Quote:I recently got back into astrophotography and thought, what the heck, I'll try an Astro Physics mount. I saw that I could actually get a Mach 1 with no waiting list and the mount arrived last month. I outfitted it with the polar scope and put it on an Eagle portable pier.I'm sure I don't need to go into the whole fit and finish thing as it's A+++ as expected. The Eagle Pier is really nice and light and I've had a custom ATS in the past. This is better since it adapts to rugged terrain better and is a bit lighter and easier to transport.In the past I've been a Tak guy and I've got to admit that imaging f7 or below I never needed to drift align. I just used the wicked accurate Tak polar scope and it was off to the races!I managed to get out to the Julian Star Fest this weekend with the kids (It's a very nice Star Party by the way; thank you organizers!).Here's my impressions. The AP system is super easy to setup and align and visual performance was awesome with both a SV130 and a C11.Night Two gave me some heartburn with polar alignment. I was able to get my QSI583 hooked up and focused pretty quickly on the SV130 operating at f7. I had just used the PAL on the Mach 1 figuring I would keep the images below 3 minutes. I could barely get 2 minutes before stars started elongating imaging M31 and Double Cluster. This was unguided, but I want to see at least 3 - 5 minutes unguided being possible at this focal length. No PE to speak up when I ran some 10 minute exposures to see if the stars would wander.I guess it's time for me to actually learn how to drift align It's always looked so time consuming and hard. I guess I just want to know if there is any software or other aids to this process? I tried the quick polar align routine in the AP handcontroller and it worked pretty well but finding a star within 1 hour of Zenith is not the easiest task. Some waiting was inolved for me, around 20 minutes for Deneb to creep into position so my OTA didn't hit the mount on the flip side of the meridian. With a Tak I would have already had 15 minutes of imaging during this delay.I know everyone will chime in with autoguiding. Yes, I will autoguide, but I prefer to really know how to make the mount work right before correcting it.I have TheSkyX or the AP Handcontroller to control the mount. Any suggestions on software or methods that makes it easier to polar align this mount?Thanks in advance for any thoughts.BTW, the error would have been guided out very easily but field rotation would eventually creep into this which is why I always try to start with a mount very well polar aligned which just seems to lower the amount of problems and also eliminates the troubleshooting when guiding is not working well.T-Point? Plugins for TheSkyX? Any CCDSoft Solutions?Thanks!

But PEMPro next version 3 is supposed to work with ASCOM cameras so if your camera came with ASCOM driver, then PEMPro may work.
