NGC 3184

The "Little Pinwheel" galaxy in Ursa Major.

 

I've been trying an experiment using narrowband for green and red (Oiii and Ha), but from now on I will abandon narrowband on the SCT. I can't seem to get enough signal overall even with longer integrations and narrowband targets seem to fit the low FL scopes better.
