I paid $250 for this lens for use with Astovid 2000 - Collins I3 combo a couple of years ago. I really focused on video through the scope and never got around to imaging meteor showers and northern lights as originally planned though. While I would like to keep this one, priorities have shifted and this is a luxury item I can't justify :-( Absolutely brand new! (note: I didn't notice the fiber particulate from the packaging that shows in the photo or I would have blown it off, but the unit is in pristine new condition all around. Selling for $150 obo. Many thanks for consideration!
