Im looking for a mid range plossl 10-12.5mm in Vgood condition for my 5" newt.
I currently have both 20mm and 6.5mm silver sided plossls, and a 10mm in this range would complete a set for my travel scope. Failing that, a 10 or 12.5mm of another reasonable type will do. ( No Andrews plossls please !)
I have a 10mm skywatcher plossl, with single layer coatings. Plastic all the way! (...except the lenses) I don't think it's what you're after but it could work until you get something better.
