Hmmm... food for thought. I briefly considered the 120mm f/8.3, but again the dreaded CA monster scared me away. If you can use an f/5 and find it OK for planets then I shouldn't have a problem with an f/8.3 120mm. This option is looking like the best yet for planetary work within my budget.

This may be a dumb question but how does the filter work? I did read about Baader Fringe Killers - do they just screw into the eyepiece barrell like others?
