I use the A-P ASCOM driver <https://www.astro-physics.com/ascom> on my 1200, and it works fine. Ray Gralak, the developer, is a regular on this list.

The driver GUI has NSEW buttons, and you can set the slew rate right there on the same screen. I use the buttons often to center a planet or the Moon when I want to make a "movie" for later processing. Normally I use ACP automation software, which connects to the mount via ASCOM.

I can connect SkyX to the mount via ASCOM even if ACP is already connected. This means I can monitor in SkyX where ACP is pointing the mount, or I can slew the mount in SkyX if ACP is not actively imaging.

In my experience, ASCOM is a wonderful interface, and the A-P driver is great.

Rolando,

I received confirmation from Software Bisque that there is indeed a problem with TSX causing the JOG button runaway.  They will fix it in an upcoming interim release.  In the mean time, they told me to avoid the JOG buttons or perhaps try the ASCOM driver.  I don't know much about ASCOM except that I've not had good luck with it in the past.  Does AstroPhysics provide an ASCOM driver for the AP 1200 GTO?  If so, where can I find it, and where can I get information on installing and using it?  Thanks for your help.

Excellent info.  I have a TEC140FL on order and have been planing on using the QTCC and either an APS-C or a 4/3' sized CMOS chip with it.

Roland,

Have you ever done a ray trace of the QuadTCC for the older AP 130 EDF F6 ( oil spaced) ?
Some of us would like to know if it is likely to give acceptable results at full frame.

Thanks

I am having an issue with my Mach1GTO mount that I suspect is caused
by an incorrect configuration of time zone offset due to daylight
saving time. The problem I am getting is a very inaccurate GOTO and a
counterweight pointing upwards upon parking (I always park to Park 4

the option "Manage Sites" I get a Time offset of -2.0, when the

(Brasilia, UTC -3), however we are not under daylight saving time this
year in Brazil (exceptionally) and I think this is causing some issue
with the way the mount is behaving. I can see that APCC is applying
daylight saving time as "TRUE" so that the offset it is sending to the
mount is UTC-2.0 instead of UTC-3.0, however since we are not under
daylight saving time this year in Brazil this may be causing some
confusion?....This has not happened last year when we were under
daylight saving time. Can someone help?

Thanks!  I love the ~1100mm focal length image scale/fov, and the slower focal ratio doesn't hurt at all with these CMOS cams that take such short exposures.  Do I wish I had an f/6 version also?  Sure! But I won't trade this f/8.35 away for anything.  Years ago with my old SBIG ST-8 and a narrow H-A filter, I'd have to shoot 15-20 minute subs, but since the mount tracked so well, who cared!

By all accounts that's an excellent image. How do you like the longer focal ratio of F8.35? That scope was made when F8 was considered fast. We have become somewhat spoiled since those days.

Hey everyone,

Just wanted to share a shot of M82 showing how well my AP900 handled the 130mm f/8.35 during an unexpected (to me) wind storm last week. Not a great image compared with many on here, but considering the flying tree branches, it turned out well.

I stupidly forgot to check the weather before setting up on a clear, dry night on the back deck.  What I didn't realize was that a rather large wind storm was bearing down on the SF Bay Area later that night.  I woke up to a gust that my weather station recorded at 29 mph, so in a panic I ran outside to see if everything was ok.  Mount seemed find, and to my surprise it was still guiding and the subs looks rather good.  Fat bright stars from the bad seeing, but otherwise the wind didn't see to be affecting anything.

Image located here: https://www.astrobin.com/ix35g6/?nc=user

I bought my 900 new from AP back in 1999, and not an imaging session goes by without me marveling at the quality and ability of this mount.  It's newly upgraded with a CP4 and APCC Pro (the CP4 had to go back for a warranty fix of some internal component, and I'm happy to say it's back working flawless again). APCC is worth every penny, as the tracking and pointing models are a fantastic upgrade from my old CP2 box.
