Images like that make me want to sell the house and buy a solar scope It is definitely a wall hanger!

yes this Istar Optical lenses optimized for h-Alpha ( sphérocromatism optimized in red wavelenght) is very good!!!
I used for a long time a very good AP155 mm F/D 8.5 to make my solar images, but there we go into another world!!!
a image of my home made refractor on AP1200 GTO Mount
I am certainly going to build soon a 280 or 300 mm in FD 12 or 15 ( folded refractor)
the 230 mm works also well in lunar

A 300mm refractor.....that would be a veritable monster - even though some folks might think a 9"/230mm is already!!!

Pete the next 280 or 300mm refractor will be a folded refractor, thus less impressive
