Comet C/2018 Y1 Iwamoto
Lunar Portrait and closeups
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.

The Horsehead nebula (again)
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.
Moon – Jupiter conjunction 03.01.2019
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.

On December 26th we were invited to christmas dinner at my sisters place. I brought the Vixen Polarie, the Takahashi FS-60CB and the Nikon D750 to do some astrophotgraphy during the evening.
The image above records some faint nebulosity across central Orion. From the horsehead nebula B33 silhouetted against IC434 to the flame nebula NGC 2024. In the upper left, the M78 nebula with its surrounding NGC objects is also visible. In the corner a hint of Barnards loops is discernible

Barnard 33 is the horse-head shaped dark cloud silhouetted agains the glow of excited hydrogen which goes by the name of IC434. To the left is the Flame Nebula NGC2024, which is an odd nebula, because it is orange, and apparently a mixture between reflection and emission nebula.

Today I used a break in the clouds to test how the astro-modified Nikon D7000 works with a h-alpha Filter. As the weather was very unstable, I didn’t set up the laptop for guiding, so some images were unusable due to trailing and passing clouds and full cloud cover at the end of the exposure resulted in oly 83x30s unguided exposures. Which way too short, but I am happy with the result under these circumstances.
NGC1499, Baader Planetarium, 1,25″ h-alpha Filter, 83x30s (41,5m) exposure, Astro-Professional 80mm f/7 refractor.
Two Nights, Two Scopes, Two Targets
In the first night I used my 80mm f/7 ED Apo for unguided 30s sub-exposures, in the second night, the 127mm f/8 Apo with 120s guided exposures…
M31, The Andromeda Galaxy, 199x30s, Nikon D750, Astro-Professinal 80mm f/7 refractor, processed in Regim, Fitswork, Photoshop and Lightroom
