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.
