M42 - The Orion Nebula
Object: M42 & M43

Date: December 9, 2001 & February 17, 2002

Exposure: 4x 35Min & 2x 20Min

Film: Kodak LE400

Equipement: 10" Meade SCT OTA w/GEG at f/7.5 on Losmandy G-11

Guiding: ST-4 (A3's)

Hardware & Software: Multiple scans of each exposure were created with my HP S20xi film scanner and Hamrick's vuescan software. The scans were registered and stacked using Registar. The resulting image was processed using Picture Window 3.1f.

Image Info: I am becoming more pleased with this image as it developes. Also I'm proving a hunch that one can extract a lot of information out multiple exposures when taken under 4.0 mag skys. I figure that if the CCD folks can do it, I should be able to also, just not as quickly. There is a lot of grain that seems to be visible in the image, undoubtably a result of the processing involved in dealing with the light pollution. The round cropping is a lame attempt to cover over the fact that the setup was so badly vignetted that it was beyond repair (at least I find it less distrubing this way). Click on the image for an older exposure of the same object.

This is an unprocessed "raw" cropping of one of the 35 minute exposures. This shows the effect of sky glow from my light polluted back yard.
