I finally tried out my purple U.S.A. ETX90 the other night. Had to mount it on top of my Bogen 3050, which made the balance a little funky. Probably would work better if I’d put the quick release plate in the back hole instead of the front. I’m thinking of making an L-bracket to put it on my SLT.
I had previously removed the sagging baffle from the meniscus, and all seemed well. Collimation was spot on.
Anyway, I just went out with the Baader 8-24 zoom in it. And it seemed to cover the range that I needed pretty well. Easy enough to zoom out and find stuff. The scope is pretty easy to point.
Image was good on Jupiter and Saturn up to the 156x that I had available. Next time I’ll take my 5mm LET out and give it a little more gas.
So far, I like it better than my F/11 C90, which needs a tweak on collimation. And I’m kinda digging the built in eyepiece holder.
But the finder is pretty useless, and prevents the zoom eyepiece from being fully inserted. So maybe I was a little above 156x ?
Still I’d like to try a bit more power. Details on Jupiter don’t match my 6 inch achro at similar power. And no real hint of the Cassini. The terminator of the Moon is also ho-hum at 156x after seeing it at well over double that.
Maybe ho-hum is a little too harsh. I really love how small and easy to use the scope is. I think a C5 is in my future for the biggest little scope. But I’ll probably hang onto the ETX anyway.
