Mars in late October 2005. I shot this image of Mars during the 2005 close approach. It is a stack of 1200 frames averaged together to eliminate noise and enhance trey detail. I used a Celestron C8 scope and a Sony camcorder. I mounted the camcorder to the telescope eyepiece with an adapter, then used the Sony’s optical zoom to enlarge the projected eyepiece image. Shooting video at 30 frames per second quickly gathers a lot of frames. About 1 minute of footage was split into individual frames in stacking software. I used a comparative sorting algorithm to cull out the blurriest frames, then aligned and stacked the remaining 1200. The resultant image was processed by optimizing histogram values to preserve the captured color, using Laplacian pyramid sharpening, wavelet noise reduction, then final Photoshop processing.
