Moon & Mars 1/19/08, 23:16UT

Posted By Dan Petersen
Hi:

The Moon & Mars are in Conjunction this evening - it's a spectacular sight! This photo was taken using my new Sony CyberShot DSC-H7, the settings were; aperture: 17.3mm, F/4.5, s/s: 1/250, ISO: 80, zoom: 15X. The camera was hand held! If you look closely you'll see that Mars is actually red and almost resolved at the 150% setting.

Cheers, Dan grin

Hi again:

Notice how much the Moon has moved away from Mars in just (1h:45m), it's enough to make you dizzy!

Take it easy, Dan 8)

Hi:

What a spectacular site! I took this shot at 5:16 CST (23:16UT) this evening. It clearly shows red Mars only one half degree away from the Moon. I used my Sony CyberShot DSC-H7. The settings were; aperture: 17.3mm, f/4.5, s/s: 1/250, ISO: 80, the camera was hand held.

Cheers, Dan grin

Mars, eclipse night

Posted By Dan Petersen
Hi:

I imaged Mars last night at 1:55 UT, CM = 84. It's only 9.9" now. Meade 10" SCT at F/27 (6850mm). SPC900NC - no filters. 300/3000 in RegiStax 4.

Take it easy, Dan 8)

Saturn - Feb. 24th

Hi, I recorded 45 videos of Mars and Saturn Saturday night in decent seeing conditions, here's a color composite from video #40, it shows the full Seeliger (glowing ring) Effect. More Saturn and Mars postings tomorrow. Cheers, Dan smile

Mars ( Feb. 24th) fl = 14,000mm

Hi again:

Mars is now very tiny (9.6") so I powered up my 10" scope to F/55... here's the result. More images tomorrow.

Take it easy, Dan 8)

best Saturn... so far

Posted By Dan Petersen
Hi, I really tried to nail the colors on this one, using the South Olivette Cap as my color key knowing that it truly is olive colored. I also tried to make the globe as bright as possible without any blooming, then I reprocessed the 2,144 frame stack to bring out very fine cloud details and at the same time attempted to keep the whole thing as smooth as possible. Cheers, Dan smile

PS: Next time out I plan on capturing a few Saturnian moons (like the good imagers do here), that adds a lot to a planetary composite like Steve's excellent posting.
