Solar Images Below are selected solar images I've acquired with a cannibalized inexpensive webcam (the guts of a Philips Vesta 675), cooled with two small CPU fans. The camera is attached to an inexpensive 150 mm f/8.0 achromatic refractor (one of the recent Chinese imports). The CCD in the Vesta series of webcams is a 659×494 5.6 micron square-pixel Sony color CCD. The onboard electronics resamples to produce 640×480 8-bit RGB output.
