Messier 75 (NGC 6864)

The images were taken with the following equipment:

Data calibration and registration and the final processing was done with PixInsight. The result was as follows:

M75 annotated

In the field were quiet a lot of quasars. The two most distant of them (see annotation) are:

WISEA J200544.04-215732.6 with a redshift of 1.9

WISEA J200602.41-221019.6 with a redshift of 1.3
