As recommended by Roland, I was able to eliminate the worm play on both axes by adjusting the backstop. I also had a talk with Howard to clarify some details re. the DEC axis and greasing. Thank you

I've been away from my email for much of the week. Is this still an issue? There was a recent update to both NINA and the SMF plugin, so be sure to have those installed.

It's not entirely clear what your full APPM configuration is, but here's what you should generally have: 1. Make sure your local copy of ASTAP is updated 2. In NINA, make sure Enable Server is On 3.

Hi Linwood I used to mount my 180 EDT scope while the mount was in Park 3 until Roland suggested that having the mount in Park 2 makes it much much easier to mount the scope. He was right. The best

Assuming you are using NINA for the image capture, do you have the telescope information entered in NINA (Under Options - Equipment)? Maybe ASTAP needs the focal length in the FITS header for the way

So are you using APPM to control the camera? It sounds like that may be a difference. I only use NINA to control the camera, could not get APPM to work well (camera is too large I think, or ZWO’s

APPM gives you full control over ASTAP's settings, You can thus misconfigure settings. If you see lots of failures, send the failed images to astap's author. He's the best person to explain why a

Linwood, Dean, Brian - thank you for sharing. It could well be something in my settings. Just odd that failures on invocation from APPM seem to happen much faster than from SGP where it tends to run a

Have you tried updating ASTAP to the latest version?

NINA does not expose an interface for external applications like APPM to invoke its plate solver. So have you looked at the failed images to see what they look like? APPM just runs the ASTAP

WORKED on it all night - giving up. I couldn't get APPM to work with ASTAP. Oddly - another solver in APPM setup is "SGP"? That's now a solver that's a program like NINA setup with a solver.

I have bought different AP dovetail saddle receiver plates over the years. Never had this kind of problem with any of them including the discontinued models 🤔 Fernando

Fantastic detail, as usual. Eric

I wrap the mount in a big beach towel and secure the towel with a couple of short cargo straps wrapped around the mount as it takes up less space in the back of the car. I pick it up at a couple of

If you don't use PEC then the stars will wander back and forth by the amount of the PE error. So you will get an oval star image in the RA direction. Roland

Amazing! 😎 Pete

When using Dec-Arc tracking for unguided imaging I presume that using PEC is absolutely necessary and that using the mount's native periodic error (ie no PEC) won't give decent results. Just

Thank you Ernie, can you post a picture? Shailesh

SEtup but still light out. I clicked this test button. I loaded a APPM pic from last night and it loaded and solved under 3 seconds. All I changed was bin from 1 to 2. I'll try live tonight and

Linwood I agree, I've never thought there to be an issue and do like you do it. tony
