3D (Jupiter, Io) transit

Posted By Dan Petersen
Hi all:

Had a great time imaging this beautiful transit last evening. At an elevation of only 19 to 20 degrees it's hard to record much detail. The right image is a composite of 1575 frames taken at 3:12UT and the left image is 300 frames taken just 6 minutes later. Meade 10" SCT at f/28 (Ultima 2X), SPC900NC, Baader UV/IR cut, Rv4, Seeing: 4/10.

Take it easy, Dan grin

PS: If your eyes stay crossed, don't blame me... 8O

Jupiter 8/1/08

Posted By Dan Petersen
Hi, here are a few Europa Shadow Transit shots that I took Thursday evening in 5/10 conditions with Jupiter at an altitude of about 21 to 22 degrees. All of the composites are aligned for 3D viewing. With some good seeing I think it will be possible to capture a very detailed image this season, time will tell. Thanks for looking, Dan smile

Saturn 11-23-08

Posted By Dan Petersen
Hi all:

I managed to capture the "Spiked Planet" this morning, it sure is a strange sight in the eyepeice. Seeing was good but not steady due to an upper level cloud deck. This is my first Saturn post of the season, they can only get better from here on out. Setup, Meade 10" SCT at F/35, SPC900NC, processed (1435/3300) in Rv4.

Cheers, Dan grin

Saturn & Titan!

Posted By Dan Petersen
Hi all:

Well, here's an interesting and quick (preliminary) composite from this morning, seeing was as good as 7/10 at times. In my opinion this is the grandest planet of them all, orange Titan was also close by and in the neighborhood! I have several videos to process. I tweaked my 10" scopes collimation before imaging, the optical alignment has improved considerably now. I imaged at F/38. "De" is only 1.2 degrees!

Thanks for looking, Dan smile

Saturn with Titan in orbit!

Posted By Dan Petersen
Hi guys:

Here's my final process. I'm waiting for the next clear night now, should be able to post better ones in the months ahead, if my equipment and I don't freeze solid.
November 29, 2008 (12:18UT), 10" SCT, Fl = 9,600mm.

Cheers, Dan smile

Amazing movie!

Posted By Dan Petersen
Hi all:

Here is an awesome six day movie of our sun as it slowly pulls away from Mars (the bright star to its right), and then approaches the Sagittarious star fields. Also notice the hundreds of meteors, and last but not least the powerful CME exploding off of the Sun's eastern limb! http://sohowww.nascom.nasa.gov/data/LATEST/current_c3.mpg
This movie is 7.2 MB, it may take a couple of minutes to download. Hope you enjoy it, Dan grin

The Straight Wall

Posted By Dan Petersen
Hi: Did some lunar imaging yesterday evening, anytime I can make the Straight Wall look crooked, I'm happy. The tallest points on this 75 mile long fault are approximately 1/4 mile higher than its eastern floor (Mare Numbium). Christiaan Huygens called this feature "The Sword", with the ridges at the top of this photo being the handle of the sword, and the Straight Wall itself is the blade. Meade 10" SCT, 525 stack. cheers, Dan wink

Saturn 1-18-09

Posted By Dan Petersen
Hi:

Here is a 2,050 frame composite of Saturn, taken from the Chiefland, Florida 'Astronomy Village', at 10:05 UT this morning. The Ringed Planet was up 62.75 degrees, and seeing was about 7.5/10. I imaged using my 10" SCT at F/41.0, an SPC900NC webcam was used with no filters. The ring tilt is (-1.1) degrees, Saturn's diameter is 18.91". CM1= 306.5, CM2= 356.8, CM3= 264.9.

Hope you like it, cheers... Dan 8)
