Fornax A or NGC1316

SPX350 F4.53, ATK-16HR, Astrodon LRGB filters. LL RGB.

L=3hrs 40m in 10min subs.
RGB=6x5min each.

This is quite a bright galaxy pair at similar distance of 60 mil lyrs. My first lenticular galaxy thought to have merged with other galaxies and consists of old stars with no HII regions but with typical dust present. I used Strongmanmike's image as a guide and it looks like this one needs plenty of subs to show the density waves. Second galaxy has a blue ring of starburst owing to minor interaction with bigger Fornax A. Like Mike I thought I would compare dust with HST result to see what I managed to get.

Would have been interesting to have tried IR filter so see if it revealed more dust?

Thanks for looking.
