Hi Rolf, as many have said, great work !

Yes, it can be difficult to pick out any Intracluster light from the Integrated Flux Nebula. I've aligned a (linearly stretched) image from the WISE survey (12um W3 band) which may help.

In the survey image you can see many faint bands and patches, including a slightly brighter patch to the right of NGC 3258, which may confuse the identification of a intracluster bridge to the NGC 3268 group.

Based on the published radial velocities in the Principal Galaxies Catalogue and measuring the angular distances between NGC 3258 and 3268, these two galaxies are probably 1-2 million light years apart, so there could well be a stellar stream between them. There's quite a large difference (about 1000km/s) between the radial velocities of NGC 3258/3268 and 3269 which would normally mean that NGC 3269 is about 50Mly further away. However, it's more likely though that the large difference in radial velocity is just relative motion within the cluster, so there could also be a faint intracluster bridge between these galaxies too.
