I end this review by confirming that the Oberwerk BT-100-XL-ED is a quality product, it has optics that rival the best competition – even more expensive ones, it is compact, lightweight and is perfectly suited to terrestrial observations as well as astronomical ones. I am very curious to try the 82 mm diameter version, to compare it to my Kowa Highlander Prominar.
