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.

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.

Lacerta MGEN Autoguider

For imaging I guide the mount and operate the camera with a Lacerta MGEN stand-alone autoguider that also enables dithering between the sub-exposures.

Vixen Guidescope 70S

This guidescope has very convenient spring-loaded adjustment screws. Unfortunately Vixen no longer produces this little refractor. 

Takahashi FC-76DS Doublet Fluorite Apochromat

A small Steinheil type of fluorite apochromat that I use for visual astronomy. Lightweight and easy to set up. The focal length is 570 mm (f/7.5). The Takahashi LE 12.5 mm, LE 7.5 mm, LE 5 mm and TOE 3.3 mm eyepieces that I use with this telescopes yield magnifications ranging from 46x to 172x. The Great Red Spot and shadow transits on Jupiter are easy to discern. Great little telescope!

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 with my Lacerta MGEN stand-alone autoguider. The SUPER POLARIS is my easy to set up travel companion for imaging or visual observing.
