Messier 27 (DumBbell Nebula)
I have been subscribing to data from the Deep Sky West (DSW) Observatory for some time. DSW is located in New Mexico and offers several fully equipped systems. One of the data sets I received, was data from the planetary nebula M27, located in the constellation Vulpecula.
The images were taken with the following equipment:
| Location | Rowe, New Mexico |
| Telescope | Astro Physics RH305 |
| Focal length [mm] | 1159 |
| Focal ratio | 3,8 |
| Mount | Paramount ME |
| Camera | SBIG STX 16803 |
| Filter | R:G:B:Hα:[OIII] |
| Exposure time [min] | 135:95:120:570:490 |
| Resolution | 1.66″/px |
Data calibration and registration and the final processing was done with PixInsight.
The first image shows of the whole field. Please note the strong Hα signal on the left hand side:
