The Alpine Astronomical Baader 76° Morpheus 17.5mm Eyepiece is designed to deliver the performance that avid amateur astronomers and astrophotographers require for near and deep sky use. Outfitted with a wide 76° field of view, it presents an immersive observational experience while ensuring slow-moving deep sky objects remain in the eyepiece view for a long time when observing through non-motorized telescopes like conventional Dobsonians.





A combination of flat-field lens design, lens coatings, and internal baffling and blackening ensure bright and clear views with limited distortion across the entire field of view, especially at the edges. To further improve the viewing experience, the standard round fold-down eyecup can be removed and replaced with the provided winged eyecup to eliminate peripheral light and improve contrast and resolution.





Integrated 1.25" and 2" barrels make this eyepiece compatible with the two most common holders, drawtubes, and accessories, without having to switch sleeves when moving from one optical tube assembly (OTA) or set of accessories to another. For ease of use, all the Morpheus eyepieces are parfocal with each other so there is little to no need to refocus when changing eyepieces within the series. To help you find the right eyepiece without needing a flashlight, the focal length is engraved on the housing and colored with photoluminescent paint that glows a faint green. Additionally, a stainless steel clip is included that attaches to the eyepiece holster and lets you bend up one or more small tabs to quickly identify an eyepiece by touch. All these features eliminate the need for a flashlight, which can affect night-adjusted vision and prevent you from seeing dim objects.





Useful for more than just visual observation, the eyepiece has 43mm T-mount threads under the eyecup that accept camera-specific T-rings for direct connection of CCD imaging systems. A 43mm extension ring is provided that can be attached to the integrated threads for the T-ring and provide more back focus if the camera requires it.
