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, 200x200 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 - 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 "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. 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.
