Astrophotography – Imaging another galaxy – Messier 106

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.

Newtonian telescope vs blanked eye

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 blanked 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. Last updated: July 21, 2016 at 15:23 pm

See the Moon through my Newtonian telescope

See the Moon through my Newtonian telescope. This short video gives a first impression of how it is to look through a telescope. Since everyone already saw the moon without a telescope this is a good object because it allows an easy comparison. My telescope has a focal length of 1000mm. As camera I have use the DML31AU03.AS from “The Image Source”. More details on the equipment can be found on the equipment page. If you are currently thinking about buying your first telescope, maybe this simplifies your decision 🙂

Astrophotography – Imaging the galaxies Messier 65 & Messier 66

Tonight I imaged three galaxies at a time! The spiral galaxy M65, the “Hamburger Galaxy” NGC3628 and another spiral galaxy M66. All those objects are located in the constellation Leo. The picture is also available in full resolution here. For stacking I used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping.
