Looking at the Sunflower Galaxy ~8.7 billion Round-the-World trips away

36 million light years away – or 8.700.000.000 trips around the world! That’s the approximate distance to the Sunflower Galaxy which also has the boring acronym M63.

Tonight I decided to point my 8″ Newton telescope to this object to have a closer look. Even if I only had 2 hours of time I am still satisfied with the result. Personally, I think a sunflower looks a little different – anyway I like the shape and the structure of this object. M63 is located in constellation Canes Venatici and is not “so far” away from M51. Its apparent magnitude is about 9.3mag. Besides, I already targeted M63 a few years ago, but this new result I think is much better.

Star cluster Messier 44

Tonight was the first time since mid of November with acceptable conditions for astropohotography… I don’t like this weather… However, this night it was good – at least until about 3am. For stacking I again used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping. Happy Easter! 🙂

Astrohotography of Sh2-88 without H-alpha filter from Böblingen / Germany

The evening of 24th June 2015 was a warm and nice summer evening. All the clouds vanished and the forecast predicted a clear night 🙂 Since I didn’t image a nebula for quite some time I decided to image one this night. Recently I came across Sh2-88 which is an HII emission nebula in constellation Vulpecula. So this should have been the target for tonight!

I saw some great pictures of Sh2-88 before which have been taken using an H-alpha filter. Since I am not yet having an H-alpha filter I just decided to give it a try without H-alpha. Of course the nebula structures don’t come out as good as when using a such a filter. But I am still satisfied for a picture with just 5 IR frames. The seeing with my f/5 GSO Newton (F=1000mm) was around 2.1″ – so quite good for this region.

Imaging galaxies M81 and M82 from Böblingen / Germany

Messier 81 (M81) is a spiral galaxy about 12 million Lj. away from earth. Messier 82 (M82) – also known as Cigar Galaxy – is a starburst galaxy which is interestingly also about 12 million ly. away from us. Both objects are located in constellation Ursa Major.

For this picture 11 light frames (600s exposure time each) were averaged. This is twice as much as the typical frame count I usually have. Therefore, there is almost no visible noise in the the final picture.

The full size image can be found here.

Clear skies!

Imaging the Whirlpool Galaxy (M51)

Today, after a long long cycling tour the weather forecast made me smile 🙂 There was a good chance that most of the clouds will go away between 23:00 and 2:00. Since the moon is going to rise at 2:11am there is a short but sufficient window to do some CCD imaging. Since I only have free view to the south from home, the position of M51 is a quite good compromise. The seeing with my f/5 GSO Newton (F=1000mm) is around 2.7″ – so this is more or less average.
