I tried my first ever attempt at building an automated pointing model using APPM. (I've used manual T-Point runs in the past.) The plate-solves were all failing. I must be doing something very wrong h

From the archives a while back there was official talk that a mobile app like Sky Safari would be able to communicate with the mount via APCC. Was this ever achieved or did the idea get abandoned? Tha

I have an 1100GTO mount on order and plan to house it in an observatory on permanent pier with imaging in mind. I own an old AP 8" diameter portable pier. Would anchoring this in concrete and filling

I’m trying to generate a pointIng model. I’ve done this before with no problem, but I have a new computer, and I’m having issues. Please see the attached. What are these RA (topo) and Dec (topo)? They

I know others have had good luck with unguided imaging, but we just got the first clear and stable night in Southern California in what seems like months, so I was able to try out my latest APPM model

Ray, When is the Dec arc tracking model coming out in APCC? I would like trying with my AP1100 Thanks Max Mirot

Don Love it – dem’ was the days of real computing, unlimited memory, and engineering hard drive. Yours looks like the famous, highly desired ... K & E Log-Log-DeciTrig-Duplex “slip-stick”. Engineers w

Hello All, Alas, a recent ISS passage and the ISS tracking questions pour in. :-) I guess this is for Ray. Tracking ISS yesterday with APCC / Horizons / AP1200 worked reasonably well. Video from the A

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

Okay, I'm trying to use A-P's Horizons to track the ISS, and I have a couple of questions. I was able to get the ephemeris data from JPL and load it into A-P's Horizons. So I have data loaded in there

My Mach2 is all set now for APPM. Just waiting for a clear night. The next slot looks to be Saturday through Monday but the moon is out (46% on Monday). Is it practical to run APPM with the Moon out?

I use SkyTools 3 and SkyTools 4 to control my AP1600 mount using the ASCOM driver. But every 6 months, I was having to switch the AP keypad from standard time to daylight savings time and then back ag

Hello all, Is there a way to play with APCC and JPL horizons without mount connection to practice for ISS? I mean some way where the software emulates the mount and allows me to run the JPL ephemeris

A new poll has been created: I am toying with connecting via ethernet to save a USB space on my control computer. I have also ordered an FTDI serial adapter to try that out. Therefore I should only ne

Having used sky safari pro on my iPhone for a while I have decided I want a larger screen. Which iPad would you recommend for use with Skye safari? Best, JimP Get Outlook for iOS

I want to get a hard copy of the APCC help file, and since it is so many pages I would like to get one of the local printing services to do so. The help file is copyright protected, and the reputable

I have an older AP1600 mount that does not have the quick release option for the RA and Dec gears. Is Astro-Physics going to release an upgrade kit for older mounts to allow for quick un-meshing of th

If you have an APPM model and a Tpoint model in The SkyX and use TSX as the planetarium of choice, what takes precedence? And is there any way to force one or the other? Shailesh

If the pier or tripod clears the scope and imaging train, approximately how many minutes/hours would an AP1100 go past the meridian? Shailesh

Hi Ray, I was trying to build a new model for my AP1100 tonight with APCC Pro v1.8.8.17 via SGP v4.661 and a QHY 268M camera and APPM was giving an error message "Failed to connect to Camera: cannot C
