Description

This was my other "first light" target with the mono+cooled camera. Again, my guider was not talking to my laptop so all of the subs were unguided and only 60s. I took a lot more of them, though, than of M20 - nearly 1.5hrs total for luminosity. I can't wait to get the RGB data on this - just have to wait for the moon to go away and the clouds to stay away.

I'm also putting up a direct comparison image of my first time on this target.

This nebula is about 1300 ly away, so light left this thing around the year 700AD. It was about this time, or just before, that the city at Teotihuacan collapsed. Scholars think it was the result of internal unrest.

Description: Here's a comparison of the two versions I have of this. 2 years, lots of hardware changes, 60 minutes. I'm looking forward to making the color version.

Description: Increased saturation of the image. I think this is better - there was more color in there that StarTools wasn't quite pulling out. GIMP pulls it out, though.
