Crab NebulaPosted By Ron Wodaski |
The clouds parted in New Mexico tonight and we got an unscheduled night of imaging with the remote telescope. I had a couple of hours before the first client was imaging, so I did a little imaging.
The seeing was especially good early on, though not bad after midnight. I managed some images of the Crab Nebula during the especially good seeing. I took nine 5-minute images and the combination of lots of exposure time and deconvolution, plus good seeing, results in a very sharp image.
I used a new technique on this image. I made two master images. I first enlarged the image 2X, and then applied deconvolution. I combined this with a second image, which was deconvolved before a 2X enlargement. The former image contributed more body (density, for those of you with film background), and the latter image contributed more texture.
The final image was 2048x24048, so I cropped the central portion and that is what is posted here. I'll add a second post with the color version. I used color from the first-light image on the remote scope.
