Title

127mm Mak-Cass with Homemade Dew/Light Shield

About this image

I constructed this high-tec dew-shield from artist's matt black card (from Hobbycraft) and sellotape. The weather has been so unfriendly that I haven't had a chance to give it a prolonged test, but I am hopeful it will solve the dewing problem on the corrector plate of the Mak-Cass. Anyway, I think it gives the instrument a little more presence!

(I subsequently decided the length was perhaps excessive and cut it back by about half).
