Just recently rejoined CN/astronomy after loooong absence (15+ years). I bought a Stellarvue 80mm Nighthawk achromat that came with an M4 eq mount way back in 2005, I think, and have been using it 3-4 times/week since last December (weather has been cooperating here in NorCal). So far it's been great- pretty much grab and go availability/convenience, and I'm getting reacquainted with the constellations, planets, various DSO's and even saw the conjunction of Jupiter and Saturn. Woohoo! That really rekindled my interest in skywatching, and having my son actually show some interest in astronomy too (he's a recent college grad) really sealed the deal. I hope this is something we could both grow into. I've added a few eyepieces and some filters, which has improved observing a lot, so it's getting addictive....
Anyway, I have a question regarding a possible telescope upgrade/addition. A friend told me he has a Vixen R200 f/4 reflector he wants to get rid of and wants to know if I'd buy it- so of course I said yes. It would be nice to have some extra aperture to zoom in on the faint fuzzies, so it sounded like a good opportunity. However, he has no mount - he already sold it. So I'm wondering if that telescope could fit the mount I currently have, and if so, what other parts would be necessary.
Also, he didn't get the coma corrector, which I've read could help with preventing stars from appearing like comets near the edge of the field, but I'm wondering if I even need it for now. Is it important for a visual observer, or is it primarily a concern for astrophotography?
Any help is really appreciated.
