Terminator: Copernicus to Pitatus

Posted By Dan Petersen
Hi Stefan, what can I say other than - WOW! Your 130% enlargement is an absolute feast for the eyes, it sure is a magnificent close up! Ones imagination can work overtime trying to figure out how all of this topography was created. Your lunar composite started me thinking that perhaps many of the Moon's tiny craterlets are from reentry debris caused by asteroid impacts, like the one that created Copernicus. The Moon is a very interesting place, I hope we'll have the opportunity to travel there within the next 25 years. Thanks again for all of your hard work in capturing and processing this one. Regards, Dan grin

Posidonius and Le Monnier

Posted By Dan Petersen
Hi Mike:

Outstanding resolution and excellent processing, congratulations! Posidonius must be one of the most fascinating rimmed craters on the moon. I can just picture a bunch of us walking around inside it and being in awe of the views. Hey, it doesn't cost anything to travel, when using your imagination. Thanks for posting this great shot, and your earlier lunar posting as well.

Cheers, Dan smile

Saturn Halloween Morning

Posted By Dan Petersen
Remarkable image, Jim! It's sharp with great color, and is very strange looking, almost spooky. 8O I think your Saturn composite is the finest one to be posted this preseason, congratulations. Regards, Dan

Hi Paul, really impressive, well done! Dan grin

Saturn Nov 24

Posted By Dan Petersen
Very good, Jim! I can detect at least 14 bands, even the SEBz. Now if we could order some 8 or 9/10 seeing conditions we might come close to Chris Go's latest Saturn posting on his website... http://astro.christone.net/saturn/index.htm cheers, Dan grin

Saturn ( Nov 27th, 11:33 UT)

Posted By Dan Petersen
Hi:

Here's a 1440 frame reprocess and resize. As you can see I need to very slightly adjust my 10" scopes collimation on the horizontal (east-west) axis.
Saturn's current ring tilt is minus 1.2 degrees and shrinking. 8O E. Dia. = 17.3", Ring Dia. = 39.4"

Take it easy, Dan grin

Saturn & Titan!

Posted By Dan Petersen
Hi, here's a 950 frame stack from video #1 (imaged at F/28), it's much smoother than the 360 frame preliminary composite captured at F/38. You can see several bands including a portion of the SEBz.

A chilly Thanksgiving morning

Posted By Dan Petersen
Excellent, Jim! I like the rich colors. I was up at 3:30 today, veiwed the winter Constellations for a while, even saw a Leonid meteor. It was 20 degrees here this morning and that's warm compared to what's coming in the next few months. It sure would be nice to live down in Key West, 70's every night with great seeing! Regards, Dan smile

Saturn This Morning

Posted By Dan Petersen
Grand indeed! That's the best one of the season, it was worth freezing for. I see we can image it on or near the meridian now for the first time. Take it easy, Dan 8)
