I am happy to present M106 from this year as a result of a great collaboration of 4 imagers namely
@Francesco Meschia,
@pmneo,
@Andrew and me.
Together we sampled more than 250 hrs of light in 4.319 images over a period of about 2 months. We used similar 130/910 mm apo refractors and 3 of us shot with an ASI2600mm pro, one used an ASI294mmpro. My version is an HOLRGB combination and same as in my last years M 106 I concentrated my processing on getting the phantastic narrowband features of M 106.
The image consists of the following data
L 692 x 90s = 17,3h
R 475 x 60s = 7,9h
G 500 x 60s = 8,3h
B 499 x 60s = 8,3h
OIII 183 x 300s = 15,3h
OIII 358 x 600s = 59,7h
Ha 513 x 300s =42,8h
Ha 396x 600s = 66,0 h
with a total of 3616 images and an overall exposure time of 225,5 h.
The deep OIII data reveal a smaller OIII jet left of the main Ha jet in the image. It is also present in the Ha data but more weak so that it appears blueish in the combination. The main Ha jet is split in two so there are 3 jets visible in that part of the galaxy. On the opposite side of M 106 a “waterfall” of Ha emitting material is flooding from the galaxy plane and also forms a thin jet-like structure.
The heap of data lead to a very deep image with a lot of tiny background galaxies. For example there are galaxies like PGC2299122 that are in a distance of about 3.8 Gly. I cannot calculate an age or distance for red-shifts > 1 but it is noticeable that according to Aladin and the SIMBAD database the faintest galaxy in the FOV has a red-shift of 1.78163. And there are numerous Quasars which are supposed to be way more far away than 10 Gly from us.
