We recently purchased the afore mentioned telescope and I need some help
to decide if it is malfunctioning. When using the 2x barlow lens and a
Super Plossol 9mm Meade eyepiece, how big should Mars look. I was
looking at Mars the other nite and the best I could do was to make it
appear about the size of a pencil eraser. This doesn't seem right. Any

Mike here: That sounds right. Mars is pretty small after all. But you should be able to make out some surface markings and perhaps a polar cap.
Subject:	Wanted ETX 90 "flip" mirror

From:	Mike K (
I am trying to locate a replacement "flip mirror for my ETX 90 EC.  The
coating on mine is starting to peal off, and it is out of warranty.  I
only need the mirror, not the entire assembly.  If anyone has one, or
know of a source that's not overpriced, please let me know.  1/10 wave
or better is sought.
