In July 2012 I already imaged M106 with my DMK31AU03.AS camera (no guiding). Now I wanted to try the same object with the Atik383L+ camera to see the difference.
There are additional galaxies around in that picture – NGC4248, NGC4231, NGC4232, NGC4217 and NGC4226! Here is a full resolution image which better shows the details of the image.

For stacking I used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping.

I think sometimes it is hard to get a feeling for the magnification of a telescope – especially when you are relatively new to the topic (like me). So I decided to make a test with my naked eye vs my Newtonian telescope (focal length F=1000mm) in combination with my Atik383L+ camera to get a better idea of it’s magnification. The pixel size of the Atik383L+ is 5.4um x 5.4um. So the overall magnification factor should be about 107x.
To me the result is quite impressive. Talking about a magnification of about 100 is one thing – but seeing it is something else. When looking at the sky at night I think the applied magnification is not so obvious. I think this test image helps to get a rough idea.
Clear skies!
