DayStar 0.8 A wide, 6562.8 A H-alpha Solar Filter, model ATM, Serial
Number A-1283, which I purchased in 1983 for US$1300. These have
finite lifetime with possibly expensive repair and this one failed in
the mid 1990's. The cementing came apart partially and I dissassembled
the rest of the unit to take a look. Selling all parts shown in
picture, oven, etc, including the required 1.5" aperture Red filter,
which cost US$240, for mount on a 3.1" f/15 refractor (refractor not
included), and the original documentation. Original wooden box not
included. Heater runs on US 120 VAC. Will sell for US$225.00 which
includes Australia Post Air Mail shipment to the US or Australia.
US Dollar drawn US Postal Money Order, Bank Check, or cash only.
