Overview
The Baader Morpheus 9mm is a well-regarded mid-to-high magnification eyepiece that works across a wide range of telescopes and observing targets. Its 76-degree apparent field of view gives you a genuinely expansive view of the sky, making star clusters feel three-dimensional and giving nebulae room to breathe. At 9mm focal length, your actual magnification depends on your telescope's focal length, so check that pairing carefully before buying.
The 21mm eye relief is a real practical advantage, especially for eyeglass wearers who often struggle with shorter relief eyepieces. The 8-element, 5-group optical design keeps distortion and coma well controlled across the full field, which matters when you are comparing stars near the edge against those at center. Build quality is solid, with a sealed housing that holds up in the field and a rubber grip that stays manageable in cold weather.
It fits both 1.25-inch and 2-inch focusers without adapters, and it is threaded for standard filters. At around $387, this is a premium purchase, but the optical and mechanical quality justify the investment for observers who use their equipment regularly.

I bought the 17.5mm Baader Planetarium Morpheus to replace a 17mm Televue Nagler Series 4 that was lost in a move of my household. Prior to this, I purchased a set of Meade and Orion Plossls and, later, a set of Baader Plateriam Hyperions, so I can compare the Morpheus with a 18mm Meade 4000 series ...
Eyepiece provides awesome view of objects. Long eye-relief is great. excellent mid-range magnification with a good price range. Comes with everything one might need for either viewing or projection astro-photography.
I installed this lens in my Kowa 883 sporrting scope using the astro-adapter from Kowa. This gave me a magnification of about 125X. Looking at the landscape of the full Moon is breathtaking. I also used it to get a final glimpse of the recent comet. Using it on land is iffy because of atmospheric co...
