Solar observation with Merz 75mm from 1890


Observed the Sun the Merz 75mm refractor, equatorial mounted.
This telescope dates from the 1890's.
Used the original Merz eyepieces. Simple Huygens eyepieces but from very good quality.
Nice sharp and contrast views. Lot's of details in the sun spots.


This is an impressive 19th century German telescope.  Used this telescope several times and I'm impressed with the optics and the mechanics of the equatorial mount.

Georg Merz d. 12 January 1867, left business to sons Sigmund & Ludwig.  S. Merz

Harris & Son Newton telescope

Finally the Harris & Son Newton telescope arrived from the UK. Thomas Harris was active in London between 1780 and 1817. The telescope and the mount in bad condition. Lot's of original parts are missing. When I bought the scope the mirror was perfect. When it arrived is broken. Big loss. But it's a historical interesting instruments who deserves to be restored. It will take a lot of time. No hurry. Still have enough other telescopes who need my attention

Secretan, box with 7 telescope eyepieces 1950's

Secretan was one of the finest opticians of France.  This a rare box with 6 astronomical and 1 terrestrial eyepiece.

The astronomical eyepices can be used in combination with modern telescopes.

Tested the eyepeices with a modern refractor and they perform exceptionally.  I suppose this are orthoscopic eyepieces.

Very rare to find these separately.

Secretan 8cm telescope +/- 1920

This is a complete 81mm Secretan refractor.  The alt az has slow motion control on the two axes.  This is rather uncommon. 
The slow motions are working very smooth.  Hard to find a Secretan 81mm with the complete alt az mount.
In the 1930 telescope catalogue it is mentioned as a additional option.

The Secretan telescope is in very fine condition.  It has completely cleaned, re-lubed and restored.
The views are excellent as you can expect from a Secretan refractor.

Photo of M27 made with the 1000mm Zeiss Spiegelobjektiv

During my last visit in the Provence for theATOS-project I visited my good friends Caroline and Jean-Luc Plouvier from the Domaine de la Blaque in Varages.  You should visit them.  It's paradise.

Was able to use Jean-Luc's Mesu 200 mount to make some astrophotos with the Zeiss Jena 1000mm f5.6 Spiegelobjektiv.
