Well, we had a good run of clear night skies last week, and here we are heading toward the new moon, and it's going to rain for three or four days. Anyway, it was great while it lasted. Taking very long exposure images with a telescope, and by long exposure I'm talking the shutter open 5 minutes for each frame. 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.
