Sharpless 2-199
The Heart Nebula, NGC 896/IC 1805/Sharpless 2-190, and the Soul Nebula, Sharpless 2-1999, combined, are one of the best wide-fields the sky has to offer. With my 115mm refractor, it’s way too wide to get in a single panel. This is a nine panel mosaic, captured over two nights.
The largest mosaic I’ve tried before this was two and three panels, all the same night. So, this is a lot more ambitious. But I’m exceptionally pleased with how this turned out.
| Panel | Exposure | Gain | Offset | Frames | Integration time |
|---|---|---|---|---|---|
| 1 | 60s | 56 | 25 | 60 | 1h |
| 2 | 60s | 56 | 25 | 60 | 1h |
| 3 | 60s | 56 | 25 | 60 | 1h |
| 4 | 60s | 56 | 25 | 60 | 1h |
| 5 | 60s | 56 | 25 | 60 | 1h |
| 6 | 60s | 56 | 25 | 60 | 1h |
| 7 | 60s | 56 | 25 | 60 | 1h |
| 8 | 60s | 56 | 25 | 60 | 1h |
| 9 | 60s | 56 | 25 | 60 | 1h |
| Total | 360 | 6h |
