Astrocups – The perfect Christmas present for Astro-Fans!

Happy Christmas to everyone! Well, if you are still looking for an astronomy related Christmas present you are┬áprobably a little late this year ­čśÇ 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 (more exactly here). The images are designed for the “standard cup (white)” and the “black cup” with a dimension of 1496 ├Ś 630 pixels, 200×200 ppi. Here are the three best ones so far:
1. The “Black Hole Cup”
This cup┬ásymbolizes a black hole just like the center of M51 – the 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…Download

2. The “Good night Cup”
The┬á“Good night cup” has images of Jupiter, Saturn, our moon and the sun. The┬áphoto of the sun has been taken during the partial solar┬áeclipse in March 2015. The moon is a small version of the moon mosaic recorded in July 2015. Download

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 ­čÖé 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.
