Description

While I was chasing dark nebulae with the RASA, I has my double Esprit rig aimed for two nights on this triplet of galaxies (actually much more in there than a triplet). I collected 6 hours of Lum with the Esprit 150 and ASI6200, which did bring out a bit of Integrated Flux Nebulosity (IFN), the dusty stuff illuminated by the glow of our own galaxy. I collected most of the RGB during 4.45 hours with the Esprit 100 and ASI071. However, particularly the red signal was quite low so I added 2.4 hours of old DSLR data I had collected with my Canon 60Da and Explore Scientific 127ED back in 2016. Seeing could have been better. At some point I should get back to these objects for more Lum and then also some Ha data.
