telescope (26)

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.

Meopta 5,5cm table top telescope, school telescope

School telescopes were a tradition in Germany in the 1920's.  In Eastern-Europe several telescope makers continued to make them after the 1950's.

Meopta is still known for excellent optics.  Tested the school telescope and the optics are sharp and very good contrast. 

The mount is very solid.
