Image 1: The plate on the telescope
This shading plate is an optional tool for improving your viewing experience through a telescope. It significantly increases the contrast of details in the FOV, since it blocks scattered light coming from the front side. This thing really works! Unlike similar plates found in the market, this plate is NOT simply held by friction between both 2" ends. It is screwed on a special tailor-made 2"<->2" inches adapter, which is part of the system! The plate is slightly bent at the side of the observator to provide enough space for him. ->
Hence, it is not just a simple "plate", but a complete mechanical shading system. It is robustly built and tailor-made by AstroHolgiShop (http://www.astroholgi.de).
A Baader diagonal mirror is used, since if offers a SC (Schmidt-Cassegrain) thread at the telescope side, making it suitable for screwing a shorter tailor-made adapter to 2" since the used Dall Kirkham telescope had a very limited backfocus.
