Tonight is probably the first perfect night for star-gazing for a very very long time! The sky looks clear and the forecast also looks very promising! So lets see which surprises this night is going to have đ

While debugging my astro-tools software taking images with my Atik383L+ I focused on an antenna to test the taking of sub-frames in combination with different binning settings. While testing suddenly some birds paid a short visit đ
This is a photo taken from a less popular region in constellation Cepheus. On the bottom right is the spiral galaxy NGC6946 also known as Fireworks Galaxy. On the top left is an open cluster with the great name NGC6939. The seeing was ok but could have been better… like most of the time đ For more details on the equipment take a look at the equipment page. For stacking the images I used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping.

Tonight I imaged the Cocoon Nebula (IC5146) – a reflection / emission nebula in constellation Cygnus. The cluster is about 4,000 ly away. The seeing was great and the guiding with PHD worked perfectly well. I was a fantastic summer night.
For stacking I used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping. The picture is also available in full resolution here.

Behind the unspectacular name NGC6914 a nice emission nebula in constellation Cygnus is hiding. To me the nebula looks a little like a dark monster with two deep blue eyes in the center of the picture đ
