Blood moon at Lake Constance

Today there was the chance to observe a total lunar eclipse here at Lake Constance! Under a clear sky and at about 28°C after 10 o'clock in the evening the blood moon was perfectly visible. Right below the moon planet Mars was shining brightly. A lot of people were interested in seeing this phenomenon.

I recorded 2 pictures - one with the Fujifilm X-T1 and one with a Canon PowerShot SX710 HS. The zoom of this camera is extraordinary! With a small tripod and an exposure time of just 1 second I was able to get this result. Find the results of this evening below.

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 probably a little late this year 😀 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 × 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!

Creating a moon poster - Or: How to record a moon mosaic

The DMK31AU03.AS camera only has a resolution of 1024 x 768 pixel. To create larger images one can record multiple regions after another (a mosaic) and then put them together to one big image. This can for example be simplified using the "EQ6 Mosaic" tool.

This tool allows recording defined regions after another just with a few clicks. Once you have defined the pixel size, the focal length of the optics and the desired overlap you are ready to go.

The image on the right consists of 6 single images. Each image is the result of an videos á 400 frames (@30fps). Each video has been stacked using Registax. Then the single images have been put together using gimp.

Here are some image details
  • Date: 2015/07/25
  • Location: Böblingen / Germany
  • Camera: DMK31AU03.AS
  • Telescope: 8" f/5 GSO Newton
The image is also available in full resolution here.

See the Moon through my Newtonian telescope

See the Moon through my Newtonian telescope. This short video gives a first impression of how it is to look through a telescope. Since everyone already saw the moon without a telescope this is a good object because it allows an easy comparison. My telescope has a focal length of 1000mm. As camera I have use the DML31AU03.AS from "The Image Source". More details on the equipment can be found on the equipment page. If you are currently thinking about buying your first telescope, maybe this simplifies your decision 🙂
