Hi all,
thinking of buying this cheap GSO ($69) 3x ED barlow from Andrews.com.au to use with 32/25/20/15mm plossls so as to retain the more comfortable eye relief of these EPs. This would give magnifications of 47x, 60x, 75x, 100x, 141x, 180x, 225x, 300x in my 12" f5 Dob which seems like a nice comprehensive range for most targets.
re the 3x ED barlow:
Has anyone used one? Are they any good?
The 2" 2x ED gets good reports - do they apply to the 3x too?
Cheers in advance for any advice.
Doug
