.......Taken on November 04, 2007, 22:37 UT. Gordan, You and David C got comet images about the same time and both show the bright nucleus. However, a few days later I was unable to see it in my 20x80 binoculars. Perhaps it was my sky conditions? George N |

Holmes - single 25 sec exposure
George,
yes, it could be your sky conditions. It seems to me that I have very favorable conditions here in northern Croatia, the air seems to be very clear (when it doesn't rain like now :-). Maybe the same is with David but his exposures are generally about ten minutes (L,R,G,B together) and that one of Nov 05 was total 72 minutes. I am always surprised how easily I get the nucleus and a lot of stars in such a short exposure time (remember that I got this image in only 25 secs!). It must be the good transparency. Thanks God! It looks promising since I started with digital imaging only few months ago. Many greetings, Gordan "George Normandin" wrote in message ... "Gordan" wrote .......Taken on November 04, 2007, 22:37 UT.
