NGC3169 and NGC3166 - Stellar Siphon

I finally got around to "finishing" this image by collecting the remaining RGB frames a couple nights ago. Seeing was as terrible as I've ever seen it (not to mention brutally cold). Luckily I was mostly shooting color so the impact was negligible. I did collect almost 3 more Luminance hours but it was just plain bad with a FWHM almost double the original frames. The seeing wasn't so great the first night out, so I'm sure there's a bit more resolution I could still squeak out of this system. Regardless, I combined the RGB with only the original L subs and you get what you see right here. The color is very subtle in most of the areas of these galaxies which is pretty cool in it's own right.

I decided to upload this as a separate image since I think the "luminance only" seems to stand on its own pretty well. Enjoy!

Rev A - Original L, Added RGB

Rev B - Increased contrast, which to my eye makes for a more pleasing version. But, you can draw your own conclusion, I suppose.

Rev C - I've been getting several queries about what the raw data from the camera looks like so here's a look at the 39 luminance frames (scaled to 50% due to smooth playback) complete with an asteroid capture seen moving between NGC3166 and 3169:

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
