NGC 7252
From time to time I obtain data sets from remote observatories. One of my favorite providers is Telescope Live with telescopes in e.g. Chile, Australia and Spain. One of the data sets I received, was data from the galaxy NGC 7252, located in the constellation Aquarius.
The images were taken with the following equipment (Telescope Live CHI-1):
| Location | El Sauce Observatory, Chile |
| Telescope | Planwave CDK24 |
| Focal length [mm] | 3900 |
| Focal ratio | 6.5 |
| Mount | Mathis MI-1000/1250 |
| Camera | QHY 600M |
| Filter | L:R:G:B |
| Exposure time [min] | 160:150:160:150 |
| Resolution | 0.39″/px |
Data calibration and registration and the final processing was done with PixInsight. The result was as follows:
In the field were quiet a lot of quasars (see annotation). The two most distant of them are:
MQ J222014.52-244302.3 with a redshift of 2.4 and an apparent magB of 20.98 (2017,PASA,34,25).
MQ J222002.13-244853.1 with a redshift of 2.3 and an apparent magB of 20.74 (2017,PASA,34,25).
The faintest object in this image has an apparent magnitude of approx. 22.4 magB (2017,PASA,34,25).
