NGC 3501. The other galaxy at the top is NGC 3507.

Hi, David: That is truly cool! What’s the edge-on galaxy in the field? Eric Baumgartner Redding, CT USA From: Astro-Physics GTO users group <main@ap-gto.groups.io> on behalf of David

6 hours and 20 minutes.

Very cool. How much clock time does it cover?

Awesome and thanks! Send it to NASA! Jeff

I realize this is not exactly something that hasn't been done before, but it's the first time I've tracked an asteroid and made this kind of video. The Mach2 definitely made it easier than it would

Are there any users out there with absolute encoder equipped mounts who set up and take down their rig every observing session ? If so, what has been your experience with the absolute encoders ? Are

Hi Paul From what I can tell, the Allen head in the clamp looks like the head of a standard 1/4-20 socket head cap screw that has been press fitted into the recess hole in the aluminum clamp. The

Thanks, Ray. I did try to select "none" for the backup connection but the setting didn't "stick" when I reopened the program. I must not have saved the settings, or an earlier version was being

Hi Marty, First, if you don't have a COM port connected to the mount, you should disable the backup connection by selecting "None" in the "Backup Port" drop-down list. This will keep APCC from

Hi everyone, I'm running a Mach2 with APCC Pro, TSX Pro and SG Pro all interacting. It has worked very well with one exception: I get intermittent and (to me) unexplained loss of communication to the

If an allen bolt unbonds from the knob, I find the safest way to loosen a knob that is beyond hand tight is to use a strap wrench. The strap wrench is the astronomer’s secret weapon.

Thanks cytan.

Thank you, that helps.

It's no bother.

That’s OK no need to bother, so long as I do not need to buy anything else, I’m OK and will figure it out with hardware in hand. I didn’t mean to sound like I did not believe you, trying to

The back of the 1100 itself. I will get you a photo here in a few. 🙂 I use the Losmandy HD and the 119FSA which is basically what the adapter you showed is.

Like you, the bolt came off and the knob got stuck. I then had to use pliers to remove the knob. To get the bolt and knob back on DOVELM, I had the knob threaded loose on DOVELM, held it with pliers

That’s good to know, and I just saw the detailed “what’s included” list shows the CBAPT”. Good. But that it attaches to the mount is a bit at odds with page 16 of the CP4 manual, which

Release with Allen key. It's tight enough that I can't release with my fingers. cytan
