I'm selling my homemade (but NICE) 7" full aperture solar filter. The inner diameter of the cell is actually 8.25"
It's Baader photographic density. For high magnifications (e.g. 200x) it's actually OK for visual as the images are VERY dim in a regular visual density filter. Definitely WAY too bright without an additional neutral filter if you want to look at the whole disk.
Internally lined with felt to protect your OTA, a solar finder is built-in. Comes in a Doskocil hard case (itself a $40 value).
Selling because I sold the Mak.
