Do folks do LRGB lunar?

I've only ever used mono but notice that some folks' lunar images can have some colour in them.

Could I reuse by Baader LRGB that I used for deep sky and redeploy them for Planet/Lunar AP?   I note that some folks use an IR cut instead of the L channel?  Which one? OR is L a waste f time and should just be RGB?  I have a mono high speed camera (ASI 1174).

Many thanks, Steve

It might be worth trying a long wavelength as luminance, say red or Ha.

I'm sure they'll work Steve, when I first got the Esprit150 I used my ASI1600 with ZWO RGB on the moon and planets with some success using a 2x extender. I didn't use L as I'd read somewhere that the narrower the band the sharper the image.  Easy enough to experiment though as exposure times are short and you can catch the Moon between the clouds.  Have to say though that I didn't spend long doing it that way and went back to mono Moon through Red and planets with a colour camera/ADC as it was easier to process.

Do you mean an IR pass filter for the L channel as a normal L filter is UV/IR cut. ? I've used a Baader 685nm IR Pass filter as a luminance which worked well on the moon but was no good for planets with a powermate as the image was too dim and a long exposure was necessary which defeated its purpose. With a larger aperture scope it could do well on planets too. Focusing with a Bahtinov mask was a bit tricky as only very bright stars and longish exposure gave a useable focus pattern.

I have used IR-RGB and LRGB on the moon. Works OK, but I do notice that you can get artefacts along crater rims along the terminator, caused by the order in which the different colour bands were taken, as the sun slowly rises or sets over the crater rims.

I have shot few color images of the Moon, but I used only RGB filters (the same I use for deep sky imaging - Baader CCD filters). I used G channel for luminance:
