RobH Posted May 27, 2009 Share Posted May 27, 2009 Hello all.I'm still bashing away at the rich region of Ursa Major/Canes Venatici at the moment and trying to grab as much as I can before the nights finally get too bright!M106, in Canes Venatici, is generally classed as an Sb type spiral and as such is similar to M31, as is easily seen here. There’s a fairly moderate black hole at the centre with a mass of 39 million solar masses which consumes about 1% of a solar mass per year. I first imaged this with a borrowed OSC camera in April, and took over 40x 6 minute subs, but wasn’t happy with the result, so I started again with a mono camera and filters. There’s a little Ha added to the red, but only at about 20% opacity, as I wanted to avoid the separate ‘jewels’ of deep red that I’ve had with my previous additions of Ha in various images. With this image, I’ve tried to keep a ‘natural’ feel…whatever that means! I started processing 3 days ago, but quickly found that the luminance was degenerating into too much noise in the faint areas when I stretched the image, so managed to grab another hour of data last night, which helped tremendously. It could still do with more and deeper subs though, especially in the colour channels. The core region is fine but there is some interesting blue in the spiral arms, which I’ve only just hinted at here. Anyway, it’s been a long road but I’m pretty happy with the final result. Imaged over several nights in May with my TMB 152 and Atik 16HR. Luminance. 54 x 6 minutes. Red. 20 x 3 minutes binned 2x2 Green. 17 x 3 minutes binned 2x2 Blue. 20 x 3 minutes 20 seconds binned 2x2 Ha. 10 x 6 minutes binned 2x2.Hope you like it CheersRob Link to comment Share on other sites More sharing options...
