| M3 Globular Cluster |
|
| 2002-04-16 21:22 to 21:35h hUT Central portion of Mosaic CCD Image, 30 sec exposure Portion area 12.2 x 9.4 arc min (#21020-36) (Contrast set in order to show full extent of the cluster, but in the process the centre of the cluster is 'washed out') |
| M3 mosaic |
|
| 2002-04-16 21:22 to 21:35h hUT Mosaic CCD Image, 30 sec exposure (4 x 4) 36.2 x 20.0 arc min (#21020-36) (Mosaic construction method) |
| M3 composite |
|
| 2002-04-16 21:19h hUT CCD Image, 30 sec exposure 9.1 x 7.6 arc min (#21016) Composite image showing view with two different contrast settings (Left hand contrast setting shows full extent of the cluster, but at the expense of loosing detail in the centre which is 'washed out') |
| M3 |
|
| 2002-04-16 21:19hUT CCD Image, 30 sec exposure 11.4 x 7.6 arc min (#21016) |
| M3 detail (square root brightness scaling) |
|
| 2002-04-16 21:52h hUT CCD Image, 60 sec exposure 5.1 x 3.4 arc min (#21041) Taken with Barlow and using square root brightness scaling to show maximum detail |
| M3 (linear brightness scaling) |
|
| 2002-04-16 21:52h hUT CCD Image, 60 sec exposure 5.1 x 3.4 arc min (#21041) As above image but with linear brightness scaling |
