The Globular Cluster NGC 6205 (M13)
| Scope: | Altair 250mm RC f/5.3 |
| Camera: | ZWO ASI 183MM Pro |
| Mount: | iOptron CEM120EC |
| Filters: | None |
| Exposure: | 30 x 120sec subs, Flat fielded and dark subtracted |
| Processing: | There was no background gradient at all, so all that been done on this is to reduce the background noise using Russell Cromans excent Noise Exterminator plug-in for PI and into Affinity to back off the core a little. |
