Bresser telescope Messier MC-100/1400 OTA

True in focus focal length is closer to 1850 and the baffle tube causes vignetting with a 40mm Celestron Plossl, as is visible on the evening moon photograph, so it doesn't even show a full 1.25" fov.I have also discovered a problem with the construction, that plastic moulding at the rear of the 'scope hides some pretty poor design decisions...if you take it off you will discover that the eyepiece holder (with it's poorly positioned thumbscrew that doesn't line up with the safety grooves on better quality parts) is not attached to the focuser tube! There's a perfectly usable thread on the end of that tube but instead the poor quality (very shiny inside and that thumbscrew issue!) eyepiece holder is held by a retainer on the inside and "floats" roughly around the right area. I've stripped mine off, using tube rings to mount and luckily I don't need the finderscope mount with my Rigel.However the thread that's exposed is fussy about what will screw on there, I've managed to fit an eyepiece holder but I'm not happy with the original design compromises. Now with a solid attached eyepiece holder I can properly enjoy the views but had I known about this I might not have bought the telescope.I have managed to find some DSOs with it but it's limited to the widest eyepieces because the true magnification is so much higher than the specifications suggest even after I shortened the optical path.Unfortunately not recommended.
