Well, we had a good run of clear night skies last week, and then it rained for three or four days. I set everything back up this afternoon, going with the full RGB + Ha filter set tonight. It’s all about taking very long exposure images with a telescope, and by long exposure I’m talking the shutter open 5 minutes for each frame, taking a hundred of these through the night while holding the sensor temperature to nice cool -10C the whole time. Every image I captured over the last five clear nights has been through this 8 inch Newtonian scope (8 inch primary mirror (203mm) inside the tube where the gold foil cap covers the end, the secondary mirror is where the camera connects to the focuser, toward the top of the scope). And I ran every night’s imaging session with the ZWO ASIAir controller.
