I'm in the research phase of getting a refractor and could use some feedback from experienced folks. This will be my first refractor and the main use will be double stars. No photography. I'm looking at achromats as the bang for buck factor is kinder to my limited funds. Portability is a major concern as well due to my 74 yo back (no dobs.)
After reading every online review that I could find I was leaning towards a Sky Master Evo Star in 90mm or 102mm but the the Vixen A81M and A80mf caught my eye.
Having read so many reviews on different scopes that said replace the diagonal,finder etc etc is the quality of the A81M such that it's good to go as is, therefore almost as cheap as a lesser quality outfitted scope when the dust settles?
So if I am limited to one scope, with optical quality, finance and portability as main concerns is the A81M the way to go?
Thanks in advance for all the advice.
