Astrocups – The perfect Christmas present for Astro-Fans!

Merry Christmas to everyone! Well, if you are still looking for an astronomy related Christmas present you are¬†probably a little late this year ūüėÄ But maybe you just found something for next year… Using some of my best images I composed some fancy “astrocups”. Next time you prepare for your star-gazing event you should have one of these with you! To produce the cups I used the service of http://www.luebeckgeschenke.de/ (more exactly here). The images are designed for the “standard cup (white)” and the “black cup” with a dimension of 1496 √ó 630 pixels, 200×200 ppi. Here are the three best ones so far:

1. The “Black Hole Cup”

This cup symbolizes a black hole just like the center of M51 Рthe Whirlpool Galaxy which is printed on the cup. This image is the outcome of a long night in May 2015. Personally I think this cup is best suited for black coffee…

2. The “Good night Cup”

The¬†“Good night cup” has images of Jupiter, Saturn, our moon and the sun. The¬†photo of the sun has been taken during the partial solar¬†eclipse in March 2015. The moon is a small version of the moon mosaic recorded in July 2015.

3. The “Star-gazer Cup”

Finally, the Star-gazer cup reminds me on the time I spent on La Palma. The cup is white since the sky is already dark enough there…

Clear skies!

Imaging the Whirlpool Galaxy (M51)

Today, after a long long cycling tour the weather forecast made me smile ūüôā 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.

Whirlpool Galaxy (M51) with DMK31AU03.AS

Tonight I imaged my first galaxy using my DMK31AU03.AS! To me this is absolutely¬†fascinating! ūüôā I also published my image here. Here are some more camera details: Auto max value: 1/15 (auto), Auto reference: 126, Brightness: 15, Gamma: 100, Gain: 930. For stacking I used giotto V2.21.
