Here are some
published photometric measurements for surface magnitude:
R1: Blue=26.2, Visual=25.7
R1 dogleg: B=26.6, V=26.0
R2: B=26.7, V=26.2
R4: B=27.6
These are just the peak surface magnitudes - most of jets' area would be fainter than that, as you predict. The paper says that the R1 and R2 jets are blue in colour near 1097, but they couldn't measure any colours further out or in the dogleg.
I'd argue that the R4 jet is teetering just below the noise limit of your image (I couldn't see it at all even with the label at first; but now having read a few papers and studied some deep images I think I can see it... hmmm).
Getting down to mag 26-27 with 8 hours of imaging is bloody impressive
Are you suuuuure you don't want to go mega-data on this?
