M82 - "The Cigar"

M82 is part of a galaxy pair in Ursa Major. It is about 12 million lightyears away. It doesn't have the usual shape that we are used to see for galaxies. And there seems to be strings of gas flowing out from the galaxy. It is therefore called an "irregular galaxy". On January 24th, a supernova was detected in this galaxy. I took a photo of the galaxy a week before. But due to terrible weather in the weeks to follow, it took a long time before I was able to see it in an image myself. I decided to take a longer exposure of the galaxy using a remote telescope.
Tech details : 20" F/6.8, FLI PL09000, 3x3 binning. Exposure : Luminance 20 min, R, G & B : 5 min 20 sec each. Stacked in DSS, processed in PS.

NGC4565 - The Needle

This is one of my favorite galaxies. An edge-on galaxy in Coma Berenice. I have tried my luck at this several times, but this is the first time with a bigger scope with longer focal length. It is obvious that the oversampling in this picture does it good. Lots more detail than I have previously been able to aquire. And in such a short exposure. But I guess that is from the fact that the camera uses 3x3 binning... Should be a lot faster then.
Tech data : FLI PL09000 camera, 3x3 binning, Luminance : 15x50 sec exposure, RGB : 5x40 sec exposure. Telescope : 20" F/6.8. Stacking in DSS, processing in PS.
