I have a Celestron Xcell LX 5mm that I use for planetary, and it is quite a good piece of glass. It is said here and there that it is closer to 4.6mm than 5mm, but the wide fov and comfortable ER are very nice.
When seeing conditions are great I use a 2x barlow (Celestron Omni) and I was wondering if this configuration brings the same visual results than using the 2.3mm Xcell LX, or if it was worth ordering the latter to give it a shot.
Since the 2.3mm and the 5mm are built with the same amount of glass, and since there is one more piece of glass with the barlow, is it fair to assume that at this very high magnification the 5mm + barlow would produce more blur than the sole 2.3mm EP?
