Hello,
this is M109 in Ursa Maior.
Imaged in March and April 2015 with the Moravian G2-8300 at my 12″ f/4 Newtonian with L:R:G:B=540:210:210:210 minutes. Subexposures were 30 minutes for luminance and 30 minutes for RGB.
In February 2014 I imaged the same galaxy with L:R:G:B=160:160:160:160 minutes. Subexposures were 10 minutes for luminance and 10 minutes for RGB.
So now I got a total exposure time of 30 hours.
Reinhold
