I've currently got an ETX-90RA (90mm by 1250 focal length) that I really like but I know it is limited and I'm starting to get the itch for something better.
So, I'm at the fork in the road of what to go with next. I've seen some reasonably priced Dobsonian and moderately priced Cassegrain scopes.
I know size is the major difference with Dobs needing large tubes for the higher focal lengths. Just looked at a Zhumell Z8 that only has a 1200 focal length. Is that the equivalent of my ETX-90? Should I look for a 10"? I know a larger objective allows for higher magnification lenses and barlows.
Would it be worth the price to just step up to an ETX-125? I have a good selection of camera accesories for the rear port of my ETX-90 that will work on the ETX-125.
Or should I look at a 6" Cassegrain?
Thanks in advance for any information to help guide me.
