This 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.

C/2011 L4 (PANSTARRS)
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.

The Milky Way
Lens: Tokina AT-X 12-24 f/f
Camera: Nikon D200
Exposure: f/4 15s ISO 1600 – 5 images, stacked in IRIS
Date: 7th August 2010
Recently I spent a night in the Alps at 2000m height. I slept outside in a bivouac bag and enjoyed a very dark sky.
I took the picture above with the camera on a small tripod, and made 5 exposures which I later combined into a single picture using IRIS.
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.

Yet another M42 image…
After a very long summer-break in Astrophotography, I found myself with time on hand on a clear evening. After I did a series of 4 300s images for the Plejades (see below) I set the scope up to capture a few light frames on M42, the Great Orion nebula. But while I was sitting in the living room trying to get warm again, watching the Soccer Champions League, the D200’s battery ran empty, and I ended up with only one long exposure. I used the single 300s exposure with a much shorter exposure to get some detail in the very bright center of the nebula to get this picture.

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
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.
