashing but you might want to make sure you have the latest daily update installed. Also, you may have done this but as it says in the help file: "TheSkyX Pro Im

APPM can send a command for SGPro to take an image with SGPro's camera. Things like binning, full or subframe dimensions, and duration are passed to SGPro. Later, after the image has successfully crea

Hi Mikko, After you recal/sync the mount via a platesolve and return to one of the park positions it can appear to be in the wrong position under certain conditions such as: * The pier/tripod is not p

Park 3 is on purpose not exactly at the celestial pole, but close. So, that's okay. It seems like unparking from last parked position has solved the problem, correct? It's always safer to unpark from

When the mount is first powered on it will report RA=0 Dec=90. This indicates that the mount needs to be initialized. That's what your screen shot of the driver shows. Initialization is the process of

Hi Cytan, They use different libraries. APCC uses the .Net framework and the driver does not. I'm guessing this is a .Net Framework issue. -Ray Gralak Author of APCC (Astro-Physics Command Center): ht
