Description

I just finished Abell 39 recently. Abell 33 looks a lot like it. This time of year comes with a lot of clouds and was not able to gather the integration time I was hoping for, but was pleasantly surprised how much detail in OIII I was able to still pull out.

Abell 33 is a spherical planetary nebula in the southern constellation of Hydra about 2,700 light years distant. It has been described as a diamond ring due to the bright star (HD83535) at its rim. This star is not part of the nebula, being in front of it in our line of sight. The inner structure has similar dark and light features as the northern Owl planetary nebula, M97. The outer envelope is a distinct rim. The primary color is due to strong emission of oxygen (OIII). The hydrogen (H-a) signal is much weaker, which I did not bother to capture.
