Barlow for asi462 and bintel 10" dob
Hey all,
Finally took the plunge and ordered a planetary cam the zwo asi462. Along with it I ordered a baader uv cut filter, zwo ir pass filter and a 5x gso barlow.
Although I think I may have made a mistake with the Barlow and just want some advice before it arrives.
I have a 10 inch f5 bintel/gso dobsonian and the asi462 has a pixel size of 2.9 microns. So with what I've read I should really be looking at a 3x barlow to take me to f15 (5x2.9) is that correct? Otherwise the 5x will be f25.
Would the 5x be useful at all or should I sell it as soon as it arrives?
Kind regards
Greg.
