Isn't that the scene of Xandir's anal defloration ("Drawn Together")?

Speaking of...

As imgur disallowed bitcointalk, i decided to upload a fresh pic of one of my favorite deep space targets to talkimg.
NGC 2244 aka. Rosette Nebula (More, but maybe boring details below)


This time i used the new Autofocus, resulting in some more details and less blur in the original data. I also followed a EAA (Electronically Assisted Astronomy) approach of cranking up the camera's gain, which allows the total imaging time to stay low while collecting the same amount of light as in regular astrophotography. This results in more noise and shorter single frame exposure times. The two major caveats are reduction of dynamic, so stars are saturated earlier, as well as the very faint sky background structures (radiations) don't get through, because they drown in the increased noise levels. SNR and dynamics vs. convenience. This works well with bright targets and star structures, without much nebulosity in the background. I had to stay down to 30 seconds of single frame exposure time, while 20 would have produced nicer stars, also the power plug of the telescope mount fell out, because the cable got caught by an adjustment screw mid session, i recognized it 35 minutes later, stopped the session and threw away 71 of 236 frames. Total image count should have been 240, i decided to increase the amount of images because the night was so clear, when i discovered the accident. Still, the level of (foreground) detail in the processed result is about the same as in a high-definition astrophotography session of about 4-5 hours in duration. The target is of medium brightness, at the edge of being suitable for the high-gain/short exposure EAA approach. Enuff of the blah, have a nice day  Grin
