The eclipse 2015, but then moved me to buy related accessories in order to make photos. I put a Sony SLT Alpha 65 a on a Skywatcher 70/900 refractor. This part is actually it not absolutely necessary, but the ability to set the camera directly to an eyepiece to use its magnification, then have been too tempting. I bought for my nightly excursions over time some Baader Hyperion_Okulare, for these parts are made.
Also schwar again anodized metal components. The quality is adequate. Unfortunately, the number of threads is very low. While it holds everything, but does not really get the impression that it is made for frequent use. I also still have a Baader Planetarium Hyperion Zoom eyepiece. Unfortunately, these parts do not fit precisely there. At the fixed focal length but everything fits easily.
