• Mesumount 200

This is my main mount and permanently set up in my observatory. Reasons for picking this friction-drive mount is its high tracking accuracy with a very small periodic error (<3 arcsec peak to peak). This is very convenient for photography purposes. Next to that I was able to purchase this mount at the introduction price which makes it an excellent value for money. More info here.


  • Vixen GPD

This is my ‘grab and go’ mount. Not that easy to grab but is has gone to a lot of places.



  • Astrosib 10″ f/8 Ritchey – Chrétien Astrograph

This narrow field telescope is used for deep sky photography purposes only. It delivers a nice flat field over a large area. This model has an exceptionally large image circle of 80mm diameter. Astrosib telescopes are renowned for their excellent optics. More info here.

  • Takahashi FSQ106ED

The Tak is my main imaging refractor. I recently upgraded it with a Robofocus motorized focuser. More info here.


  • Celestron C9.25 f/10 Schmidt Cassegrain

The C9.25 was my main planetary and lunar telescope for quite some years. I upgraded it with a Moonlite focuser. Since I acquired the C14 I don’t use it that often anymore. But I still keep it for when seeing conditions are not that good. More info here.


  • Celestron C14 f/11 Schmidt Cassegrain

The second hand C14 is my main planetary and lunar telescope since 2014. More info here.


  • William Optics Zenith Star 66mm Petzval ED

A nice little refractor which I used to have as a guiding scope. Now I use it occasionally for widefield stargazing.



  • QHY9 (Alccd9)

My deep sky imaging camera, the QHY9 – KAF8300 monochrome CCD, 2-stage peltier cooled and with an automated filter wheel. More info here.


  • Imaging Source DMK21AU(618) and DMK41AU02

These funny blue blocks are my planetary, lunar and solar cameras. The DMK21 used to be the standard AU04 version but I upgraded it with the much more sensitive icx618ala chip. The DMK41 has a larger CCD and is mainly used for making mosaics.



  • Solarmax 60mm Ha filter

My solarmax filter is a pre-Meade model. It is solely used for solar H-alpha viewing. It has a passing bandwidth of 0.7 Ångstrom and thus blocks the sunlight for about 99.99%. It comes with the BF10 blocking filter.
