| Distance: 2.54 million ly |
| App. Magnitude: 3.4 |
| App. Dimensions: 190'x60' (cf. telescope field of view 119') |
Notes: The detail in the disk seems good, but we know from looking at images taken by others that the disk has a larger diameter. The core is overexposed. Our polar alignment and pre-processing skills are primitive. More of the disk can be seen in image (4), and more detail in general can be seen in (5). Zoom in/out with ⌘↑(+/-) (Mac), ctrl (+/-) (PC). |
