NGC 3242 "Ghost of Jupiter" Nebula | |
At magnitude 8.6, NGC 3242 is a bright planetary nebula, but is still very much dimmer than it's namesake. It is about 1/2 the size. Still it's is bright enough to be seen in a small scope, and if you have dark skies you just might be able to glimpse it in 10x50 binoculars as a slightly extended star. You should be able to see it as round bluish-green glow in a six or eight inch scope at 75-100 power.. For a size comparison, compare this image to the f10 images for M-57. The image scale is about the same. | |

This image was taken at the same time as the f10 image below. The Orion MAK 500 was attached to the LX 200 which was guided by MX-5C and STAR 2000. A nice feature of my system is that I can image through both the Orion MAK 500 and the LX 200 simultaneously. Click here for a larger image. |
