Leon Choin's Astrophotography
[ LCAS ]

This image is a combination of a wide field image of M42 from Leon Choin, and an image of the core area of M42 from Dave Wagner taken from separate sites on 2/2/2005.
Widefield M42 - One jpg fine image taken on Canon EOS Digital Rebel, 25 second exposure, ISO 800, with prime focus on a 8" Konus newtonian.
M42 Core - Taken on a Nikon D70, prime focus, 10 second exposure, on an 8" Celestron SCT. The 11 raw images calibrated with 3 dark frames, combine in Images Plus. The Widefield and Core final images were resized, aligned, rotated, then scaled and combined using the core image as filtered and mask, the widefield as the source image in ImagesPlus.

This image was the overall winner at the club's November 2004 photography contest.

All aurora photos where taken between 01:30 and 02:45 on 11-8-2004.
The camera was a Pentax K-1000 on tripod, 50mm lens set at infinity f/2.8, 35mm Fugi film 100 ISO. Most of the pictures are 30 second exposures.

The above picture was featured on the NBC5 10:00 News on 11-8-2004 during Brant Miller's weather spot.

The above picture won the photo of the month at Wolf Camera in Crystal Lake this month. It was a 20 second exposure.
