The colour does lean to some extinction by dust and gas,siumilar to the sn earlier this year in NGC5128 AKA Cent A.
Nice image.
Cheers

Thanks, Ron, that makes sense.

A great rendition M&T! Vibrant detail and colour!

Cheers, Marcus

Thanks, Marcus!

We think it's an improvement on our previous effort from a couple years ago. Accumulated tiny improvements perhaps. Refocus between subs, much longer total exposure, flats using a big electroluminescent panel, statistical outlier rejection, and luck.

The reflection from upsilon 4 eridani is annoying. Tonight we're doing the Flame Nebula, with Alnitak right there in the frame, and no problem with reflections at all in a short test sub. The problem must be only if the source star is a degree or so out of field.

Best,
M & T

That's similar to what I've discovered also. Even when doing terrestrial night photography. If there was a streetlight just out of frame it would flare so I used to put the buggers in the frame to stop it.

We spoke too soon. See our next post, on the Flame Nebula, which has at least six copies of Alnitak. Rats.
