Mars f45, 12/7/07

Posted By Dan Petersen
Hi Steve, very impressive! I can actually see the NPC in between the flanking NPH clouds. That same airmass was over my location the night before, CSC was predicting 8/10 seeing, it turned out to be 1.5-2/10. sad So once again that's a great shot considering the airmass you had to deal with! I can't wait to see your Mars composite when really good seeing parks itself overhead. Cheers, Dan 8)

PS: It looks like you found a great method for collimating- I'll have to give it a try.

Mars Dec 5, 2007

Hi Paul, great detail. I see the NPC is slowly making its grand appearance, just in time for opposition. This makes your 78th Mars posting over at the International Marswatch site, that's amazing. The image quality has really progressed since you started back in May. Good luck with the tri-colour imaging. Cheers, Dan

Another Mars December 10, 2007

Posted By Dan Petersen
Greetings John, WOW, that's a stunning composite it shows considerable surface detail and atmospheric activity, very impressive. Thanks for giving me permission to try tweaking it. First I saved it as a bitmap then transfered it to Microsoft Digital Image, there I slightly increased the saturation and adjusted the red, green and blue colors, I increased the contrast and rebalanced brightness,(twice actually) this also helped to sharpen the Martian limb. Finally I saved it as a PNG in order to increase resolution. I hope it's an improvement. Cheers, Dan smile

Hi Steve, that's a beautiful Mars! All you need now is just one night of perfect seeing. It's clear here so I'm on my way out, seeing is decent. Thanks for posting, Dan

Moon & Mars shot from Florida Dec. 23

Posted By Dan Petersen
Greetings Jason:

WOW, that's a spectacular capture, you should send it off to Spaceweather.com, I'm sure they would post it immediately since they're talking about this conjunction. It's not easy to get a $1,000 photo from a $100 scope, congratulations. I think I can even see the "NPC" on the right side of your Mars image, that would be its north pole. You sure are lucky to be living in warm and sunny Florida, that's an ideal location for planetary imaging and golfing, take it easy.

Cheers, Dan grin

Mars images from Opposition night!

Posted By Dan Petersen
Hi, Here's a brighter and larger desktop version. The individual images of Mars form the letter "M" and the entire montage is shaped to resemble a lunar lander, which you may have already noticed. I'm planning to assemble an animated .gif showing 19 degrees of global rotation that's about 80 minutes, it should be quite interesting. cheers,Dan smile
