Other than chromacors which seem to be hard to come by, is there any other cost effective way (under $700) to get an achromat to perform like an apo. I've read about violet filters and understand that they don't do the job.
I have an etx 105 now which I like although for the right price I would part with it to finance a refractor.
I don't want to go higher than a 120mm refractor because of portability issues.
What concerns me is that I don't want to spend the $ on the refractor only to have 120mm of clear aperture lose out or even equal (due to chromatic abberation) the views of a mak 105 which has a central obstruction.
Thanx so much guys. I really appreciate all your constant replies even if I don't send it to each of you directly.
