Re: APCC move axis question

Andrea Lucchetti

Can you remind me your mount type?
About one year ago I saw something similar in Skyx but I thought was because the mount was new ( Mach 2). After that I learned to use the move commands in appc and I don’t know if it has been fixed. In my case the move click in Skyx caused a perpetual slewing that I needed to stop in appc. I didn’t use any model at that time.

That's a fair point, but really steps around the core issue.

As a simple example, the NINA control panel has simple N/S/E/W controls.  These stop working when pointing corrections are active.  I have no idea if there are other places in other programs that also use move-axis.

Should these in fact be failing when pointing corrections are active?

I just tried a trivial example:

- Opened APCC, initialized (tracking = 0), pointing corrections disabled
- Opened NINA, connected
- Using NINA control slewed N, then S - worked fine, fast (APCC showed it slewing)
- Checked pointing corrections
- Slewed N, S - no motion.  Only thing I saw on APCC (or maybe ASCOM V2) was flickering from custom to sidereal rates as I pushed the button

This itself is hardly an earthshaking issue since I can just use the APCC controls to slew (if my sleep deprived brain can remember in the wee house), but it does bring with it a concern that other features of NINA or other software connecting via ASCOM my not work.

Or is everyone pretty sure this is a very isolated case and nothing else uses move axis?

Or are you saying that Move Axis itself, if allowed, would break the pointing model?
