Description

Jellyfish Nebula

Learned a lot about RASA + Narrowband producing this image.

Shot with Baader highspeed filters at first, I found the detail and contrast was lacking in Oiii. I purchased the Astronomik MaxFR Oiii filter and it made a huge difference!  But the size of the halos produced by the Astronomik filter was smaller due to different focal point/filter thickness. So the biggest challenge here has been removing the halo around the very bright star, Propus, which I accomplished in photoshop post-RGB combine.

In the future I will attempt halo removal on the mono images first in PixInsight.
