My observatory is under the flight path from L.A.-area airports to the southern states (AZ, TX, FL). With the current Covid-19 shutdowns, there's been very little air traffic. It won't always be

Oh! I guess this is something possible under the Autosave tab, which I rarely use. I use CCD Commander for 99.9% of my imaging, and it tells MaxIm what settings to use. Could you get a similar

Nudge guiding is done while the mount modeling is adjusting the background tracking rate. Both RA and Dec axes have to move at a different rate than sidereal in order to accommodate atmospheric

I'm baffled as to how you do this.

Ed, You may wish to contact me directly. What control box do you have (CP1 or CP2) and what is the chip that is in it? If you have a Windows PC, you may wish to use it. There are mixed

Mike, I agree that satellite’s or planes are more likely to show up in long sub-exposures. However, shouldn’t these trails go away when you stack your image using the median of each pixel or

I don't want to spend an hour on a single image that a passing satellite ruins in an instant. I too have made long exposures for testing, especially when I was tracking-down flexure), but my for-real

Nothing says that you have to do 1 hour exposures. I do it for test purposes and because I can. My 160 refractor can take some temp changes without changing focus. If your scope is more finicky, then

Lovely shot. The only problems I have had with 1 hour subs is temp change, resulting in focus change during the long sub-exposures or running into the dreaded "mount flip" before the exposure is

Hi All, Just posted my new project of the Bubble nebula region. This first image is just the H-a portion to which I will eventually add OIII and SII for a narrowband color image. The exposure is 8

Anything over 20 minutes would be guided. However, it is "nudge guided" with modeling running in the background. This is the most accurate way that allows the mount to move at a smooth custom rate and

Hi Ray, FYI. To your point #4, no need to find one. Recall that there is a Windows provided off-line memory test – under START->ADMINISTRATIVE TOOLS –> “Windows Memory Diagnostic”.

Are these guided or unguided 1 hour images with APCC Pro and the Mach 2?

Hello, The Mach2GTO and the 1100GTO are both in production at present, and each has a notification list. We do not know how many people on the notification lists will actually purchase a mount,

What is the difference in wait time for the 1100 vs the mach2 ?

Rodolphe, Also, can you use APCC's log zipper to zip your logs and place them in the files section, or post a link to a dropbox or other folder? -Ray Gralak Author of PEMPro Author of APCC

Hi Rodolphe, Your info indicates the crash occurred in ntdll.dll, an operating system DLL, which means it is not actually APCC that caused the crash. Windows potentially is out of date, or

Hello Yesterday evening I experienced a mount crash; when SGP command issued to park the mount at the end of the session, apparently APCC crashed. SGP log and Windows event viewer follow below. Please

Hi - After a 18 year hiatus, I am returning to amateur astronomy. I have a AP1200 mount running keypad firmware V3.06. Starting things back up, the keypad battery was dead and I replaced it. I wanted
