Description

NGC 3717 in Hydra
This one came as a real surprise.
I started doing NGC 3717 at the end of the last  new moon phase and as the moon was up I added a couple hours of Ha.
There is not much Ha in the galaxy itself but I noticed some faint wisps in the background.
I added some Ha data the last two nights so all in all its about 10 hours.
I couldn´t find any reference to it but it almost looks like an SNR.
The noise level is a bit above what I would normaly accept but thats the price you pay when enhancing faint signal.
The whole image is a LRGB Ha 180 60 60 60 600 min.
I hope you find it interresting.
Wolfgang
