Title: NGC 7098 in Octans

Here's an interesting little galaxy in Octans.

[From the ESO website] NGC 7098 is an intriguing spiral galaxy with numerous sets of double features. The first of NGC 7098’s double features is a duo of distinct ring-like structures that loop around the galaxy’s hazy heart. These are NGC 7098’s spiral arms, which have wound themselves around the galaxy’s luminous core. This central region hosts a second double feature: a double bar.

NGC 7098 has also developed features known as ansae, visible as small, bright streaks at each end of the central region. Ansae are visible areas of overdensity — they commonly take looping, linear, or circular shapes, and can be found at the extremities of planetary ring systems, in nebulous clouds, and, as is the case with NGC 7098, in parts of galaxies that are packed to the brim with stars.

Integrated Flux Nebula (IFN) occurs throughout the area, as well as many background galaxies.
The FOV is 45' x 42'.

Very nice, Geoff!  Not a common target and well captured and processed.

Hi Geoff!
Congratulation for finding this nice object and for capturing and excellent processing.
Glad you also captured a few of the weak molecular clouds around this object.

Nice one Geoff.

Seeing all those other galaxies in the image is a big wow for me.

Thanks
