Han - I did not know 0=automatic!

Stash - this is not the software, I'm sure.

Jerry - thanks for that! I think you nailed it as that is exactly the scenario.

Last night, I had quite a bit of success, but also an annoyance. ASTAP generally solved in seconds, and reslewed the scope to center the object, and I was very happy *except*:

ASTAP more or less centered Vega, but it also failed to solve once Vega came on screen. I told it to try again and this time it solved. But it never put Vega dead-center and instead left it a bit high.

ASTAP would not center M20 at all. Even when I changed the accuracy threshold to 10 arcsec, it placed M20 at the edge of the frame. As such, I was unable to image M20 - a good thing really - I needed to get more M16 data anyway. But it was odd nonetheless.

ASTAP centered M16. I set up for 100 60s shots w/dithering. Somewhere along the line, M16 drifted down in the images. I attempted to recenter but ASTAP said it was within tolerance.

I did NOT try any other platesolving.

Any idea what setting I might have wrong that would cause all this? Likely candidates?

Thanks a bunch and clear skies!
