The APO barlow arrived so back outside for another test. The cheapo no name eBay barlow is just as good. My target was two small twin craters. One crater had a structure inside of it. I tested the two over and over again against that structure. However, I could not find a noticeable difference in sharpness. It written on the side of the eBay barlow FMC.
I also tested the Svbony zoom against the GSO Superview 20mm and the Agena Starguider/Astro-Tech Paradigm 15mm. Testing at the same magnification the Paradigm was equal to the Svbony zoom. The Superview was slightly not as sharp.
Once again thanks for all the help I have gotten.
