It's been a while, but I thought I'd process another image from the RASC Robotic Telescope. I started working on this image in October, but ran into some challenges incorporating the Ha data. After finishing my
M33 with Ha added, I figured I could use the same technique here, and I'm satisfied with how it worked out.
I have offset the framing of
NGC 3718 to emphasize its interaction with
NGC 3729, seen in the upper-right. It is believed that they interact gravitationally, which has led to the unusual shape of NGC 3718, which would likely otherwise be a regular spiral galaxy.
Also included in this image is the
Hickson Compact Group 56, just above and to the left of NGC 3718. Despite appearances, HCG 56 is roughly 8 times more distant than NGC 3718. I found it difficult to resolve much detail for this group.
Many thanks to the RASC Robotic Telescope team for the data!
