I bought this OTA from Bresser, I must say I was impressed at the quality and built of this beautiful telescope. While I haven't been able to point it into the sky and actually check it's optical clarity and performance during the night time, I managed to do so in the day observation of nature, fantastic clarity and performance. This is a huge telescope and require a steady, stable mount. That's why I also bought Bresser EXOS-2 mount. Unfortunately the guys here sent me a mount with a major flaw, I am waiting to see how they can help out to fix it.
Usually telescopes are sold with poor quality diagonal mirror and only one eyepiece. The diagonal mirror of this scope is of high quality, although the body seems to be made out of plastic. However, it contains a thick, coated, high quality mirror. The eyepiece is a 26mm, really high quality, but of course it is not enough to bring out the real power of this scope. All in all, it's an amazing scope with an amazing design.
