I believe this is the is the first time this pair has been imaged and published by an amateur.

NGC 3100 and NGC 3095 are actually part of a four-part arc of peculiar galaxies. These two are generally categorized as a non-interacting pair. It is not known whether they are a physical pair or are merely optically paired.

NGC 3100 (upper left) is classified as a weakly barred lenticular galaxy. However, careful study has shown that the galaxy has weak asymmetric spiral arms in the outer disk, which might make it analogous to “late-type” spiral galaxies. You can faintly detect the spiral arms in this image. The image also shows dust lanes and a tiny companion galaxy. All in all, a complex and interesting example of a galaxy midway between the ellipticals and spirals.

NGC 3095 (lower right) is classified as an (Sc) spiral, in which a galaxy is relatively bulgeless and the arms are patchy. In this image you can faintly see HII regions.

The Catalog of Southern Peculiar Galaxies and Associations, by Halton Arp and Barry Madore classifies NGC 3100 and 3095 as a peculiar galaxies, because they meet the requirements of category 24 (close pairs and triples).

This pair is difficult to image, because the angular sizes are small. NGC 3100 is only 1.9 arcmin and NGC 2097 is 1.6 arcmin.
