Are the batteries flat?
Is the cable properly connected to the scope? Unplug and reinsert both ends.

Won't hold co2 at all when cartridge is installed, all co2 comes out instantly

It sounds like the check valve is stuck open. Also, the seals may have either become twisted or torn. An internal inspection (also known as a tear down) is in order. Check with the manufacturer's website for instructions and/or assistance.

Need instruction manual for 1996 or 1997 etx 90 basic model

The manuals are all available to download from

If your scope has the motor drives and a control panel into which a controller could be plugged, then you just need to buy an Autostar 497 - always available on eBay for about £85. However, there are older models of the ETX which only have one motor or as a spotting scope for terrrestrial use with no motors - Autostar cannot be connected to these.

Look at the pictures of scopes on eBay which come with Autostar - if your looks like these, Autostar will fit. Else you are out of luck!

"F-EE" indicates that the camera cannot take automatic control of the lens' diapraghm. To resolve this, turn the aperture ring on the lens (the one nearest the camera body) to the largest number (probably 22 or 32).

Meade etx-80 sticking

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!
