Achromat vs Mak
Currently have a SW 4" f/10 achromat and have been looking at possible upgrading to a SW 127 mak.
Wondering whether it would be an upgrade of sorts, with a little more aperture and more ergonomic and compact for transport.
Basically my question is, would a 5 "Mak be an improvement on an 4 " Achromat of similar aperture ?
