I did a long imaging run last night with the Dec compensation off with a 600+ point APPM model active and Dec Arc tracking on. I was also using the Beta PHD2 version with the bump tracking feature. Th

Don, I own one, but have only used it with an RST-135E. It works as advertised. One of these days I'll try it on my Mach2. Just be aware that StarAid is pretty much a one-man-show. Hendrik, the owner/

I agree it was a good explanation of declination compensation. The question was if this option is relevant if an APPM high density all sky model is operating. The model would account for the variation

Did a search and couldn't find any info on this. If using an APPM tracking model (with Mach2) should the "Use Dec compensation" in the PHD2 advanced Guiding option be on or off? This is not the backla

And mirrorless 😉

The new StarAid version supports dithering with certain cameras.

Bill, I’ve had this Mach2 since Dec 20 but have only now tried a full sky model since I’m not in an observatory. Ive had the TOA130NFB a bit longer. It used to sit on a Chinese mount until I found A-P

Yup, with a fish scale and IAW the A-P balancing instructions in the Mach2 manaul.

A fair question. All 8 clutch knobs were tightened slightly more than hand tight with a hex wrench just before I started the model tonight.

Now you’ve seen one 😉

It’s just their 4” focuser version of the 130. Heavier than yours but not by a whole lot. It’s definitely front heavy, but I’m anal about the balancing. Size wise it’s on par with your 130GTX. Also, i

Fair enough. I'll get back to you later tonight.

And for completeness, the load on the Mach2 is a Tak 130NFB, stock focuser, CFW3-L, QHY268M with a UPBv2, Baader Vario guide scope in an A-P mount and bracket with the A-P Tak adapter. Also a FlipFlat

Based on the position the OTA was in at that time I think Dec. I'm not at all a master at looking at trails and determining which axis it is occurring in. Attached is the image from the dec -15 failur

When the model is complete I'll slew back to that region just to see if the mount is tracking correctly there. I can't find much information regarding what exactly a slew warning entails other than th

Started at 2x2 4sec. Also tried 2x2 3s, then 1x1 3 and 5s just to get some troubleshooting data. All full frame. It’s only showing trailing at the 3 points that fail, repeatedly regardless of settings

I see others have had similar issues in the past. I'm doing a full sky model for the first time. I usually just do dec arc models before a run since I have a semi-permanent setup. I'm seeing odd behav

It didn’t for me. Everything works fine.

Same here. Down to -15°F without issues. All L-com USB3 cables other than one USB2 to a FlipFlat. Remote from yard to house with an ICRON 3104. Front Range in Colorado so very low RH. Eric
