To black or not to black, that is the question
Had a mate turn a solid aluminium adaptor for me so that I can mount my autoguider with 1.25" nosepice onto my old Meade (Tasco) 60mm refractor (that has 0.965 drawtube etc). All I needed was some 1" aluminium tube so I could achieve focus.
Anyway, for guiding, is it beneficial to blacken the inside of the drawtube etc to minimise reflections, or not matter so much?
