Ed,

24 mm Konig and 24mm Konig + Ultima barlow. Do I have the wrong
eyepieces for the "double-double"?

peace,
cherokee


The Pronto has a focal length of 480mm, so a 24mm eyepiece gives you 20x
magnification. With the barlow you're running around 40x. I'm guessing
you'll need to get up closer to 100x with that scope to get a good split,
maybe higher. You could try it with the barlow ahead of you diagonal,
that'll get you up around 60x I think. Sooner or later you'll want a
shorter focal length eyepiece for planets and double stars. You might be
able to detect an elogated peanut shape developing when you've almost split
the stars.
