Baader Blue 60mm CaK ERF

For sale is my Baader Blue (B-CCD) ERF for CaK and CaH. It was used with my Skywatcher ED80 (80mm f7,5) refractor for CaK imaging. It is a 65mm x 65mm Baader Blue (B-CCD) filter housed in a homemade acrylic cell to give 60mm clear aperture. Filter is 289 euro new alone.

https://www.baader-planetarium.com/en/b ... blue).html

The ERF cell was designed to fit in the end of the dewshield of the ED80 like a push fit bottle stopper, inside diameter approx 111-112mm, outside flange approx 121-122mm, can be easily removed / disassembled if needed. Would work well in the way I used it - makes the ED80 a 60mm f10 scope which is ideal for CaK filters, or, could be mounted internally as a CaK/CaH ERF. Or, you could just use the filter in it's own right... Is in excellent condition.

£150 p&p included within UK, postage at buyers cost outside UK. Payment via paypal 'friends and family' or buyer pays fees.
