Mars f25, 9/18/07

Posted By Dan Petersen
Hi Steve:

Great composite, I love it. The light levels, contrast and color are all exceptional, congratulations. It looks like you had about 6/10 seeing.
One of these mornings I'm going to try imaging Mars with both eyepiece and negative projection to see which one gives the best resolution.
Steve, keep working on that cooling situation, it sounds like a small fan located by the baffle tube may help with the cool down. smile

Cheers, Dan

Congratulations, (Alan and Donna) on your 26th wedding anniversary and what a spectacular gift, how many husbands can present their wives with the bright and morning star? What a great capture, you're a lucky man Alan. Man's future is in heaven (in more ways than one), and it's only natural that we should be interested in its every aspect. Cheers, Dan

P.S. I see spaceweather.com is "featuring" your Venus image, well done!

Hi Dan -

Very nice work on this and also your new Venus image!

best,
Alan

Hi Al, thank you for taking the time to view my first real attempt at Mars.
This should be an awesome apparition of the red planet with a declination of
plus 23 degrees now and with a surface area that will increase nearly 4X in the
coming months - what more could we ask for. Thanks again, Dan 8)

Dan, excellent Mars image! Details and color are crisp especially the polar cap.
You really have that scope setup well. Thanks for posting

Regards,
Steve

Hi Steve, when I walked into my observatory this morning I noticed the air inside
was noticeably warmer than the outside air temperature. There are two types of mirrors
under corrected and over corrected, to one degree or another that is. My scope must
contain the former because it performs well in cooling and cold temps. I'm anxiously
awaiting the first blast of Canadian air. I appreciated your comments very much, Dan smile

Great shot Dan!
What scope/settings were used for this shot?

Looking forward to more shots from you, and to Florida's Winter time... 8) (tired of waiting for good weather... hot-muggy-rainy+mosquitoes)


Clear skies!

Hi Ivan, thank you for viewing my Mars shot. This is my rookie year for imaging solar system objects.
I have a lot to learn but that's half the fun, it's all new and exciting.

I used my 10" scope, it's the same as yours - minus the bells and whistles! No filters were used.

As for the spc900nc settings, here goes; speed = 10fps, exp. = 1/10th sec.(0/10)
gain = 2/10, brightness = 4.7/10, gamma = 5/10, saturation = 7/10 and the focal length = f/20.

Processed in Rv4, best 300/1300

Thanks again, Dan grin

Hi Dan,

Excellent Mars image one of the first I have seen this opposition with such a prominent NPH.


Thanks,

Wes Higgins

Hi Wes:

This sure is a fun hobby, relaxing too. Thanks for your comment. By the way check out the solar system forum at cloudynights.com and this mornings image of Mars
(by Pete Lawrence) it's amazing.

Cheers, Dan 8)

Mars this moening

Hi Jim:

Excellent image, tons of detail. Just imagine three months from now how incredible Mars will look! I can't wait...

Cheers, Dan smile

Hi Paul:

That's one beautiful shot, loaded with detail and very colorful. I'll bet SunShine likes it too. wink

Thanks for posting, Dan

Venus September 25, 2007

Hi all,

A while after shooting the above Mars images I took a try at Venus. I think I may have captured detail in UV, and the W.L. image looks pretty decent I think.

Paul, it looks pretty good to me also. Venus is a rather tricky target, I have yet to see a perfect shot of her... maybe someday?
Attached is my latest effort at this dazzling gem. I see the morning sky is starting to get crowded, now that Saturn is making a ringside appearance.
Thanks for the posting, Dan 8)

Phases of Venus

Posted By Dan Petersen
Hi Curt:

Venus just happens to be my imaging specialty. I've attached my color montage that clearly shows her phase change this year. The dateline runs from
(March, 29th... August, 12th). I hope you enjoy it. I have several other CCD composite images posted in the solar system forum, you may find those interesting also.

Cheers, Dan 8)
