Binoviewing's Dark Secret?Posted By Milton Wilcox |
The sweet spot for my setup is between 60x and 120x. Although the OCS does a nice job eliminating coma, below 60x (I can go all the way down to 38x/1.63° with 24Pan's), edge stars begin to defocus significantly due to Newtonian field curvature. Above 120x, spherical aberration limits the sharpness. Note, at high powers I am effectively running at f/7 due to the approx. 1.8x I get with the hollow nosepiece.
Don't forget to add "expansive effect" to "comfort" and "floater reduction" for the benefits of using both eyes. I really am a dedicated two-eyed observer as Brian knows from the binocular forum. I just happen to think there is still room for significant improvement in binoviewers. Nils, I look forward to your thoughts.
