9-27-2007 The Ring Nebula and Uranus



Clear skies again tonight, but lots of light from the moon. Decided to try the Ring Nebula since it wasn't very clear last time. After looking at other's photos, I realized I was not in focus.




Ring Nebula:


This time I only used the DSI without the barlow--remember I have the f/6.3 reducer


15 s exposures about 30 images LRGB.




I have no clue how to do color though....so here is my B&W taken from 30 Luminance images. All processing done in Registax4.




I've tried using some tutorials from http://www.cloudynights.com/, but I can't seem to figure out how to merge the RGB channels. I would like to figure out how to do it though to see what color my ring image has. When I open the color ones in Registax, it thinks they are black and white...to tell you the truth, I don't see any color myself. I suppose I don't truly understand how a monochrome camera works.


Uranus was not a success...I was trying to underexpose it, but I didn't really capture the globe or any moons. It was easy to see in the EP as a green globe, but came out almost starlike in the CCD. I will post a pic just to show how bad I got it. I def think a 5x telextender would help get the exposure and detail right.

Hopefully I will have better luck next time with Uranus. I think I am getting the focus on DSO's better though, as evidenced by the Ring. This imaging is a long slow road!
