here's Hickson Compact Galaxy Group 68 along with NGC 5371 with a bonus supernova

(a bit late posting this one, but there are some interesting things, so better late than never):

NGC 5371 with SN 2020bio

interestingly, my standard 5 nm Ha filter failed to enhance HII regions in NGC 5371, a wider filter was required.

NGC 5371, Ha 12 nm:

image details:
FS102 OLV @ 627.8 mm,
Starlight Xpress Trius 694, 1.49"/Pixel
astrodon LRGB E-series filters
switched from astrodon 5nm Ha, to astronomik 12 nm Ha
ASA DDM60

more details and larger images in this blog entry

 

thanks for looking

Well done, and I appreciate your detailed write-up on the blog post.  I particularly like your attention to the redshift details vs. your H-alpha filter bandwidth.  That was going to be my question, and you answered it very well.  Thanks!
