I am looking for a Barlow lens for my 76/700mm reflector to use for lunar and planetary imaging. Now, I know that this probably isn’t the best scope for the purpose but it’s a present from my wife and has some sentimental value. So please bear with me |
I have a cheap 2x lens that came with the scope but it’s rubbish. I realize that a 3“ mirror has limitations in resolution so I am wondering which is the most reasonable Barlow to buy: 1.5x, 2x or 3x magnification? Without Barlow I am 1 arcsec/px scale on my camera.
Thanks a lot for any tips!
