The focal length is 45.5mm, the magnifications given are correct for the Baader Classic eyepieces and all other eyepieces where the field sop is 2mm inside of the 1.25" nose piece. The magnification factor of a Barlow lens depends on how far it is from the field stop of the eyepiece or the camera sensor. So if your camera is in the wrong distance, it will deliver a different magnification. We have now explained this more extensive in this FAQ.

The inside is black and with ripples against reflections, and we haven't seen reflections or had complaints about reflections.

We have just tested this combination to be sure.

The 2"-barrel of the Morpheus eyepiece can be fully inserted without any interference.

We have no idea why Meade changed their thread norm just a tiny bid when they copied Celestrons 3" thread. Celestron was first - but that had happened more than 40 years ago..

Also about 35 years ago we started to do accessories with that 3.3" size - and we saw that if we do create our own norm for the thread width - which is a tiny bit wider on the Celestron OTAs, then we could do one ring that will fit both telescope brands.

So we do produce 3.3" threaded rings with our own "in-house-standard" - and it works on both brands.

Thank you very much for your very nice feedback! If you have some photos of the equipment and astrophotos that you took with the equipment - and you would allow us to publish it in our product page blog together with your feedback - please send it to support@baader-planetarium.de
