A Moon Halo
A 22° Halo like this is visible when thin cirrus clouds made of ice cover the sky and the ice-crystals in the clouds are oriented properly.
To the lower left of the Halo you can see the constellation Orion.

From Clavius to Schiller
This is a two-frame mosaic taken with a DMK21 camera and an Astro-Professional 80mm ED refractor:
The very obvious crater in the middle of the mosaic is Tycho, it is relatively young and therefore the ejecta rays can still be seen brightly across the lunar landscape. Please note the dark area directly around Tycho which is also caused by ejecta of the impact.
To the lower right is the beautiful crater Clavius which has a nice curve of smaller craters on the floor. To the lower left you can see the very elongated crater Schiller which was produced by an oblique impact. Read More
From Tycho to Rümker
These images were taken on the 7th of April 2009 using my 150mm Newtonian telescope with a 2x Barlow lens, using a DMK21 camera:
Ariadaeus Rille
Today I took the first lunar images using my 80mm ED refractor, this is a 100% crop from an image I shot with my Nikon D200:
Gassendi, Clavius & Schiller
After showing Venus, M45, M42, Saturn and the moon to my in-laws I stayed on the roof for a little longer and took some AVIs using our club’s new DMK camera. I used my 150mm f/5 Newtonian telescope with a 2x barlow and a 90° prism (this gives about 2,7x). Again I had big troubles focusing because of my wobbly Super-Polaris mount.
Crater Gassendi and Mare Humorum:
Clavius, Kopernikus with a 110mm Schiefspiegler
110mm Schiefspiegler and QHY5 (ALCCD5)
These pictures were taken with Guntram Lampert’s 110mm Schiefspiegler on his rooftop terrace.
As this telescope has a dobsonian mount without tracking I was only able to take about 50 pictures while the
lunar featur we wanted to photograph was passing through the field of view.
