the Pleiades and the constellations of the south.

M27 Narrowband

If I ever needed proof of the difference in image quality one gets with a dedicated CCD vs a dslr, this has to be it.  I imaged in 2 colors, 8 3 minute frames per color (Ha and Oiii), mapped the Ha to red and the Oiii to green and blue.  The amount of stretching in photoshop was nil - just a wee bit to bring out the edges, but for the most part, this is how bright this appeared on the capture screen.

If that werent enough, I didnt stop there.  I re-mapped this into a Hubble Palette version.  Even more detail is visible!

Not bad for a 2-color image.  This narrowband stuff is turning out to be too much fun!  I still cant get over the fact that I did this with about 45 minutes worth of camera time.

This is a picture of last year's M27 taken with the dslr. 

Although not a BAD image, there was a lot of image stretch to bring out the fine detail, and lots more imaging and processing time.  Of course, this is a standard RGB using the dslr.
