Looking to buy a modestly priced APO doublet for hobby level astrophotography and grab and go. I've got a Nexstar 4SE for the moon and planets and have used a cheap Meade 80 Adventure Scope with my DSLR for prime focal shots of Andromeda, Orion, Pleiades, etc. using my Nexstar mount and wedge.
I'm looking for a modest upgrade for the astrophotography side of my hobby, and have narrowed things down so far to the Orion ED80 and the Sky-Watcher Evostar 72ED. Wondering what the pluses and minuses of each are? The Orion is a bit slower, and has a single speed focuser. The Skywatcher has a wider FOV and a dual speed focuser. My OTA budget is a hard $500.
At some point, I'll add an EQ mount. I don't expect to go any bigger on the scope, whichever one I choose.
Thoughts, please. Thanks in advance.
