Hey Dennis,
I see you are a nut like me. Well I am an amateur nut. I have an ancient astrophysics degree from the early 80's and am about to retire from Air Traffic Control. So, I am learning all of this stuff right now. You mentioned a DSI. I bought the DSI and could not get it to do what I wanted. I was having a hard time getting the image to focus. It updated about every 1/2 second and it was hard to see my laptop screen in direct sunlight or shaded with my old eyes.
I have not used the glass filter yet and do not have a telescope worth putting one on. I invested my first $2000 in the PST, stacker, case, tripod, lense set, barlow, etc... You know the drill.
If you are interested, I have kept a journal of my pathetic images so far. They may have some value as abstract art? Ha Ha.
They are at

ps I am using a Sony CD400 with a home made adaptor (PVC couplings and hose clamps). I am waiting for payday to feed the beast some more.
