NGC 891
From time to time I obtain data sets from remote observatories. One of my favorite providers is the Insight Observatory with telescopes in e.g. Chile, Namibia, New Mexico etc. One of the data sets I received, was data from the galaxy NGC891, located in the constellation Andromeda.
The images were taken with the following equipment:
| Location | Lijiang, China |
| Telescope | AG 10 CDK |
| Focal length [mm] | 1655 |
| Focal ratio | 7 |
| Mount | Skywatcher EQ8 |
| Camera | FLI Proline 6303 |
| Filter | L:R:G:B |
| Exposure time [min] | 310:120:90:110 |
| Resolution | 1.12″/px |
Data calibration and registration and the final processing was done with PixInsight. The result was as follows:
The faintest star in this image has an apparent magnitude of approx. 21.5 magV (PPMXL).
