Well, the last few nights I've been trying my hand at some basic astrophotography, with my camera attached via adapters to my telescope, turning it, in effect, into a 2000mm ƒ/10 lens. Normally this involves directly attaching the camera to the scope's tube, but tonight I decided to shoot handheld with a Takumar on my camera looking into an eyepiece on the telescope. Here is the result:
I don't think I'll continue with this method, but it was worth a try, as I have seen some very good results. This was with the 50/1.4 wide open, handheld up to the eyepiece as mentioned, and composited from about 19 frames. The field of view in the eyepiece is small, and even smaller when you try to frame it with a handheld camera. I can't tell you how many times I bumped the front element of my lens against the rubber eyecup of the telescope's eyepiece in the dark waiting for the scope's vibrations to die down so I could get a clean shot. Whoops!
Notice the characteristic warm glow of the radioactive 50/1.4 in this moon shot.
