A Philips SPC900 camera fitted with a Moon filter, was placed at the prime focus of an f/10, 6" SCT. Overlapping AVIs were captured and processed in Registax. Microsoft ICE was used to stitch the images together into a mosaic. Click on the image to get a larger view:

Supersaturated 96% waning, gibbous Moon

A tripod mounted Pentax K-x DSLR, fitted with a 300mm lens was set to ISO 200 and 1/320s exposure. 16 images of the 96%, waning, gibbous Moon were captured in quick succession in RAW format. The RAW files were auto white balanced and converted to TIFF format. The 16 TIFF files were then stacked in Registax 5 to produce the final image. The image was then colour supersaturated to reveal differences in the colour of the Moon's surface, reflecting the composition. A blink comparison animation was then made to show the difference in appearance of the Moon when the image is supersaturated compared with no enhanced saturation.

To See The Beginning Of Time

This evening, Andrew Lound gave a dramatic lecture entitled "To See the Beginning of Time". The lecture was well attended and greatly appreciated by the audience:



The lecture was followed by lively discussion. 
Andrew will be giving the Swansea Astronomical Society Christmas Lecture at the Swansea Waterfront Museum on December 7th 2013.

Full Moon

A tripod mounted Pentax K-x DSLR was fitted with a 300mm lens. The ISO was set to 200 and the shutter speed to 1/320. A remote control was used and 16 images of the Full Moon were captured in RAW format, in rapid succession. The RAW images were then white balanced and converted to 16 bit Tiff files. The Tiff files were stacked in Registax 6 to produce the final image, which was saturation enhanced to reveal the surface composition:

97% full waxing Moon

A handheld Pentax K-x DSLR fitted with a 300mm lens was set to ISO 400 and 1/800th s exposure to capture this image of the Moon. The saturation was increased to reveal the subtle colours on the Moon's surface that reflect the mineral composition. Click on the image to get a larger view:
