Polarizer & Neutral Density

The optical lightway can be found under the Tab "Specifications". It is adjustable from 32 - 38 mm.

You probably need to adjust the two brass pins on which the mirror rests in its lower position. This way, you can move the image along the optical axis of the telescope (either closer to the telescope or to the camera).

To test this, take a look through the eyepiece and move the mirror slightly up - if the star moves in the desired direction (or contrary to it), then you need to adjust the brass pins. Please see page 11 in the manual (chapter 3 - Adjusting the mirror). If it moves sideways instead, things get complicated. But that's most probably the solution.

Please ask your dealer were you bought the eyepieces or the distributor in your country. You can find dealers and distributors with our store locator: https://www.baader-planetarium.com/en/storelocator

In its downward position, the mirror has got a length of ca. 2,5cm, so there are only 2-3mm for an autoguider prism. This might just work, but we wouldn't recommend (and be at peace with ourselfes).
To be honest, autoguiding is usually used for larger sensors which would be obstructed by a 1,25"-focuser anyway, and most focusers which are strong enough for a flip mirror, a camera, a guiding camera and maybe even an eyepiece are 2"-focusers, so we preferred a larger mirror.

The MPCC is an tool for Deep Sky photography with Newtonian telescopes. It not designed for use with an Barlow lens that you normally use for high power photos or visual observations mainly of Solar System objects. The barlow lens would magnify the middle of the field wich is mostly coma free anyway. We suggest to work with the Hyperion Zoom and Barlow lens and without MPCC.
