After way too many days of cloudy nights/mornings and poor seeing, the new year brought a welcomed gift of a clear sky and calm winds. Seeing was OK – good enough for f/10 and a red filter on my C-11. I shot video of Venus, Mercury, and 44 views of the Moon. The latter I processed and combined into a mosaic. Click on the thumbnail to view the full resolution version. It is 8MB – be patient and don’t give your network a hernia.
This was done partly to relieve the frustration with the weather and also to test out a new version of AviStack (v1.74) before it is released for general use. This new version has several new features, one of which is a Wavelet enhancement tool. This mosaic is comprised of 34 frames, each of which were derived from the best 100 frames out of 1300. They were enhanced with the new wavelet tool using three layers (0.20 @ 120, 0.32 @5, and 0.45 @ -2).
I used my Celestron 11 at f/10 on my AP 900GTO mount with a red filter and a TIS DMK31AF03.AS firewire webcam. The gain was set to 350 and the expsosures were 1/38 second. AVIs were captured at 30 fps using the Y800 codec. Each 1300-frame AVI was captured in just over 45 seconds. I captured all of the data in about 30 minutes, but it took me two and a half days to process it and build the mosaic. I guess I need a faster computer.
