Leo triplet (Messier 65, 66 and NGC 3628)
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 galaxy group „Leo triplet“ located in the constellation Leo.
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 | L:R:G:B |
| Exposure time [min] | 615:540:555:450 |
| Resolution | 2.08″/px |
Data calibration and registration and the final processing was done with PixInsight. The result was as follows:
Leo Triplet
Leo triplet annotated
The faintest star in this image has an apparent magnitude of 22.6 magG (DSSR 15).
The two highest redshift quasars [Flesh 2015] in the image are:
SDSS J112006.49+135559.1 z=4.05 magG=20.7 (Gaia DR2)
SDSS J112018.38+132620.0 z=3.82 magG=19.1 (Gaia DR2)
