I'm interested to know whats the best filter for eliminating light pollution money can buy. With the dry session here the red levels are is just through the roof on the RGB level chart. As for the the heat of 550d sensor, im just going have to get a astro CCD in the near future.
All in all it was just great throw the telescope back up, and blow off the cobwebs!!

Hi Dan
In regards to the high sensor temp do you pause between shots? I find this helps to cool the sensor by pausing for 1 minute per shot.
