When I started out in astronomy 25 years ago, i had bought a Celestron Ultima SV series barlow. I was looking it up just now and estimating it might have cost $50-60? new.
It's outdated for one thing, but was looking at a few nice barlows on Amazon that are not too much more than that. Should I update?
Do you think it would be worth buying another one? I'm hoping it would make an improvement in image quality since I recently bought a few expensive eye pieces.
By the way would a 2x barlow have any adverse effect on 5.5.mm and 14mm Meade 82 degree eye piece since they are such a curvature on them?
