Mars Digital Images 2003-07-07

Astro Imaging
Photos 2003 Jeff Treshnell
The upcoming Mars opposition inspired me to attempt digital photography using my Orion 127mm Mak with an Orion variable zoom eyepiece set at 7 mm. I used a 2 megapixel Canon A-40 on the morning of July 7. Hand-holding a camera in front of the eyepiece, I snapped about 50 pictures and chose the best out of the bunch.

It is interesting that the Canon A-40 in fully automatic mode had no problems taking images, but my Olympus C4000Z refuses to take even one decent image. I have fiddled with the manual settings for hours with no success. I received an Orion SteadyPix Universal Camera Mount today, and am eager to try "hands-off" imaging. I will post more photos in the near future.

Good photos - the polar caps are obvious and there are distinct
markings on the surface. Nice job!

I\'d like to make a couple of suggestions, Jeff. Try a few pics with your highest power eypiece that\'s NOT a zoom, preferrably a plossl or orthoscopic if you have one. Fewer lens elements will allow more light to reach the chip.
Also go to http://aberrator.astronomy.net/registax/;aylin.cor@wxs.nl and get a free download of REGISTAX. Several highly successful webcam images have appeared in S&T lately, and Registax seems to be a common program to many of them.
Keep up the good work my friend.

Your pictures looked much better than mine. I think I will try the same thing with my 9mm. Do you know approximately how long the exposutre was? I could not take any pictures beyond a second without the brightness overpowering the picture.

Great Mars pics, Jeff. Keep at it. Maybe a new camera and a laptop would be in order.
