Hi Stash.
I went a bit drastic really.I totally wiped the PC clean,and one by one carefully re-installed all the programs.
On opening APT i went into the Tools tab,and carefully entered my camera,and Focal Length,in the object calculator.Becareful here if you are using a focal reducer.When the camera connects it recognises the camera and auto inputs the rest.
I decided to go down the ASTAP route,and downloaded the correct files,including the star database.Extracted to the C:/ drive.I also installed Plate solver 2.8 at the same time.
With ASTAP ticked in the point craft settings,i slew to an object my chosen target,took a 10sec image,and asked it to Blind solve,which it did very quickly.I then hit Sync,re-enterd
the co-ordinates next to the Goto++,and then hit Goto ++.
It slew to target and centred.
I,m hoping i have cracked it.
Mick.
Of course you dont have to wipe you PC clean,but as i only use mind for the obsey it was,nt a big deal.
