Quote:Had this out last night again looking at Jupiter and was getting some really awful "ghost" images. Or at least that's what I think people are talking about when they say ghost images. What I was experiencing was a dim "star" that moved around as my eye moved, and also a very reflection looking thing that moved around as well and was very distracting/annoying.
The only thing different between the first outing and this outing is I cleaned a small smudge off the lens using a touch of Isopropyl alcohol, but the lens looked very clean when I took it out so not sure that was the effect. I didn't have my other eyepieces with me so I couldn't properly determine if it was in fact this eyepiece or something going on with another component.
Has anyone had this issue with this eyepiece, and if so is there a way to minimize/eliminate it?

Quote:Mike Hosea explained the ghosting thing on here. If the image moves around it is from an external light source, or from your eye and not at fault with the eyepiece IIRC. I don't think dark adaptation has anything to do with it.
