Skywatcher 150 refractor question (non ED)
Just wondering if anyone has used one and if so, how much CA did you experience?
I've seen one fairly cheap brand new (about half price) and was thinking about it, but I don't know if the CA would annoy me, or if I can get a filter to mask it a bit.
Any thoughts on the matter would be great!
I've never really used a refractor before as I've been a reflector person all the way. The last time I looked through one was in 1995!
Cheers
Tim
