ETX-90RA. I originally used this for a piggyback scope on a 12" LX-200 but no longer have that scope. It has only been out about ten times or less.


RA drivebase with 3 fresh AA batteries and tabletop tripod
26MM Meade 4000 Eyepeice (excellent condition)
Optional right angle finder (exc condition a couple of screw marks)
Original straight through finder (couple of scratches on the front - optics fine)
T adapter
Kendrick Dew Shield
Original Box

The primary mirror has a few miniscule (can't even see it unless the tube is apart and inches away from your face) where the secondary shroud came off and barely touched the primary. It has been secured to the front glass since.

There is also a small area around the secondary on the inside that has a little haze (about 1/8" concentric around the secondary shroud) Did not want to clean this as it is likely in the shroud shadow anyway.

Neither of these affect optical performance in any way. Views are very good as are most of these Muskatov Cass's are. Tube is clean and free of scratches as well as drive base.

One of the battery terminals had a slight corrosion from an old set of batteries- this has been cleaned and motor function verified.

Last thing is the metal screw cover on the back is missing (have looked everywhere for it - used to use the port in the back piggybacked on the 12") I have put on a rubber cover that fits very tightly. If I find it I will put it with the scope)

Bottom line if you are not satisfied return to me (minus shipping) and I'll refund your money.

Great Starter scope and extremely portable.

Price includes shipping in Lower 48

Thanks for looking
