This image
was taken at the prime focus of my 8" f10 LX 200. The image is a composite of
one 20 minute, one 5 minute and one 2 minute exposures autoguided with the STAR
2000. They were first color
converted with the Starlight Express Pixcolm5
software, combined in MaxIm DL and then further processed in Photoshop. Total
exposure is 27 minutes. This image is a good example of what happens
when you attempt to image galaxies under skies that have a bright
background. NGC 4394 is listed at magnitude 10.8, so it should have been
clearly visible, yet the galaxy is just barely visible. This happened
because the bright sky background covered the dimmer galaxy and there
was no way to separate the light from the galaxy from that of the bright
background. I was able to use contrast stretching techniques to make
M-85 visible. Click
