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

Last night I was imaging with my QSI683 camera through the AP 130EDF on my Mach1GTO and had an unusual thing happen. I was on my last subframe of the evening, at around 2am and suddenly I noticed that

APCC pro and PHD2 are used to control all mount movements during my sessions. I was imaging Saturday March 13th into Sunday March 14th, in the eastern time zone. My session continued through 2AM and t

I've seen many comments about the ability of AP mounts to slew to a counterweight up position with the scope on the east side, so that you can avoid the flip and continue west. Assuming I want to trac

Thinking about purchasing an AP 600 E GOTO for visual observations of double stars with my AP 155 F/7. Everything about the Mount sounds good except the seller says it has significant declination back

Altitude at park 3 should be 47 degrees. Site is correct. This happened before, not sure what the problem is. Wayne

Having finished my re-greasing, which involved removing the motors, I had to redo my PEC. I ran 6 worm cycles in PEMPro last night and generated a PE curve this morning. In the workflow PEMPro says to

I set up the meridian limits using APCC last night, and I have to say that it’s a very useful and easy-to-do process. It’s one of those things that you can read about, but you really need to do it to
