1,25" Galilean Eyepiece
thingiverse
The initial use of eyepieces involved the utilization of a simple concave lens, which offered the advantage of producing non-mirrored or upside-down images. However, these eyepieces had a relatively smaller field of view compared to the subsequently invented Keplerian eyepieces. This eyepiece is designed for a concave lens with the following setup: Diameter: 25.4 mm Focal length: -25 mm Leave a comment and I can generate setups for other specification of a concave lens. ## The poor mans telescope This eyepiece is generated from the following poor mans telescope project. You can download the FreeCAD files for the eyepiece from the github page. [Github - 3d printable telescope](https://github.com/leonardsaers/3d-printable-telescope)
