April 27, 2006: How good was the seeing this morning? This is a single pass through post-processing. I *never* get that lucky! A front blew through Dallas this morning about 15 minutes before I shot this 200-second AVI. The temperature dropped about 10 degrees in that time and frost formed on the outside of the scope, then within 5 minutes it had evaporated. Very weird. But it sure helped the air ... This was made with a 6" apochromat, using a Philips ToUCam III webcam, a Televue 2.5X Powermate, and a Scopetronix MaxPower 2 lens (nosepiece barlow), so the focal length is 6,000mm. If you were viewing this live, with an eyepiece, you'd need about 600X to 700X to get this kind of detail.
