A late friend of mine owned a Zeiss AS 63mm lens, it took me a while to figure out all the details, as it is not mounted in the original cell, but in a custom machined one, and the tube loooks like it is self-built too.
In the process of establishing the quality of the lens I took these images with a QHY5L-IIc camera in prime focus configuration. As the conditions were very changeable because of passing clouds, the brightness of the images had to be adjusted individually, color saturation has been enhanced.Read More
In 1998 I created this GIF animation showing the effects of the earths atmosphere on an image of the moon:Read More
I used the 127mm f/8 refractor together with a Nikon TC20EIII teleconverter on the Nikon D750, resulting in a focal length of about 2m. The picture is a combination of 24 exposures of 1/20s. First I aligned the pictures using PIPP to be able to stack them in AutoStakkert 3. Sharpening was done in Registax 6. In Photoshop I followed Dylan O’Donnell’s process for HDR moon images by combining the stack with a single 20s exposure using a layer mask in Photoshop, some final touches were added in Lightroom.
Yesterday I took out the 200mm reflector in a very cold wind to take some close-up images of the moon. I am quite happy to have captured the rille in the alpine valley quite distinctly.Read More
When my wife noticed the beautiful thin crescent moon in a gap in the clouds I rushed to the deck on our roof, to take a picture of the conjunction of the Moon and Jupiter. At first I went bare-footed, but after a few seconds I couldn’t stand the snow under my bare soles, and put on some slippers. But I was still only wearing my sleeping attire, boxer shorts and a worn-out T-shirt. Temperature was -5°C.Read More
The longest lunar eclipse of the 21st century took place during our vacation in Corsica, here are some shots taken from the beach:
Since this was a camping vacation I only had minimal gear with me, a Sony RX100 IV compact camera, and my wife’s Olympus E-PL5 with the kit zoom lenses. The 40-150mm is equivalent to 300mm on full-frame cameras, so the close-ups are cropped heavily.
Last night I photographed the same lunar regions through 3 different telescopes:
- Astro-Professional 80mm ED f/7
- Astro-Physics 127mm f/8 refractor
- GSO 200mm f/5 Newtonian
