The best scope is not necessarily the one with the biggest or most expensive optics – it’s the one you use most often. I had to learn to take the “bigger is better” rule of thumb with a large grain of salt. My big scope has trouble with light pollution in my backyard, and “oh, boy”,  I am often to lazy to haul out my 25 kilo equipment  for a few hours.

  • MakAndCameraNewton: As a deep space observer, I got with the ORION UK (203 mm f/6) the biggest size taking in mind weight and light pollution but it is already so big and heavy that I need (mental) strength to move mount and telescope. It is a well-built British made telescope though, designed for Galaxies, Nebulas and indeed allows good views of planets (and of course the moons).
  • TMB800600f6bMaksutov: My medium size long focal ratio reflector, Maksutov-Cassegrain INTES 603 (150 mm f/10),  will often used  with a reducer. The scope looks and feels quite heavy. A dovetail rail is attached to the underside of the scope fits directly to the mount. The finderscope bracket and camera piggy back bracket can both be left on and still fit inside the case. The finderscope adjustment screws have nylon tips to prevent them from damaging the finderscope.
  •  APO: My  small size refractor TMB 80 (80 mm f/7.5)  The Fluorite Triplet Apochromat is regarded as the finest small aperture glass available, is smaller/lighter (APM version), and very well established optic using FPL-53 ED glass. It has a ”dual-speed FeatherTouch” focuser and a retractable dew shield, dust covers.
  • Binocular: If my main interest is just cruising star fields or if I use my  Fujinon 10×50 FMTR-SX as a spotter for one of my telescopes. My hands down favorite binocular astronomy view is what I see while lying down in my lounge during the summer and looking a little eastward of the zenith soaking in the star rich area around Cygnus/Aquila through my Fujinon 10×50’s.

My equipment - rather small

My equipment – rather small

The current mounts I use, are an AZ-HEQ6 and one HEQ5 mount. Both are controlled over WLAN. I am using a SkyFi box for the AZ-HEQ6. SkyFi  create its own Ad Hoc Wi-Fi network or works in Info mode. The SkySafari app on a Nexus uses the SkyFi name to auto-detect your SkyFi when it has joined an existing Wi-Fi network. To secure the network,  a WEP or WPA2 key will be used. Read more here.


Sky-Watcher AZ-EQ6 SynScan

mountThe main mount Sky-Watcher AZ-EQ6 SynScan gives good heavy-duty stability and pointing accuracy. It is a hybrid mount with alt-azimuth capability for general use, and equatorial capability for astrophotography use. Supplied with a SynScan handset with dual AZ/EQ firmware, it can automatically find and track 42,900+ celestial objects from its database.

This is a still transportable mount for the field weighing only 15 kg, for a load capacity of 20 kg (counterweight excluded). It has a dual-encoder technology which allows the telescope to be moved manually or electronically in either axis without losing its alignment or positional information. After moving to a new object the telescope will automatically begin to track the new object accurately. No re-setup is required in one observing session.

  • German Equatorial / Alt-Az dual mode
  • Permanent periodic error correction(PPEC). PPEC can be trained with Autoguider or PC.
  • Low backlash, silent slewing.
  • Includes two dual-fit (45mm/75mm) saddle for mounting two telescopes.
  • Polar-alignment with polar-scope.
  • DSLR Electronic Shutter Release Port , Autoguider Port
  • Alignment methods: 1, 2, or 3 star alignment (EQ) / brightest star or 2 star alignment (AZ)
  • 2 x dual-fit saddle plates supplied accepting 45mm & 75mm dovetail bars RA/DEC Worm Gears: D=92.5mm, 180 teeth, brass RA/DEC Axes: D=40mm, steel


HEQ5SynTrekZMy auxillary HEQ5 mount is fixed in the office. It is a good sturdy mount, good for 12 kg, with both axis motorized. The HEQ5 Standard from Syntia, with its original slow but good DC drive motors is OK for basic tracking I upgraded it with the SynScan GoTo upgrade kit for HEQ5 mounts. The GoTo Upgrade Kit installs more precise stepper motors and adds the Synscan hand controller for better alignment, tracking and location of objects.



Besides a fast GoTo system and a  connection to the computer using the Ascom Celestron Unified (5.0.30) driver,  it has an auto guide port which I have connected via a STAR2000 XPRESS Starlight system and an old fine MX716. The  HEQ5 mount is wireless originally via blue tooth and recently self integrated wireless using an USB hub. It’s a Silex USB device server with isochronous data transfer, and USB2Serial Converter. Only power cables go to the mount to the mount.

Manfrotto 055CXPRO4 Carbon Stativ Pro is a reasonable semi-professional tripod specifically designed for extreme outdoor assignments. The legs and the column are made of 100% carbon fiber combined with magnesium die-casting quick action lever locking collars. Each leg can be independently set at four different angle positions. This professional tripod provides great rigidity and lightness, combined with the best professional features such as the patented Q90° center column system. The magnesium top plate integrates a leveling bubble. I use it with an  Pro Digital Geared Head Rapid Connect Plate. The 410 Pro Digital Geared Head was good specifically to meet the more exacting, time-sensitive needs of astronomy photographers with payloads up to 7.5 Kg. It utilizes large, easy-to-grip knobs that provide smooth, positive, geared control through 360° pan and +90° -30° frontal and lateral tilt and features instantly disengagement of gears and rough position the camera by hand, then instantly re-engage them for ultra-precise final alignment. I use it when I go backpacking and weight matter just with camera and a a simple nano-tracker and a 50mm an 15 mm lens.  In addition I have a Berlebach wooden tripod, which is my favorite (but usually stays in my photo-studio.

My Astro-5 German equatorial mount is one of the better Chinese-made EQ5s out there, if this sample is indicative of the batch. Both the declination and right ascension worm drives must be nicely adjusted. The built-in illuminated polar alignment ‘scope is a nice touch. This mount is quite capable of supporting my Newtonian around 8-inches, certainly my conventional achromatic refractor, and my 6-inches  INTES 603 Maksutov-Cassegrain (though the extensible two-piece aluminum tripod will be a bit low).

Communication and Goto

The Skymaster mount is controlled by Tablet (Kindle or my Nexus 5 smartphone) with Skysafari or my Laptops with Ciel 3.8 using Skyfi, over WLAN. The other two mounts use a self-built Littlefoot — basically a poor mans GoTo.
Given there are so many EQ5s out there it was only a matter of time before versatile GoTo upgrade kits would come to fit them all. The Littlefoot includes a rather funky-looking hand controller 12V servo motors for the declination and polar axes, power supply, mounting hardware, cables (including RS232 serial lead. Communication is over serial to USB converter and a Silix printer server to run it over WLAN. Sadly, the Littlefoot will be not supported anymore, by its inventor.

When it comes to alignment of the Littlefoot, you have only one star which assumes that you have a good polar alignment.  All told, the pointing accuracy of the Astro-5 combination for stellar and deep-sky objects was pretty good (<0.5° error for targets less than 60° from an alignment object). The pointing accuracy can be significantly improved by ‘syncing’ to a nearby star, then performing a short Go To hop from there. The Sky-Scan is of course in a different league.
