Different FOV with two 4.8 Naglers

Posted By Kevin Morgan

Anyone know of a reason that two different 4.8mm Naglers should have different fields of view? Last night I was out observing with my friend. We were comparing the eyepieces and noticed that my friend's older e.p. had a wider field than mine.

What kind of diffraction pattern can one expect to see with a curved vane?

Spider recommendations for big Dobs.

I use Astrosystems spiders and secondary holders and I love them. I especially like the 4 extended collimation adjustment screws on the secondary.
