Left: The Moon.  Click the moon image to see a crisp view of the full moon.  The image was captured prime focus in an Orion 80ED refractor telescope with a Canon 350D at ASA100 with a shutter speed of 1/1000th second.  This is the result of stacking 77 exposures and applying wavelets in Registax to bring out the crisp crater detail.    Click here for the large version.
Gassendi Crater Left: Gassendi Crater.  Taken with the new GSO Ritchey-Chretien telescope and a x5 Powermate barlow with the DMK video camera.

The Moon: The Sea of Tranquility

Left: The Sea of Tranquility.  If you click the image at left you'll get a closeup view and the location of the Apollo 11 landing site is shown in context.  It's an interesting factoid to know where they landed.


Below: the stark but beautiful craters and mountains of the moon as seen through a Mintron video camera.  Click the images for closeups.

These images (except the top one that was captured by a Canon 350D) were captured with a Mintron 13V1C video camera at prime focus of the 8" Schmidt Newtonian.  The video (.AVI) frames were stacked using Registax software to average out the effect of atmospheric turbulence and to sharpen up the edge detail.

To get a high magnification onto the video camera's chip (i.e. so the image covers as much of the CCD chip as possible [called image-scale]) a Powermate (x4) or Barlow (x2) is used to increase the focal length of the telescope,  For high magnification (zoom) images the x4 Powermate and the x2 Barlow were used at the same time.  The maximum amount of useful magnification is dependent very much upon the seeing conditions.

Focal length of the SN-8 is 812 mm  (f-ratio f/4)

Focal length of the SN-8 with x2 Shorty-Plus Barlow is = 1624 mm  (f/8)

Focal length of the SN-8 with x4 Powermate is  = 3248 mm   (f-ratio f/16).

Focal length with x4 and x2 together (x8) = 6496    (f-ratio f/32)
