Since we now receive new pictures of NEOWISE daily (from our employees as well as our customers), we have decided to only maintain the following picture gallery. Information about the comet as well as search maps can be found at various other places on the net. Here you see only new beautiful pictures and videos, which we will be permanently extended. Some of the pictures we already showed in our original NEOWISE article (with an update).
If you have any further questions about image data, please contact us - we only mention the copyright holders and the date of recording of the respective images here.

THE STORY: In the Heart of M42
When we were still shooting on film, it was just like today: The Orion Nebula has always been on the most-wanted-list of practically every astrophotographer. This starts with wide field shots and ends with detailed images of the surroundings of the trapezoid stars in the heart of M42. This region of M42 is much brighter than the faint surroundings, and this enormous dynamic range makes photography especially tricky. The structures require a long focal length and a wide aperture to let them shine.
For my imaging I chose Celestron's C14 EdgeHD, which is still compact despite its size and therefore doesn't require an gigantic mount. At an f/ratio of f/7.6 with the special reducer designed for full-frame cameras, I...

Update 09.07.2020: See the new Comet-Gallery with lots of images and videos
UPDATE: The latest images fo comet NEOWISE
During the night of 7-8 July, the whole of Central Europe had the special opportunity to see two rare celestial phenomena simultaneously. Around 3 o'clock comet NEOWISE climbed over the horizon. Not much later, the sky behind the dark cloud bank just below the comet suddenly became much brighter.
As it turned out, the sun began to illuminate noctilucent clouds at a height of 80km (four times as high as normal clouds), which consist of frozen meteor dust. These rare clouds became more and more dominant and finally covered the comet until it was hardly visible around 4 o'clock.

Venus as a ring – how can that be?
During the last days several customers have sent us some very interesting photos of Venus, which we do not want to withhold from you. They show the planet as a very narrow sickle or even as a ring. This effect can only be seen on Venus by observers on Earth, and it is only visible when Venus is in lower conjunction (www.wikipedia.org/Aspects_of_Venus), i.e. when Venus is located between the Sun and the Earth..
How does the effect come about?
The planets Venus and Mercury are the only two so-called "inner planets": They are closer to the Sun than the Earth and orbit the Sun within the Earth's orbit. That‘s why they are the only planets that...

Darkness Became Light! ... A Quantum Leap in 36 x 24mm at 61.1MP?
In recent years, color cameras have become increasingly popular. A reversal of the trend is not to be expected. One reason for this is the ability to capture weak structures in deep-sky objects even with moderate exposure times. Developments in CMOS sensors and recently the BSI sensor technology have played a decisive role in this. In addition, both quantum efficiency (QE) and full-well capacity increased, noise was reduced, pixels became smaller and smaller, and dynamics increased with almost every new sensor generation.
What happens when all these developments see the light of the stars in a new camera like the QHY 600M with a black and white sensor?
I had asked myself...

Please note: We wrote the following report of our dome assembly in January of this year months ago, but had to wait for picture release from NASA and the University of Texas, which was delayed for understandable reasons given the current situation.
Located in the Texas Davis Mountains on Mount Locke at 2,100m is the famous McDonald-Observatory.
The University of Texas owns and finances the site.
Due to the current construction of SLR stations at NASA for Space Geodesy Satellite Laser Ranging (SGSLR), a 4.2m high-speed dome from Baader Planetarium was installed here in January 2020. This is the second system of its type after the 4.2m Highspeed-Dome at the Goddard Space Flight Center, which was installed in April 2019.
For over 40 years, NASA's global network...

THE STORY: Veil Nebula and Planewave CDK14 – it can be so easy
The "Veil Nebula" NGC 6960 is a remnant of a supernova explosion that occurred 8000 to 10,000 years ago. With a length of over one degree it is huge - and the Cygnus loop, to which the Veil Nebula belongs, is even larger at around 2°! For this picture, images from two nights were combined, whereby subframes with seeing values worse than 2.05" FWHM were not used.
Now, I have to admit my preference for long focal lengths right at the beginning. As far as conditions allow, I want to get details out of the pictures - and since I have a location that often has good to very good seeing, I...
