Hi folks. With all respect, it would really be better to ask questions about PHD2 on the PHD2 support forum. A fair bit of what's been talked about in this thread is off-the-mark in terms of how PHD2

Hi Tony. If you'll post your guide log on our PHD2 support forum, we can probably help you figure out what's going on. https://groups.google.com/forum/#!forum/open-phd-guiding Cheers, Bruce

Hi Leo. If you'd like to post your PHD2 log on the OpenPHDGuiding forum, we can help you figure out what's going on: https://groups.google.com/forum/#!forum/open-phd-guiding I agree with Roland, it's

Good to know - this explains some of the "write-only" behavior. Might be good to add that explanation to the documentation on the AP command set... <g> Bruce

I kind of doubt it. According to the published AP command protocol, there's no way to read these values from the mount firmware. You can only set them. There are actually quite a number of these "writ

Hi Suresh. One of the computed values in any plate-solve is "position angle", which determines the angular position of the camera relative to the stars. As long as you have a reference image showing t

The log shows the calibration was near-perfect. PHD2 does a bunch of sanity-checks on calibration and generates alerts when things don't look right - none of that happened. I suspect there's a non-zer

Hi Anis. I think you're posting to the wrong forum, the folks here aren't very familiar with PHD2. If you post your question over here: Google Groups Google Groups Google Groups allows you to create a

Hi Henry. I think you should move this conversation over to the OpenPHD2 forum as Andy suggested. Your last 24-minute guiding session showed a tracking/guiding RMS of 0.77 arc-sec with nearly equal st

Hi Bill. There's no rocket science involved if you follow the PHD2 recommendations. Use the new-profile-wizard to create a new profile for your mount with the correct system parameters such as camera

Hi Geof. You are probably going to like the mount a lot, and guiding with PHD2 should be a piece of cake. Here's what I would suggest: 1. Install the latest ASCOM platform and the AP ASCOM driver - bo

Interesting. Fortunately, I can say I don't go there. <g> Bruce

Thanks, Rolando. If you could use the dropbox site, that would work better for me. That's what we use for guiding-related analysis on the PHD2 forum, and people seem to have no trouble with it. I'm in

Hi Rolando, this is pretty impressive. Since you asked, can you provide an un-binned raw luminance FITs image suitable for plate-solving and statistical analysis? Thanks, Bruce W.

I think you've got too many cooks in the kitchen here. I would say it's pretty unlikely this is a problem with the mount or with PHD2 for that matter. The PHD2 log files will likely tell us what we ne

Hi Suresh. If you aren't able to quickly figure this out, why don't you post your question and the associated log files on the PHD2 forum: https://groups.google.com/forum/#!forum/open-phd-guiding You

Hi Dean. I'm just making a guess here, but I think Maxim 6.09 added a bunch of stuff for slew and tracking limits in the observatory tab. In that case, Maxim could be issuing an 'Abort Slew' command b

Hi Daniele. I’m oneof the developers on the PHD2 project, and I was interested in thispost. It wasn’t clear in your message,but for the “perfect” guiding examples, Dec guiding was disabled altogether.

You didn't say what kind of scope you're using. But this is a common thing with off-axis-guiders on scopes like SCTs. The shape you're describing sounds like coma or some other off-axis aberration. Th

The guide settings should mostly depend on the guider image scale (arc-sec/px) and the seeing conditions you have. With high-quality mounts, the mount will have little to do with it. Bruce W.
