While you're here, how about checking out the
Astronomy Book
List ? |
My 31mm Nagler 5 easily gets the most use. It does show color on bright
objects like Jupiter, Saturn, and the moon, but not on the faint stuff. The
Nagler AFOV is awesome, as you'd expect.
I've heard that they are extremely difficult to get right now, something
about one of the more exotic elements not being available. This may
influence your decision more than anything else!
