You won't see this very often, a B&L 4000 full aperture solar filter. It screws right into the end of the OTA negating any possibility of it falling off. The glass and coating is in outstanding condition with no apparent spots or scratches. There is some wear to the outside black finish, the worst of it shown in the last photo. I had thought to keep for this for the 2017 eclipse, at the very least able to hold it up for safe viewing, but I have other means to do that. No 4000 is complete without one. $60 shipped CONUS payment by PayPal, I pay the fees.
- Condition Glass- excellent, metal finish as noted.
- Location Atlanta
