LBN 406 in Draco

Hard to believe, but there is a reflection nebula in Draco. LBN 406 is very faint and appears to be void of much color. Here it is -- not the prettiest but cool looking dust clouds:

BTW, this was my first attempt at L-OSC combine. I thought for my first OSC image I'd try an object that is really, really faint! Heck with the easy colorful targets For the OSC I de-Bayered into individual R,G,B files then processed as if they were taken with R,G,B filters.

Tom,
You do like to pick the hard ones to try out new things. grin I like the idea about separate RGB files. It kind of adapts the processing to a flow that you are familiar with.

The image came out really nice. Its a target I had not seen before.

That is an interesting shot Tom. Did you find the OSC to be more difficult, or pretty similar after the initial splitting of the colors?

That looks nice. Rather than the "difficulty" of processing, I am wondering about the relative sensitivity of the cameras. How does 4 hours with the one shot compare to 1.25 hrs each with RGB filters on a monochrome? Pretty close? Made and comparisons yet? (Sounds easier to take.)
