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.

Takahashi FC-76DS Doublet Fluorite Apochromat

A small Steinheil type of fluorite apochromat that I mostly use for visual astronomy and solar imaging. Lightweight and easy to set up. The focal length is 570 mm (f/7.5). The Great Red Spot and shadow transits on Jupiter are easy to discern. Great little telescope!

INTES MK-67 Maksutov-Cassegrain

Already owned one in the past and reacquired one in 2020. These no longer manufactured 150 mm f/12 (F = 1800 mm) Rumak design Maksutov-Cassegrains are excellent for visual astronomy, and therefore also known as 'apo killers'.

Vixen SUPER POLARIS German Equatorial Mount

The venerable Vixen SUPER POLARIS (SP) is my grab-and-go mount. Equipped with a DD-3 Dual Axis Controller I can guide the mount if desired. The 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/arcsecĀ²), 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. 

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.
