The lens gives a hazy image, and focus is a little soft. Image is so poor that even in monochrome that is solar H.alpha in my Quark, the image is both hazy and soft. Not a piece of glass I will be passing on to anyone, only the bin.
I did have an 80mm f/5 scope that used a lens from Surplus Shed. Now that WAS a good lens for a modest achromat. Had a 2" focuser too. I sold that little scope long before I got the Quark. Would have been a match made in heaven... Now I'm looking for another...
