I'm pretty much a noob to astronomy, I've had a few inexpensive scopes in the past but plan to give it another go now that I have the means to get some relatively good equipment. I decided I wanted as large of an apochromatic triplet as I could get for under five kilobucks. I picked the 130mm apo currently offered by Stellarvue and I sent Vic a $500 deposit to get my name on the list for the next batch . Then I noticed that the specs page for all of the apo scopes on SV's website list the ED glass type as FPL-53, and their quad astrograph uses FCD-100, both glass types have an Abbe number of 95. The specs on the 130 just say "ED center element" searching through some forums I discovered this is FPL-51, which has an Abbe number of like 82 and everyone seems to agree that scopes with FPL-53 or FCD-100 are noticably better than those with FPL-51. So now this scope, that I am about to pay an additional $4200 for (scope flattener, FT focuser, diagonal and hard case) is gonna be worse than the new ES-127 carbon fiber with FCD-100 which costs about $1500 less! And maybe the next batch of SV 130's will have FCD-100 like their quad does. What should I do??! I'm freaking out!!
Thank you for any advice!
