Description

Some time ago the remote scope in Spain took 17 subs at 10 minutes long each of R, G and B. It also took 23 subs in L at 10 minutes each in length, as well as 9 subs of Ha at 10 minutes long each. I finally managed to process this, and I am pleased to have been able to pull out from the data the integrated flux nebula (IFN) - at least a little bit of it, anyway. The IFN is an extremely faint glow caused by the combined light of the stars of the Milky Way reflected and re-emitted by interstellar gas and dust.
