Here's a couple of shots I took of the Moon with my D40 a couple of years ago. Sadly it had to go but I've got a new camera now (D5100) and hope to start collecting more photons. Sorry but exact exposure details are on an old computer that needs winding up before it'll start.
Nikon D40, OMC 140 'scope with x0.63 reducer (1250mm, f9) ISO 200. Had to play with the sky a bit due to vignetting caused by the reducer.
Same set up as above but one exposure for the Earthshine and one for the limb. Seemed simple enough at the time but the terminator needed LOTS of "cosmetic" work to look as it did to the eye.
Mosaic of the Moon
Nikon D40, OMC 140 with x2 Barlow (4000mm, f28) ISO 200, I think the exposure was about 1/15 sec. Took about 100 shots and stitched the best bits together and re-sized. I'm hoping the D5100 is less noisy so I can increase the ISO and shutter speed to counteract atmospheric seeing, the D40 was quite noisy above 800 ISO but the faster shutter would show more (grainy) detail.
x1 crops from the finished mosaic, they look a bit blurred to me now but printed up it looks OK, the bigger the print the further you stand away?
