150mm F5 refractor or 100mm F6 refractor?Posted By Parri Munsell |
I'm in the market for a 2nd portable scope and have my eye on the Skywatcher 6" F5. The Skywatcher is a very rare beast and I'll have to get one imported but might be worth the pain considering you get 150mm in a 31 inch / 16 lb tube.
My delema is whether I buy this scope knowing there will be a lot of secondary color or whether I go for a higher quality 4" F6 such as the Burgess Optics model.
Primary use would me the Messier objects.
So the question is:
Higher quality 4" or lesser quality 6"?
Any and all opions welcome.
