Hello.

I am the current maintainer of Stellarium's Telescope Control plug-in.

If Stellarium receives the coordinates successfully, it should display
a telescope reticle somewhere. You can search for it in the same way
as for any other object (Ctrl+F to open the search box, enter the name
of the object).

I've fixed the checksum calculation. I had missed a XOR operator. :(

I've uploaded an updated test installer to the same place:
https://launchpad.net/stellarium/+download
Look for: stellarium-bzr4876-servocat-ultima2k-8-win32.exe

If it works, please test if it can slew correctly to objects in all 4 quadrants:
- RA < 12, Dec > 0 (e.g. Procyon);
- RA > 12, Dec > 0 (e.g. Vega);
- RA < 12, Dec < 0 (e.g. Sirius);
- RA > 12, Dec < 0 (e.g. Fomalhaut).

If it doesn't work: please find the file with the telescope log and
attach it to your reply. If the telescope number is 1 (if it can be
controlled with Ctrl+1), there is a shortcut in Stellarium's folder in
the Start menu that will lead you to the log file - "Telescope driver
log for slot 1".

Bogdan Marinov
