Question about Meade ETX-90 (48x90 mm)
My telescope has started sticking when slewing left,it stops and makes a clicking noise,can you help
Some (not all) versions have an end stop - it it just reaching that? The scope will rotate only aboit 3 complete turns between the 2 ends.
The 'correct' starting position is as follows: Place scope on tripod or table with control panel at the West. Unlock the declination lock (horizontal slew). Rotate scope anticlockwise until it hits the end stop, Then roate it back clockwise until scope is pointing North (should be about 3/8 of a turn, as the end stop is at South West). Then lock the declination, Set the tube horizontal and continue with the alignment process.
Autostar always thinks you have set the position like that. If you haven't, it will work OK until it tries to rotate past the point it won't go, then chaos results!
