M1 - Last one from Marathon night

[Brian DeJong]

Here is the last one, I followed Steves tutorial on this one more closely thatn the others, and I think I need to go back and do a better job with the previous ones.

Stack of 15 out of 50 images,  aligned in Photoshop CS, adjusted per tutorial.
LX200 @f5.5 or so, hard to judge with the GEG and the extension tubes,  If anyone has a way of calculating I would love to hear it.  D300 at ISO 1600, 114 second exposures.
