Takahashi Epsilon-180ED

Takahashi Epsilon-180ED Hyperbolic Newtonian Astrograph

The Epsilon-180ED looks like a standard Newtonian telescope at first glance. However, instead of the Newtonian's standard paraboloidal primary mirror, the Epsilon utilises a f/2.8 hyperboloidal mirror (F = 500 mm). A multi-element corrector lens is used at the focal plane to correct remaining aberrations from the single hyperbolic mirror. 

Astro-Physics Mach1 GTO German Equatorial Mount

This heavy duty mount has replaced my Losmandy GM-8. I'm very pleased with the Mach1. I particularly like the way the cables can be routed through the mount. Another nice feature of the mount is the very user friendly GoTo keypad. I have the Mach1 GTO mounted on a very sturdy woorden Berlebach Planet tripod (short version).

Nikon D810a DSLR

This is the special 'astronomy' edition of the Nikon D810. The DSLR is equipped with a 36.3 megapixel full frame (36 x 24 mm) Sony IMX094 CMOS sensor with a pixel pitch of 4.87 microns.

Lacerta MGEN Autoguider

Most of the DSLR deep sky images that can be found on this site have been captured and guided with a Lacerta MGEN stand-alone autoguider that also enables dithering between the sub-exposures.

Takahashi FS-60Q Doublet Fluorite Apochromat

This is a modular version of the standard FS-60C. With the extender Q the native focal length of 355 mm can be extended to 600 mm. A dedicated flattener turns the telescope into an F = 374 mm f/6.2. With the reducer C 0.72X the focal length can be reduced to F = 264 mm f/4.4. I often use this telescope in combination with a Daystar Quark Chromosphere filter for full disk Hα solar observing.

Vixen SUPER POLARIS German Equatorial Mount

The venerable Vixen SUPER POLARIS is my easy to set up travel companion for imaging or visual observing.

GreenLine Roll-off Observatory

In 2020 I built a roll-off shed observatory in my back garden. This prefab observatory is manufactured by Dome Parts GmbH. It's the medium version in their line of GreenLine R/O observatories. Click here to see photos of the construction of the observatory.

ZWO Imaging Setup

To be able to image from my light polluted back garden (SQM 18.5 magnitude/arcsec²), I acquired a ZWO ASI294MM Pro cooled monochrome CMOS camera. The camera is operated with an ASIAIR Pro equipped with an ASI120MM Mini camera plus guidescope and EAF motor focuser for automatic focusing during the imaging sequence.
