Flatener / Reducer
Hi
I have a APO 115mm, 805mm Focal length, F7 refractor, the place where I purchased it from is offering a matched Flattener / Reducer for aprox $600.
I'll be hooking it up to a ZWO 1600mono.
I see there are cheaper F/R available, the dealer I bought my scope from says his is a matched pair.
I feel I can spend less on another brand, do you think it imperative to go with his suggestions?
Or would a generic F/R for my scope be ok? Multi coatings etc taken in to consideration.
Thnx in advance
O
