This shot of mars was taken using my 6 inch f8 (ATM) Dobsonian and Sony TRV17E digital handicam, eye peice projection through 9 mm plossle and 2 x Barlow. I just hand held the camera at the eyepiece and by tilting the camera I can get about 250 frames as the planet moves across the field of view.
Camera settings were:
AE = sunset/moon
auto shutter off
optical zoom about 7x
exposure about 70 %
best 176 frames out of 296, processed in Registax supersampled 1.5x, further processing in Gimp using Panorama tools 'correct' add-in to remove blue/red fringeing and slight unsharp mask to improve the final image.
Sequence taken 2003/7/29 12:41 (UT) CM 62.81 dia 21.88 arcsec , Mars was at Alt 42.5 degrees at my location.
I am new to this so any feedback on the image much appreciated. Also interested to hear of any others success with this technique particularly with regard to camera settings.
Many thanks
