Hi, This is probably a dumb question but can all you AP refractor sages opine on what the likely difference is between
the two Stellarvue refractors below.
1. SVX130T Premier Apochromatic Triplet
2. SVX125D Premier Apochromatic Doublet
First the obvious,
a. Slightly different objective size, 125mm vs 130mm
b. APO doublet versus APO Triplet
c. Both SVX, therefore
c. both have superb strehl numbers (0.98-0.996)
d. $2595 vs $4995 !!!!!! Whew
From reading the descriptions it seems like the main difference in cost comes from the extra Lanthanum optics element that purports to deliver "color free, high contrast performance".
I realize that the 125D is mainly meant for visual observations while the 130 is an AP instrument.
But, my question is If I added a field flattener reducer to the 125D and the same to the 130T what would the difference be in the resulting AP images? I know this is a rather subjective and ambiguous question but I'm trying to figure out why anyone would pay 2x the price. Would AP images be that much better?
