Subject: Monochrome Unibrain results
I recently got a monochrome Unibrain to try and maximize my chances of finding a star to
guide on in my quest to image M51. It is siginificantly more sensitive than my color Unibrain
and being monochrome has a higher resolution.
I was able to double stack a TV 5x Powermate on top of an Orion 2x barlow through my
76mm refractor and still have enough light to image Jupiter. I think at this level the lack of
sharpness is limited by the small aperture optics - roughly equivalent to 450x magnification.
