Layering new with old…

I’m on the fence about heading back out tonight for some wide-field imaging. I have this idea about going deep RGB on NGC7000, but not shooting full spectrum red at all. Shoot Ha for the red channel and standard green/blue all binned 2×2 and then shoot a luminance set binned 1×1 and see how that turns out. I think I could pull it off in one night because of the lens speed, but it’s a big effort to pack up and drive an hour+ each way a second night in a row.

Disappointed that I didn’t capture what I set out to last night, I was cold and done with time to wait while another imager was finishing his run of 15 minute subs, so I set up a short series of 5 minute luminance subs while we waited for our window to tear down. I registered those this morning and manually integrated them, then took an already integrated OSC data set from October of 2014 that I shot with a stock DSLR and converted both from linear to non-linear and did a simple LRGB combination folding the new lum data into the old color data. I didn’t do a color calibration or anything, so I’m certain there are far better ways to do this… I was just messing around and didn’t want to waste the data. It didn’t turn out half bad! Once I develop my post-processing Fu some more, I would like to have a catalog of “good” data that I can keep adding to over time.
