That does not appear to be a response or critique of the video to which you were directed.

i didnt watch it yet.i was minding my granddaughter. .but again there are pros an cons to it.do you yourself believe in global warming? when i get the chance, tommorow ill respond.thx centaur
Yes, Robert, anthropogenic global warning is not in scientific dispute. Some corporations find it in their interest to disseminate confusion to their media allies, just as Professor Wuebbles implies in his video. All that really should be in debate is the degree to which it might be harmful.
I shall await and respect your critique of the video. Keep in mind that Professor Wuebbles may not sound as silver-tongued as TV commentators like me, but he knows his science.

john,nice avatar ,i didnt notice it till rick gave me heads up.very nice.i guess you used eyepiece projection at sundown?
That particular sequence is made up of images taken from Oct 15 to Nov 2 of 2008. It covers Mercury through it's western elongation, and each frame is processed from videos recorded roughly around mid-morning. Most of the surface features shown are of the so-called non-Mariner side of Mercury. At the time of that sequence, the Messenger spacecraft had made 2 flybys of Mercury which recorded some of these features in detail for the first time. I had done a similar sequence in 2007 before Messenger imaged the planet, but improvements in technique resulted in better detail and contrast in the 2008 version.
I image Mercury using Barlow projection and usually near-IR longpass filters. Perhaps my best image to date is this one presented on the ALPO website: http://www.alpo-astr...rcuryblog/?p=52
Be sure to click on the image to enlarge it.
That Messenger comparison presentation was put together by ALPO Mercury coordinator Frank Melillo. Obviously there is no real comparison to the incredible Messenger image, but at least it demonstrates the reliability of the features I recorded that day.
