The Moon 2019-05-10

The Moon 2019-05-10, the bright side is stacked from 24 exposures of 1/20s, the dark side is a single 20s exposure. Processed with PIPP, Autostakkert, Photoshop and Lightroom.

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.

M78 and the Monkey’s Head

Barnard’s Loop, Open Cluster NGC 2112, Reflection Nebula M78, Reflection Nebula NGC 2071, 62x120s (2h 4min), Astro-Professional 80mm f/7, 0,8x Astro-Prof. Red., Nikon D7000a, Optolong L-Pro Filter

Even after more than two hours of exposure the image of the reflection nebula M78 and it’s surroundings is quite grainy. This object needs much more exposure. When pushing the raw files to bring out the faint nebulosity the background becomes a bit streaky, therefore I kept the image quite dark.

The Horsehead nebula (again)

B33, The Horsehead Nebula, 50x120s – 1h40m, ISO1600, Nikon D7000a, 80mm f/7 ED-Refractor, 0,78x Reducer, Baader 2″ H-alpha Filter 35nm

After a long spell of clouds, snow and rain, clear skies have returned. Apart from the streak artefacts in the background I like this image a lot, this is my first properly focused image with the Baader h-alpha filter.
