I took some LRGB data of NGC1313 last dark of moon, but was too embarrassed to post it here, since the L (and some B) was badly affected by star halos. This is a shame because it a pretty funky train wreck of a galaxy.
Then
@Michael Feigenbaum gave me an idea (thanks Mike). He adopts a 10:1 L:R/G/B ratio, much higher than the canonical 3:1. I thought I could give this try, particularly on my L data - which was largely junk. Rather than use time to get more data (weather still not cooperating down here), I decided to use aperture and not time to boost my ratio.
With 75-90mins in each of R, G and B, I obtained 70mins on the 500mm ASA Newtonian at Chilescopes, using aperture to give a 5:1 ratio. With pixel scales between the Chilescopes Newt and my RC8, it was also test (at least for me) the contention that RGB data can be taken binned, since I had taken my observations at bin x 2.
While it won't win any awards, I am now not embarrassed to post the result. The Feigenbaum Protocol (sounds like a 70s movie) worked well, and the lower-resolution RGB data didn't appear to impact visually on the resolution of the L data. Even the diffraction spikes lined up. The blue holes from my home observatory data still show up, but I didn't have to boost the saturation at all to get the colours out.
[I also took some RGB data with the Chilescope , but didn't use it. I didn't have enough frames to take out some of the CCD artefacts.]
L 13 x 300 x ASA500
R; 18 x 300 x RC8
G: 17 x 300 x RC8
B: 12 x 300 x RC8
