Allow for setting mount limits

jdain

The other night while imaging the heart nebula, my mount proceeded way past the 90 so the counterweight was above the scope. The mount kept tracking until the scope hit the tripod leg and broke my EAF. Please add the ability to set limits where one can allow the mount to go x degrees beyond the 90' limit and check this while tracking to prevent gear damage. I've seen this functionality in other systems like EKOS and it is very useful to save expensive equipment.

jdain. I think the ASIAIR can be set for meridian flip right?

I have had the same problem. I am testing now with no other controller connected to my skywatcher Mount and it is just gone about 15 minutes past work should have flipped. This has to get fixed.
The first time I tried an auto run with the meridian flip it worked fine. It has not worked since.

Were you targeting an object that is passing the Meridian between the pole and the Nadir? (I.e., a circumpolar object that is passing the part of the Meridian that is closer to the horizon -- northern horizon if you are in the northern hemisphere.)

ASIAIR only recognizes the half of the Meridian that runs between the two poles and passes through Zenith.

When you set up AutoRun, look for a line of data at the bottom of the AutoRun setup window (and also the main window when AutoRun is active) giving the time interval before a Meridian flip. If there is no such info, you have encountered the bug. ASAIR will not stop tracking at the Meridian. Don't let it proceed, since it could lead to a very expensive accident.

A Meridian limit would not have helped, since ASIAIR does not even know there is a Meridian line there.

This bug has been reported a while ago to this forum, but I have not seen an acknowledgment yet from ZWO that it is a bug, nor when it will be fixed.

No, I was not between the pole and the Nadir. I think I've figured it out. 2 issues. I had not turned the flip off on the mount (I sure I didn't the early time it worked) and (biggy) daylight savings time had to be turned off on the tablet as well as the mount.

Interestingly, iOS turns on DST automatically depending on country and locale (it does not turn on in Arizona, for example).

Anyway, DST will come on for many of our friends in Europe this coming weekend. There will be others who missed my warning post and will get hit by the bug in three... two... one... :-).
