Andromeda M31 - Take two
Last year I took my first successful photo of the Andromeda galaxy. And yesterday I improved a lot in my second try. This time M110, M32, Nu Andromedae and 32 Andromedae are all clearly visible.
Technical details
The image is taken with a 300mm ƒ/4 lens on a regular tripod. Here’s the setup:
| Focal length | 300mm |
| Aperture | ƒ/4 |
| ISO | 8000 |
| Exposure time for light frames | 699 * 1/2s |
| Dark frames | 50 |
| Flat frames | 50 |
| Bias frames | 50 |
The raw photos were stacked and then post-processed in Siril. First used Photometric Color Calibration to get color correction, then auto stretching with manual tweaking. After that some background extraction, and finally some last tweaks in Lightroom.
