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.
