This video shows which type of connectors are great for connecting a Nikon DSLR to a reflector or refractor telescope. The connectors allow you to achieve prime focus without the need to use an eyepiece, as in eyepiece projection. A thin T ring piece is needed that is no more than 9 to 11 mm thick, so as to get the lense of the camera as close as possible to the secondary mirror of a reflector or Dobsonion telescope. A 16.5 or 21 mm two inch wide threaded spacer is then screwed on to the T piece, to attach the camera to the telescopes focuser. Focus is usually achieved very close to the secondary mirror.For those who try this method and still can't achieve focus, then a 2 inch Barlow can be directly attached to the dslr via the spacer. Barlows come in one and a quarter and two inch sizes, so a 2 inch model would be required and would be superior at gathering light anyhow. The model of the T ring is shown on the video. They can be found for purchase by Google searching the name and numbers on the unit shown.The spacers can also be purchased from Orion, but its best to buy a set in case you need to extend your camera further out. I would recommend two 21 mm, one 16.5 and a 5mm. I purchase mine from the Zwo imaging online store.Please note that all of the images shown were taken on prime focus,but some of them were cropped to give a closer look at the lunar surface.
