image reveals the suitability of the new 10 inch astrograph for
emission nebula. The fast speed, allowed for full size unbinned
color data so to exactly match the Luminance data without comprimise.
Good star images are seen as well in the corners, that Baader
MPCC works very well at this focal ratio. What works for comets
works great for nebula too!|
