Well, I agree with everything that @tekn0lust has said. Astrophotography is a complicated endeavor. You need a guiding scope, an autoguider, software (usually in a laptop), imaging software, etc. The EQ1 mount may be sufficient for visual astronomy, but I don’t know about astrophotography. I have a Tec 140 with an EQ6 mount, and I’m worried about the EQ6 mount and its astrophotographic capabilities. Have you decided on your CCD imager yet? Are you going to go with DSLR? Are you going to modify the filter on your DSLR? Here is a Cloudy Nights review of the scope you’re looking at: http://www.cloudynights.com/item.php?item_id=745
You mention that your scope produces great photos. The photos are less of a function of the scope (although granted that is important) and more of a function of the mount and the guiding software. Don’t expect to buy a scope with an inexpensive mount, hook up a camera, and snap away. Sadly, it’s not that easy. I know people who have spent thousands of dollars on imaging equipment (and in one case tens of thousands of dollars). Lastly, imaging planets and imaging deep sky objects take two entirely different techniques—and often different equipment.
Be very careful lest you be disappointed. I know a guy who spent thousands of dollars and hundreds of hours before he realized he bought the wrong equpment and had to start over again.
