Adapter to place a SolarMax 90 in front of a 6 inch telescope. Aluminum, soft inner lining, six plastic screws hold it on your dew shield. Built for an AP 155. I have no use for it, have used it as a mask for planetary work.
Please see also my ads for a Borg binocular telescope, a Coronado MaxScope, a Starmaster 11 inch Dob, several eyepieces, and an Intes MN61 Mak-Newt.
