Moving on From The Meade LPI
Posted 23 February 2013 - 12:31 PM
a) Will mostly be used for Lunar and planetary images
Will probably not upgrade with a wedge and/or polar alignment
c) Would like to try some Deep sky imaging
d) Don't want to spend over $400-$500
e) I have really dark skies
I figured some of the experts in here could help a brother out. Any and all feedback is appreciated.

If planets are the primary interest I'd get the one shot color, long exposure dso go mono and invest in a filter wheel later. Long exposures however can be problematic without a polar mount.

That would be my next step up. For a little more, you could maybe find a used Orion Starshoot Mono III or a DSI III around ~650.
A regular DSI can be had between 1-200 bucks and a DSI II just a tad more than that. If you get two of them, you could be guiding too!

Lol, to be honest the DSIs are a cheap way to go if money is the main concern (and you can find one for sale) but the lack of cooling makes them not my first choice nowadays. I'm pretty sure they can't match the Titan's 15 fps framerate either.
I'm surprised Mike didn't offer up a DSI .
I stuck with the DSIs because I also have 2 Outback cooler units. Getting consistant darks without some form of temp regulation is quite the chore, especially the models without a temp sensor, and usually ends up with dark capture interspersed with the imaging run for best results.

Another option would be to get a widefield scope of some type and piggyback her on your LX90. It'd be a bit more friendly to the smaller chips you're looking at getting, and you can re-purpose it as a guidescope.
Don't you hate AP? The cost just keeps going up!
And John has a good point, you could get a T2i or similar Canon DSLR for the cost you listed. It would actually work better (due to image scale) than the small chip CCDs we've been suggesting too.

I garnered most of my basic image processing knowledge from Ron Wodawski's book, "The New CCD Astronomy" which, I believe, is now available as an electronic book. There's very little in the book that doesn't apply to DSLR imaging as well as CCD astro cameras.
