Robert may know something about that. Is it a companion galaxy?

The structure is part of the same galaxy. The area you point out is a more vibrant region being less obscured by dust. This also explains why the HII knot is a deeper red. The other HII knots are reddish-pink due to the scattering a blue light from the young stars reflecting of dust. Similar phenomenon as M20 where the Ha area is pink due to the scattering of blue light. NGC300 is believed to be gravitationally bound by NGC55. I'm not aware of any possible companions in the immediate area.

Thanks Peter. Rusty processing have not worked on any images for the last three months. Workflow needs improvement, but it shouldn't take too long to get up to speed again.

Thanks Peter. A few more tweaks the set up will be humming. Guiding issues are now resolved but tracking could be improved. Just pleased to have something on the table at this stage. Thanks for the feedback.
