Backfocus distance doesn't need to be precise, making astrophotography simpler with filter drawers, OAGs, and other accessories.  The 111F's 766mm focal length gives you a 2.7° field of view on the long side of your full-frame imager, 1.8° with APS-C cameras, and 1.0° with a 1\" (2.7x crop factor) camera.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1979\/5379\/files\/FOV_118e613b-ba9c-4f42-9030-97698e47b7e4.jpg?v=1778806384\"\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eFields of view with full-frame, APS-C, and 1\" (2.7x crop \u003c\/strong\u003e\u003cb\u003efactor) cameras\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eUnlike many contemporary refractors, this one can be used for visual observations, as well.
