ASTRO: Comet Holmes at 4:00 UT on Nov 2, 2007
This is taken with an STL-1301E thru an OGS 20-inch RC Cass working at
around F/5. The field is still two small to see the outer envelope in this image. This was a 5:2:2:4 minute LRGB exposure, made while chasing the comet thru clouds. George N |

VERY nice image, George!
I like the sharpness of your stars... :-) Mine are not so sharp (yet :-) Gordan "George Normandin" wrote in message ...

George, isn't your image mirrored (mirror-flipped)? I compared it to mine
and found that they are mirror-symetrical. Greeting, Gordan "George Normandin" wrote in message ... This is taken with an STL-1301E thru an OGS 20-inch RC Cass working at around F/5.

Nice George - got Holmes in the binos tonight (b/w cloud banks shed by
Noel) and the scope is back on the pier after Noel's miss. Hope Noel does not mess up your weekend!! - cheers - Rod George Normandin wrote: This is taken with an STL-1301E thru an OGS 20-inch RC Cass working at around F/5.

VERY nice image, George! I like the sharpness of your stars... :-) Mine are not so sharp (yet :-) Gordan, The stars look sharp because the camera under-samples at F/5. The pixels are too big. It is intended to be used at the longer F/8 prime focus. George N |

I got stuck with giving the program at Kopernik Observatory last night and after we got rid of our 50+ attendees (around 10:30 pm) the clouds started to roll in from the south east. A quick look at weather.com and we knew the night was done for. ( It is nice to have a high-speed net connection in the dome - even if it does show that a tropical storm is on the way. ) George N |
