Description

Not something you see every day here. This is the OIII channel of the project I have in process. Basically the companion data to the HA I already shared.

SII is finishing up, and I will share a post of that as well, since I think it is interesting to compare.

Note: There is a UV Emission Source, Lan440 in the upper right quadrant of the image.

Lan 440 (unistra.fr)



If anyone knows more about it, I would be curious to hear. This is not present in the HA and SII data at all, but the OIII seems to have picked it up nicely. 

Per Aladin, it is Mag 19.5!
