This unbelievable webcam picture taken by Emil Kraaikamp shows a pair of galaxies close to Polaris. The spiral galaxy is NGC 2276 and the diffuse elliptical galaxy is NGC 2300. The image is the result of stacking 69 frames of 15 seconds and 66 of 10 seconds of exposure using Philips Vesta Pro 680K webcam as a video camera and a Newtonian telescope Meade Starfinder 10-inch at F/4.5 with equatorial mount.
The Philips Vesta Pro 680K is a modified webcam: long exposure modification, and it has a new black and white chip ccd, the ICX424BL.
