Mounts
- 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.
Telescopes
- 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.
Cameras
- 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.
Filters
- 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.
- Color filters 2″ R, G, B and L from QHY
- Narrowband filters from Astronomik
- H-alpha 6nm 2″
- O3 12nm 2″

Bart,
Als je met de 16″ f3.75 Dream Scope werkt, gebruik je dan een OAG om te guiden?
Ik werk unguided, met dank aan de ASA montering. De lights zijn meestal 300s, lang genoeg voor dit snel systeem.
