Read MoreThis evening I did a quick test under the stars to see, how iAstroHub 3.0 works with my setup.
Apparently it works quite well, though I need to test with longer exposures.
It looks as if 2013 will be a good year for comets. This spring Comet Panstarrs is visible in the darkening sky after Sunset and in December comet ISON should put up an even more impressive show.

This is a two-frame mosaic taken with a DMK21 camera and an Astro-Professional 80mm ED refractor:
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:
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.

After a very nice display the day before, another solar eruption triggered an even more impressive display
All images were taken with a Coolpix 4500 camera, either with the wide-angle converter, or the fisheye converter.
