As we still have a few nice items left from the heritage of Alex Nieuwlandt, I will be bringing them to the ATT-messe this year (Saturday, 9th of May)
Teleskop-Service 150mm triplet ED APO f=1.000mm (f/6.7) SOLD!!
Last known value (new): 6.800 € ?Value second hand: 4.000 € ?


127mm f/12 D&G refractor
A beautifully finished classical (i.e. “very long” :-)) refractor – resulting in high-quality images at an affordable price (but you will need a slightly more robust and higher mount – compared to the modern shorter ED and triplet refractors).
Comes with a Lichtenknecker Optics (“LO”) style dovetail, but that can easily be changed to a Vixen of Losmandy-style.
- Last known value of comparable instruments (new): 800 € ?
- Value second hand: 300 € ?


152mm f/5 O.G.F. refractor
A very nice short refractor (AKA “a Comet Catcher”) for those who enjoy extra wide vistas of the sky. Build around a 6 inch d/5 (f=762mm) lense from O.G.F. (Optical Glass Fabrication – I didn’t knwo the company neither :-)).
Comes equiped with a superfine helical focuser from Lichtenknecker Optics (LO) – but don’t worry: an adapter (System64 to 2 inch) is included! Has enough backfocus to accomodate most bino-viewers!
The scope sits in the well-known “pirate chest” box from Celestron, and comes with 2 sturdy aluminium tube-rings.
- Last known value of comparable instruments (new): 1.000 € ?
- Value second hand: 400 € ?



AstroPhysics 600E Servo
Comes with a 2nd (spare) SMD controller (probably the first generation of AP controllers??). Doesn’t have GoTo yet, and we’re not 100% sure if it can be equiped with the more recent GTO-controllers from Astrophysics (if not, OnStep might be a solution!!). But the mechanical quality stands without any doubt!!
This is your chance to buy a hi-quality mount at a bargain price!
No tripod, but an adapter is included to mount it – for example on Berlebach tripods. But does come with a few counterweights…
- Last known value (new): ??? €
- Value second hand: 3.000 €

Vixen Saturn (manual)
The beefiest of the 3 Vixen-mounts – could probably carry a 20 kg telescope and more (30 kg?) – such as the Celestron C14. Was used as a manual mount, but the original RA-motor (synchronous motor?) and electronics are available – and even a more recent stepper-motor from Vixen (but not sure about the handset for this one…).
Stands on the original heavy mobile pier.
Last known value (new): ??? €
Value second hand: 750€ ?

Lichtenknecker Optics (LO)
For those who (rightly so!) still love and use the beautifull optics and mechanics from Dieter Lichtenknecker and his successor…

Diagonals / finderscopes / filters / tube-rings / …
And indeed lots and lots of smaller stuff…
