Those are realy nice pictures. Nice gear head you have too, here's
what I was shooting with
If you have a 1000mm scope then it's realy no big improvement, but it
looks like rubinar has much larger aperture so it should have more
resolution. How wide is the objective of your scope?
Planets are realy much too small to make impressive photos with any
camera lens. I was thinking more of making photos of nebulae galxies
etc. that fill the whole frame. For that I'll use much shorter lenses
too plus all else.
