I have a trip planned to a dark site coming up in a couple weeks and want to plan out what I am going to do.
I have read that some people use 2x2 binning on the RGB filters and 1x1 on the L filter.
Does anyone have any pointers to reading materials on when this is appropriate and any other related details?
I am imaging with a C8 + F/6.3 reducer (1280mm), with ASI294mm mono camera + Baader LRGB filters
Binning color seems to go in and out of fashion. With your image scale it makes a whole lot of sense. I've done imaging with it, and without it.
Madratters point is that you need not bin CMOS in hardware when you image. You can just resample your data in processing. For CMOS those things are equivalent, mostly. You don't get the read noise benefit with CMOS that you do with CCDs, but you still get the more important improvement in signal to noise ratio by binning (or resampling) 2X2.
The theory is that you can use lower resolution for RGB data in LRGB imaging. Because your eyes see detail in the L, not the RGB. You're basically just painting the L with RGB.
Some people like doing it, some not. Give it a try, see what you think. You can do it by resampling in processing, that's readily reversible.
