yes, it is possible. I don't like it very much because of the difference of visibility of each night and centralization in the FOV. It demands much processing effort.
I thing that maybe I haven't camera to get good image of this galaxy. I have good resolution: 0.8 arc seconds, but when I call the faint information, the stars become more fat, and I presume all the other thin details.
Perhaps a CCD with similar resolution, instead of CMOS, will capture the faint details with more sharpness.
Not only noise issue. I have problem with light pollution as sky glow. With 1600 the time of exposition must be small.
With small (7.3' x 1.2') and faint objects the sky glow is the worse occurence. It merges with the object.
I think that with much more low ISO subs I wil get better result than high ISO.
Its magnitude is about 11 - 13, but with galaxy this is relative. Galaxy isn't nebula. The interior details are very small and with very little difference of magnitude.
