Eridanus spiral NGC 1232

Catalogued as Arp 41, or NGC1232 and 1232A This is a beautiful magnitude 10.1 SAB(rs)C face on spiral, with a smaller SB(s) 15.2 magnitude spiral companion.
This is a beautiful object visually in the 25", and although I have several records and descriptions in my notes over the years, I had completely forgotten this object until I was browsing the Herschel catalogue.
Details are 16"f3.6 newt on an unguided direct drive mount, 10km from the Perth CBD. Camera was a QSI683 struggling to stay below -20C, and over about 4 nights I was able to get about 40 5 minute subs per filter to produce this.
