I am attempting to run my Solar Spectrum ASO 0.5 ang. etalon on the back of my CR-150 telescope.
This year has been ‘dier’ (spelling) with my 200mm HaT- no images, last year some 30+ images at all resolutions. Anyway, I want to run this combo to take advantage of small refractor imaging.
I think that I am in touching distance of having it come to focus.
I have found two components that make this happen a M42 / T2 short 15mm tube screwed into the SS and a 2” short tube from a Twist-Lock Adapter by Baader. This is the shortest I can go! Baader must do a direct ‘short’ connector but I haven’t found it. Any ideas to help me out.
Oh, I have written to both SS and Baader for some ideas but they are under a lockdown!
