ASIair: Add a "GoTo Zenith" Button

paulchen

Hi,
when doing Flats with a flatfield box, you have to go to Zenith to place your flatfield box onto your telescope. In the moment you have to manually move your telescope into this position.

Please add a goto button to ASIair GUI to directly move the telescope pointing to Zenith. That should be very easy and will be a great help.

Thanks,

paulchen In the moment you have to manually move your telescope into this position.

Scroll the GOTO coordinates in ASIAIR so that RA is equal to the current Local Sidereal Time, and Declination is equal to your latitude. Then issue a GOTO from ASIAIR.

Choose an RA that is slightly smaller than the LST, or slightly larger than LST, to choose which side of the pier you want the OTA to be positioned to do your flats.

4 minutes of RA corresponds to 1 degree of tilt; so you can ignore the seconds field of the RA.

Be sure to turn off Tracking after the GOTO. Almost every mount will turn tracking on after it receives a GOTO command.

ASIAIR only supports Right Ascension and not Hour Angle for its "Favorites" objects. Otherwise, you can simply set a favorite object as one with the declination equal to your Latitude, and Hour Angle of 0 hour (the definition of Zenith). Allowing HA also lets users park the mount on a permanent pier to any position the user wants.

Thanks for this workaround. But a simple button "Goto Zenith" would be the easiest way to make the flats. NINA and other sequencers offers such a button and it works fine there.

A good way would be to place a "Goto Zenith" button in the mount settings dialogue where you can still find the "Goto Park position" button

paulchen I forwarded this to our ASIAIR team, they will consider this in the future

Still no "Go To Zenith" button/ option after all this time. FYI: This should work, functionally, like Go Home does. I.e.: when you press it, it slews to Zenith, and keeps tracking turned OFF.

One thing when implementing such a "goto Zenith" button: the plate solving should be deactivated for this goto, because sometimes you do the flats after sunrise, so platesolving wouldn't work. Maybe offer toggling it on/of via a checkbox
