Hi,
I set the correct location for my backyard obsy, but I noticed each time I set up the longitude setting is different on settings screen compared to the main planetarium screes, see 1st image below

Secondly when I start my mount on home position, the DEC reading is always near to 90 degrees, 89 or so, but the RA i thought should be on zero for home...but it never is, see second image...

Any ideas of reasons for these discrepancies...??

1st) there is a difference in representation. One shows the longitude in degrees, minutes and seconds and the other in decimals. 1° 52’ 59” == 1.883056°

2nd) the Right Ascension is only exactly 0 if and when the telescope is rotated accordingly. I guess that you have your telescope pointed at the north celestial pole with the telescope directly above the mount. When it is positioned like that, it will point at the RA that currently is culminating south.

The objects that are passing through the south meridian have a certain RA. This is what the mount points at when aimed at the borth pole in rest position.

I actually just updated KStars to display in sexigesimal format instead of double in the location info box. Small detail, but I guess less confusing for users

What is a 'South Meridian'? I know a 'meridian' and an 'anti-meridian', depending on whether it passes through the zenith or the nadir, respectively. I am not aware of a distinction into north and south?

You’re right. The meridian is the line passing through the poles and the zenith and that’s what I meant. I added south in the hope to clarify things but that was wrong. Thanks for the correction!

So is this update in the latest version of Kstars, or a seperate update...??

If you're talking about my change, it would be in the next version for Longitude/Latitude representation. For the RA/DE differences, you are comparing two different things. The EQMod screenshot for the Alignment tab, it is not the current aligned position of the mount which is found under the Main Control of the EQMod driver.

Ok, got that, so in normal home position (scope up and weights down) what figures should I expect to see in the main control tab for RA/DEC...?

Dec should be 90°, RA whatever is passing through the meridian at that moment.
