Comments on: In film SLR astrophotography is the image projected from the eyepiece directly to the film? http://www.astronomag.com/astrophotography/in-film-slr-astrophotography-is-the-image-projected-from-the-eyepiece-directly-to-the-film Sat, 31 Jul 2010 23:27:59 -0500 http://wordpress.org/?v=2.8.4 hourly 1 By: injanier http://www.astronomag.com/astrophotography/in-film-slr-astrophotography-is-the-image-projected-from-the-eyepiece-directly-to-the-film/comment-page-1#comment-5410 injanier Fri, 05 Feb 2010 09:53:59 +0000 http://www.astronomag.com/astrophotography/in-film-slr-astrophotography-is-the-image-projected-from-the-eyepiece-directly-to-the-film#comment-5410 Most often, the camera is mounted to the telescope directly, using the scope as a telephoto lens. You can also do afocal (camera lens to eyepiece) and eyepiece projection ( using the eyepiece to project a more magnified image onto the film). Any basic book on astrophotography will describe the specifics. Desirable characteristics for the camera include mechanically operated shutter (so it doesn't run the battery down keeping the shutter open), mirror lockup, and interchangeable focus screens. The Olympus OM1 in 35mm and the Pentax 6x7 in medium format have been very popular.<br><b>References : </b><br> Most often, the camera is mounted to the telescope directly, using the scope as a telephoto lens.

My setup cost me about $50 and I can use any of my Nikon 35 mm SLR's or DSLR's. I now use a D300 using the "live view" mode to fine tune the shot before taking it. You will need a motor driven telescope to track the subject of your nights shooting to correct for the earth's movement and rotation during the long exposures necessary to capture all celestial objects but the moon.<br><b>References : </b><br>proFotog Any camera can be adapted to the eyepiece of an amateur telescope using a T-mount adapter and suitable T-mount to eyepiece adapter.
