The Meade 07378 T-Mount SLR Camera Adapter attaches your telescope to your Nikon SLR or SDLR camera with the help of any T-threaded camera adapter (sold separately). The Nikon T-Mount allows you to attach your camera to the Meade telescope and camera adapter of your choice. Ultra Telephoto photography is made easy with this item, but be sure to lock up the mirror and use a cable release or remote to fire the shutter to minimize overall vibrations. The focus mode switch on your camera must be on "manual focusing." The Meade 07378 T-Mount SLR Camera Adapter comes with a 1-year limited warranty. Meade has everything you need to capture the night sky for experienced star-shooters, serious researchers and beginners alike. Serious astronomers for years have flocked to Meade telescopes for their quality optical systems and patented technology. Consumers know that "Meade Optics Inside" means that what they see through our telescopes will be views that are detailed, crisp and full of contrast. Look through a Meade this evening and see what you've been missing.
