Arp 18

[alacant]

Hi everyone

Discovered Arp's catalogue of peculiar galaxies a while ago but it fell into disuse during the hectic nebula days The pdf in the link is formatted in wonderful old html. Here is the catalogue page for Arp 18 with a 200" reflector, with our attempt at a 1960s style plate from our original using an 8" reflector.

Totally addictive. Although not perhaps with an 80% moon.

         

Thanks for looking and so post any Arp you may have had a go at, dslr images especially interesting for us.

I bought this book in the summer of 2017 at a  lecture given on the subject during a BAA  event in our town.  It is en excellent book , the sort you just love to own....

I am not in to imaging, but I enjoy seeing the effort imagers go to.  I think there are a few I might be able to see with a 12" Dob, but not many in this book I think.

Here with 60 minutes more exposure. Maybe a little better? The only advantage from our POV was that it was easier to process with the extra frames; it could be stretched developed more. In StarTools we are mercifully released from the stretch of old:)
