Which 3x Barlow for Planet Imaging?
Hi All,
Would like some recommendations on which 3x Barlow to get for Planet imaging with a SCT? I have a C8 but will be looking to move up to a C9.25 or C11 some time down the track. Would the 40-50$ ones be ok for Imagin purposes.
Would a 2.5x Powermate be better? From what I have read the powermate was designed to overcome the impact of barlows on a longer FL EP's. So would it make much difference to small CCD sensors used for Planet imaging?
Regards
Fahim
