With almost three hours of Hα-frames I wanted to enhance the glowing inner hydrogen gasjets near the core of M106. I discarded this data set because I failed to intergrate them properly into the RGB-image.
And here some older images of this object:

The bright barred spiral galaxy M106 is distorted by several smaller galaxies in it's vicinity. The outer spiral arms are rather smooth and seem to be depleted of dust and gas whereas the core shows quite a lot dusty structures. The northern spiral arm reaches far out into the direction of NGC 4248.
Over two nights exposures totaling 5.5 hours could be bagged.
The first night after several thunderstorms was extraordinarily clear, in the second conditions were mediocre at -2 - +4°C.
For comparison the same galaxy captured two years earlier in b/w with the Sigma 1603 and the TMB:
M106, NGC 4220, NGC 4217 and NGC 4248 (CVn)
