This discussion will primarily look at performing H-alpha mod on Sony a7RII. Performing a cooling mod while you have camera open makes logical sense and is becoming a common trend. Details forthcoming...
With the invention of 'Cold finger Inside...', it is becoming desirable to perform astro and cooling modification at the same time. Why open camera two times when you can do it in one?
Note: EOS to NEX adapter shown for using Canon lenses with Sony alpha; telescope use will not require such an adapter!
