New Observatory

March 2015

I have set up the observatory for group visits and can accomodate upto 10 people with ease.

At last years ITT, Wolfi Ransburg talked me into buying a small refractor telescope for widefield photography. See details to the right.

I also purchased an iOptron SmartEQ Mount for mobile work but was not happy with its performance. I have upgraded to a HEQ5. Reports to follow.


News from my observatory

March 2015

Am currently working on a project with the AAS and producing photos for there database.

Took part in a 2 day workshop with the developer of PixInsight, the specialist software I use for my photos.

In the past 12 months the weather was very poor and I mainly spent time setting up equipment

What have I been looking at

March 2015

Now and again I got out the Dobson. Took it up 2 mountains, where the skies were great. Besides the usual, there were a couple of nice comets.

The winter was great for my favourite object, M42 The Orion Nebula.

The other week I observed the partial solar eclipse, here it was about 60% and we had lovely weather.

Aim of this website:

The aim of this site is to make public some of my astrophotographs and to pass on some of my experiances during the first few years of taking astrophotos.  It is aimed at people also beginning to work in this field and intended only to be a guide to getting to the end result faster with less problems.

A couple of photos from the recent partial eclipse of the sun, taken at the Observatory in Steinberg, Graz ( my second observatory )

A test shot using my new TS 60 f5,5 APO with a Nikon D7000 piggy backed on my Orion Telescope


The new observatory has been up and running for a while now, and has loads of space to move about in. I have spent a lot of time accurately aligning everything and i am very happy with the results. Below are some photos from the past year, those taken using narrow band filters were in the winter, I am currently set up with LRGB ( normal colour ) filters



Supernova C/2013 J - photographed on 12/02/14 and compared to an older photo. I also viewed this SN through my dobson, it was the first one I had actualy seen with my own eyes.

Sternwarte Raßberg II:

2012 was a very busy time for us, we had a total of 5 major building projects simultaneously ongoing. One of these was the building of my new observatory, Raßberg II. Due to the fact that the other projects were more important and had strict deadlines, the work on the observatory was carried out " in our spare time ".
Well, after lots of work, and a number of unforeseen setbacks, we finally finished the building in April 2013.
The new observatory is exactly as planned - it has lots of space to move about in, it is sited so that there are few problems with stray light, it is laid out so as to be efficient and easy to operate. As an astronomer I have seen a number of private observatories and I am really proud to say, that mine must be one of the best. Well, this statement is almost true - I recently was at a workshop where a collegue, who lives near Graz, told us about his new observatory. He built it in cooperation with 4 other astronomers and the astrophysics department of an american university. The observatory is at some 3000m altitude in the mountains of Chile and is remotely operated. If you wish to see what is possible, when one is at the top of the ladder, check out

New Goodies :

I have upgraded my planetarium programm to SkySafari 4 Pro, this runs on my smartphone and can control my telescope. It has a database containing some 27 million stars to mag18, 740,000 galaxies and 620,000 solar system objects including every known asteroid and comet. In addition it has maps of the moon based on the most up to date hires NASA data. I now run this on an iPad Mini - it is terrific for working with my large dobson telescope.


I recently attended a number of workshops on astrophotograhy and at one of them purchased a set of binoculars for astronomy. They are 20x80 ie realitively big and need a tripod ( from my camera ). I tried them out one evening and they are great for looking at large starfields, constellations and the like.


I also tried a number of Coma Correctors for my dobson. This is an additional lens which opticaly corrects defeects at the edge of the field of view. It was not so easy, but after trying a number of various products, I found one which worked, the Baader MPCC. The result was a much sharper and better view. I tried this out one evening and spotted dozens of galaxies.


New gear : Last year I bought a TS 60 f5.5 APO to use for widefield photography. The plan was to use it with my old Orion SSP Astro Camera piggyback on my main telescope. I did try this but was not very happy with the results. I also tried using a DSLR, my Nikon D7000 and this was much better, although setting it up to focus correctly was a nightmare. In the meantime I have considered using this setup mobile and bought an iOptron SmartEQ mount for this purpose. Basically, the mount was very good quality and had a number of really nice features but just wasn't up to the sort of photography I had planned. Even one minute exposures were out of the question. Because I have good contacts at Telescope Service, they allowed me to upgrade to a HEQ5 – this is a basic mount, but extremely stable and capable of handilng larger payloads. I haven't yet received it but I am looking forward to trying it out.
