On Wednesday, 9th January I imaged the open cluster NGC2175 the first time from La Palma. The seeing tonight again was very good - around 1.5~2"!

For post-processing I used the free software DeepSkyStacker and GIMP.

The full resolution images is available here.

Clear skies!

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. Btw: Happy Easter! 🙂 Last updated: March 25, 2016 at 9:41 am

Star-gazing live in Böblingen - 2015/11/11 - IC342

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 🙂 The object for tonight is IC342. It is a spiral galaxy in constellation Camelopardalis. The galaxy is about 10 million light years away from us. In other words that means the light traveled about 10 millions years before it finally hits my telescope 🙂

In fact, this object is very weak. A brightness of about 12mag is very close to the limit I can image with my telescope here from Böblingen. Still I think it is worth a try. The first frame just came in. It has been recorded with binning 1x1 and an IR filter. The exposure of this single frame has been 800 seconds - actually one of the longest I ever did. I am not so sure if this is a good idea - especially regarding the final image quality... lets see....

The seeing is above the average this time. After a while, 11 IR (800s, 1x1 binning), 9 R and G frames (200s, 2x2 binning) and 8 B frames (200s, 2x2 binning) have been successfully captured! I will post the result pretty soon. Good night everyone!

Hello again! One short night later I finally composed the collected frames using DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping. Actually, I am very satisfied with the result. Unfortunately the object is not that colorful but the structures are quite good visible. And again, I am surprised that it was possible to image a 12mag object from a city like Böblingen with an cheap 8" Newton telescope 🙂 A full resolution image is available here. The most important image data can be found in the table below.
