Messier 92 (NGC 6341)
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 globular cluster Messier 92 located in the constellation Hercules.
The images were taken with the following equipment:
| Location | Rowe, New Mexico |
| Telescope | Takahashi FSQ-106 |
| Focal length [mm] | 530 |
| Focal ratio | 5 |
| Mount | Paramount MyT |
| Camera | QSI 683-WSG-8 |
| Filter | R:G:B |
| Exposure time [min] | 105:140:120 |
| Resolution | 2.08″/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 21.5 magG (DSSR 15).
The three highest redshift quasars [Flesh 2015] in the image are:
SDSS J171822.76+423945.2 z=2.90 magG=21.2
VPM J17160+4330 2=2.90 magG=19.8
VPM J17197+4309 z=3.20 magG=19.2
