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.
