Abell 33 (Diamond Ring Nebula) from Telescope Live CHI-1-CMOS
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 LRGB and HSO data from the planetary nebula Abell 33, located in the constellation Hydra.
Data calibration and registration and the final processing was done with PixInsight. The result was as follows:
In the image you can also find some quasars. The most distant of them is:
SDSS J093957.08-024301.1 with a redshift of 2.396 and an apparent magv of 21.2 (SDSS DR17).
The faintest star in the image has an apparent magnitude of more than 23 magv (SDSS DR17).
