Hi,
There are heaps of threads relating to your question.
Basically the Meade is not suitable for long exposure photography unless you get a wedge. A field derotator would be limiting and quite expensive. Any alt-az mount will exhibit field rotation (star trails) on all but the shortest exposures.
Since you are looking at SCT's a suitable alternative would be an EQ6 mount, Celestron C9.25, Focal reducer, 3rd party crayford focuser to stop mirror shift, 70 or 80 mm guide scope, Second hand modded 350D camera plus t-ring and 2 inch nosepiece, second hand Meade DSI for guide cam, reticle for drift aligning, guide rings, battery for field use, second hand laptop for imaging.
This setup could be used for visual or astro photography and all up is probably around $5500.
Cheers Paul
