Sky 90 with 2" nose piece adapter) holding 2" Televue Nagler type 4s. Perspective makes Sky 90 look slightly bigger than it really is (see top view below for better size conparison). View as above with dew shields fully retracted. View from above with dew shields fully retracted. As we say here in Texas, "the bidness end" of each. Do i need to tell you which is which?
