oops, I see you have VP02-08 already.

1) the serial number of the mount
2) the direction of the oscillation (most likely RA I'm guessing)
You can send this to my e-mail direct and we can go from there: chris1011@...
I'll be leaving for Christmas eve dinner in a few minutes, and tomorrow we are not here, but I will get back to you first thing Monday. We'll get it sorted out. Probably a simple setting and also you may want to load the latest version P02-08 into the CP5.

I'm the dope who originally posted this on CN :). I wasn't specifically posting it as a problem. It was more like a "hey cool, this mount can track for 10 minutes at 2800mm without guiding!", and "here's what I did" post. I loaded more counterweights than the specs of the mount originally so I didn't think there was anything to fix. I do now... It seems that there is a some positions that if I slew my mount there, it goes into an infinite "oscillation" mode. I can physically see the scope move back-and-forth a few millimeters about once a second, and it will keep doing that even if I stop tracking completely. It stops though if I park the mount in that position. I'm running directly through the ASCOM driver v5.30.10 connecting via USB. (I'm still learning APCC). The mount firmware is VCP5-P02-08. The encoder firmware is A02-08. -- Roland Christen Astro-Physics -- Roland Christen Astro-Physics |

Thanks Roland,
I sent the mount info in email. The direction of oscillation is RA. |

Wow! Just setting it up must have been quite a chore. I suppose you have to wash dishes for a week after taking this picture. Merry Christmas to you and Marg and the rest of the crew at AP. Regards Don Anderson

Well, I couldn't resist. Here's a pix of the setup with the caveat of WHAT NOT TO DO!
It's a 155EDF on top of a 160EDF, each has CCD cameras and Quad TCC hand grenades. The two scopes weigh ... I don't really know. The goodie bag on the end of the counterweight shaft holds another 10lb weight because I ran out of shaft length. Total cwt = 3x 14lb plus 5x 10lb plus 1x 5lb. (yes it tracks and slews just fine, but a bit boingy if you bang on it).
I set this up to test the QuadTCC with the 155EDF scope for a customer request, but didn't want to disturb my 160 setup which I am using for a winter imaging project. Do Not try this at home upon pain of death from Marj!!! (my death mostly)

Ok, we'll get back to you and take a look at your mount.

Roland sets up something similar during the indoor final testing phase for each Mach2GTO. It is a bit of a chore, but has deepened his understanding of this mount.

Not sure whether or not I should post the resolution back here, but Roland was able to help me out, and it works great now without any oscillation.

BTW, it would be nice to also post on CN that the issue has been resolved. -Ray Gralak Author of PEMPro Author of APCC (Astro-Physics Command Center): https://www.astro-physics.com/apcc-pro Author of Astro-Physics V2 ASCOM Driver: https://www.siriusimaging.com/apdriver -----Original Message----- |
