Took a drive up to High Point Scientific today and came home with a DSI - at the $99 blowout price I couldn't pass it up. Stark Labs has Mac OS X software that will work with the DSI - Nebulosity for imaging, and PHD for guiding - so this should prove interesting. PHD will work with the NexImage as well, I think.
Also picked up a pair of slo-mo extension knobs for the Porta because I'm tired of reaching blindly for the Az adjuster and grabbing the focuser instead.
Had a look at the Celestron C6, I think this is the perfect SCT to supplement my two refractors. I just don't know whether to buy the OTA by itself, or get the SE package and have the NexStar mount as a grab-n-go-to platform to use with the TV85. I was hoping to check out a LightBridge dob but there were none on display.
Incredibly, I managed to leave the store down only $142.00. But I shall return...
