Takahashi Epsilon-180ED on Astro-Physics Mach1 GTO and Berlebach Planet tripod (short version)

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. This produces a large, flat field at a very fast f-ratio.

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 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. For imaging I operate the camera with a Lacerta MGEN (V2) stand-alone autoguider that also enables dithering between the sub-exposures.

INTES MK-69 Maksutov-Cassegrain

This rather rare 150 mm f/6 Sigler Maksutov-Cassegrain (F = 900 mm) is specially designed for astrophotography and therefore often called the PhotoMak. The large secondary mirror (placed halfway the tube in a four-vaned spider) creates an obstruction of 50%, which means relatively poor contrast for visual use. The MK-69 was my answer in the quest for a reasonably fast telescope with a focal length of about 1 meter.

Vixen SUPER POLARIS German Equatorial Mount

The Vixen SUPER POLARIS (SP) is a venerable light-weight mount. Equipped with a DD-3 Dual Axis Controller I can guide the mount with my Lacerta MGEN stand-alone autoguider. The SUPER POLARIS is my easy to set up travel companion for imaging or visual observing.
