Astronomy Gear Upgrades

I recently picked up a relatively inexpensive larger telescope to help improve my views of the sun.  I say "relatively inexpensive" because a little, cheap camera lens would cost more than this telescope cost.  This new telescope is significantly larger than my previous "large" telescope which should help to see more detail on the surface of the sun...  when and if the skies here ever allow for crisper viewing! Although this telescope is larger, the optical glass in the telescope is not nearly as good as the glass in my other telescopes.  For relatively narrowband viewing of the sun, however, this should not matter.  Since the glass in this telescope isn't "perfect" (to simplify things), it is considered more of a low-end telescope.   When this telescope arrived, I needed to replace the stock focuser.  Most low-end telescopes only come with a single speed focuser, however, it is far easier to focus fine detail when you have a dual speed focuser.
