The Rosette nebula is a large and relatively bright emission nebula in the constellation Monoceros. Various parts of the nebula have separate NGC numbers and the embedded star cluster itself is NGC2244

Testing a new guiding setup

Posted on 27/02/2017 by philipp

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.

From Clavius to Schiller

Posted on 07/04/2009 by philipp

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 →

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

Posted on 07/03/2009 by philipp

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.

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.
