Tele Vue Nikon F Wide T-Adapter w/Bayonet for 2.4"

 Nikon cameras are popular with astro-imaging enthusiasts. But, the typical T-ring / telescope setup does not take advantage of the wide aperture of the bayonet mount: significant vignetting is caused by the constriction of the T-ring opening. Nikon F Wide T Adapter with Bayonet for 2.4" connects to your Nikon F-mount camera in place of the T-ring and provides 13% greater aperture to minimize vignetting. Can be used with Nikon Z-series mirrorless cameras using an F-to-Z adapter (FTZ) available at camera stores.
