My target tonight again was our neighbour galaxy Andromeda (M31). I like this object because even after a short exposure time and even with light polluted sky amazing structures become visible. In September 2012 I already took a first shot of M31. This time the result was even better (even without using any flat-field images) and I decided to put it into “My top Astro-Pics” section. It is also available in full resolution. For stacking I used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping.

After the camera went out of focus last time, I decided to give NGC6995 another try. This time the focus is much better. Here is the result 🙂 The image is also available in full resolution.

The Owl Nebula (M97) (the little blue circle) is a planetary nebula located approximately 2000 ly away in constellation Ursa Major. It has already been discovered in 1781 by Pierre Méchain – a French astronomer. The cool thing about it is that there is a spiral galaxy M108 which is “close” to that nebula – at least from our perspective.

In a clear night I was able to shoot this image. With 3j56m the total exposure time is relatively long compared to other images. I did not use any flatfield images for the post-processing. Based on that fact I am quite satisfied with the result.
The image is also available in full resolution.
Clear skies!
