M81 Redux

I re-did the first color image I have taken with the ST7, this image of M81 Bode's Galaxy. It could use some mor integration time for more color, but at least you can see the color. I had a lot of trouble with the CCD chip frosting over. I need to bake my desiccant plug, but haven't yet.

This is the very same image as posted below, just with different processing.

M82 - Re-shot with CMY filters

Here is M82 re-done with my ST7 and CMY filters. I had an old HA filter laying around, so I tried to blend it in as well.

Scope: Celestron C6S
CCD: ST-7 w/ Edmund CMY filters
L: eight 13 minute images
C/M/Y: four (each) 10 minute images
HA: six 13 minute images

M81 Done in LCMY Color

Not the best image ever, but this is the first real color shot I have done with My ST7. M81, shot with my new Atik filter wheel and my Edmund CMY filters. It came out a bit bluer than I expected. All images shot at F6.3 through my SC6 with 13 minute sub exposures. Stack: L=8, CMY=3

I could have probably brought out more color with a better CMY stack, but I was in a hurry and it was freezing out.
