As always, this was imaged from my light polluted back yard.
I cobbled together some old and new data for this one.
Attached is a mid-sized image, but a larger image and image details may be found here:

Thanks for looking,

Nice shot Dan. Very sharp.

Do you find the AO7 to be a useful accessory with your RCOS?

Greg.

Nice Shot Dan. I like the colors you got in the dust lanes. I am curious, you are shooting in some light pollution as you say, how did you divide the 8.8 hrs of luminance? Many shorter subs? I know this was a mix of old and new data, but in general, how many subs is the 8.8 hours?
