Binning calibration frames

[Marky1973]

Okay, I've not posted much for ages, so its time for a stupid question....

I presume that, when binning RGB light frames, I need to also bin the FLATS, BIAS and DARKS? Or does it matter if you can register/rescale the subs (although that sounds like making work for yourself).

Daft question, but I'm building up a library, so just checking! :-)

Cheers

Yes you'll have to bin all your calibration frames.

Well, you do when using deep sky stacker at least.

This is how I do it, and that's not to say it's it's the right way, but it works for me. I shoot my calibration frames at full resolution then re-scale them in PI to 50% size for bin 2, and then use them to calibrate my bin 2 RGB subs. I then rescale the binned lights after calibration to match my full resolution Luminance.

Now I image the correct and purists way to do it is to shoot binned flats / bias and darks, but why bother when you can cheat!?!

Sounds like I am safe either way then! :-)
