You didn't answer my question. Which axis is showing the error? Roland

Ray, Ah, so I shouldn't use "hour angle", I can try that. I tried pointing corrections on and Dec Arc off, seemed better. It looked like Dec arc made it worse but the object still moves. Some subs

Here is another blink clip of the previous nights tracking with a model with less points. I believe its not a flex problem as its very

Can you tell me which way the image drifts, RA or Dec? Roland

Rouz, Unfortunately, I think the "Hour Angle" point ordering strategy may be the problem. Because the points are not collected in a declination-arc it is way more likely to be subject to random

Hi Roland, My camera orientation is 90 degrees and the image downwards mostly but at a slight diagonal. I have made a short video clip in the

Hi Ray, Yes I used "Hour Angle" with APPM. I closed APCC, I'll open it again and see if I can create that zip file now. Thanks, Rouz

Did the target move in RA or Dec? Roland

Hi Rouz, Thanks for the details! Could you also put a zip file created using the APCC Log zipper utility? Please include all the APCC, APPM, and ASCOM logs from the evening when you were doing the

I'm very happy that V1.9 now works with NINA and ASTAP. Model building was very straightforward and quick. For some reason, my unguided exposures have trailing stars. The target will move a few

Neutral balance. Rolando

If the scope flips to the other pier side, it counts as a new set of two dec arcs of 5+ points (20 total sky points minimum, 10 on each pier side). -Ray

Ray, are you talking about at least 5 points to the point where you do a meridian flip or 5 points horizon limit-to-horizon limit including meridian flip? -- Dean Jacobsen Astrobin Image Gallery -

Good info. Thanks.

You want at least one Dec row of mapping points 1 degree above and 1 degree below your target. Each row should have at least five sky data points. You can define more points per arc for additional

I usually set up and tear down every time I image, and I tend to do only one target in a night. What is the most efficient way for me to do mapping and still get excellent results using dec arc

Same thing happened to me. My virtual ports were 21 and 22 and now there gone. My primary port is now com 3 which also switched. Virtual ports as option 21-23 are no longer available as options.

David, I sent you a private email, but I wanted to post here as well in case anyone else has a similar issue (unexpected parking) in the future. In looking at the logs you supplied yesterday

APPM does look at the FITS header. The only thing I can think of is that there is another FITS header keyword that it is using. APPM doesn’t just pick numbers out of a hat! J > Even so, you
