--MichaelDark site scope: Meade 8" f/6 DobWeeknight scopes: C9.25/iEQ45M, C102/LXD-75(I am looking for a 1980s Edmund Scientific 3" f/10 red-tube reflector, PM me if you have or know of one!)
Quote:Hi all,Been trying to figure this out, but can't seem to find the right answer. What influences seeing the secondary mirror when looking through an eyepiece on a Newtonian? Is it too large of an exit pupil?
Quote:I am a self-avowed disbeliever of the eyepiece exit pupil dogma, but even so I have never seen the secondary shadow while observing at night. Add it to the long list of things that don't warrant worrying about.
Quote:Thanks Don (and all)! That explains it clearly. Also explains how I notice it in my 32 mm Plossl on my 8" when viewing solar. I just have to pull back from the eyepiece ever-so-slightly and I can see it.
