I will start by saying that I can not find a name for this as a distinct object. Broadly it is part of the Chaemeleon molecular cloud complex. Solving it on astrometry.net reveals no catalog numbers of any sort. I had a go at this to test how the ASI2600 would go against a dim target and found it by browsing around in the Voyager virtual field of view. I would say that answer is that the camera performs well picking out a dim target! I tried collecting HA as well, but it is virtually absent, there is a little red'ish knot in a darker area which brightened up somewhat and that was that.
This is 94 X 600 second subs taken over three nights with the ASI2600MC and Stellarvue SVX80T. Integrated in APP and a fairly light touch of post in Photoshop.
Thanks Peter, I have been really surprised by the reaction to something that I really imaged on a whim. I thought about CED111 but decided it was too obvious and too bright for what I was trying to test out, so I poked around with the virtual FOV tool in the Voyager web dashboard and thought this looked interesting.
This really showed that integration time is king. The result from two nights (Just under 10 hours total integration time) was not nearly as nice or smooth. Apart from an equipment issue I would have had 20 hours over four nights! I may spend another night on it yet just to see if I have hit the point of diminishing returns.
It was nice to prove that the ASI2600MC does not have the background artifact issue that limits the ASI294MC. That seems to be related to the bayer matrix itself, I suspect some sort of interfereometry like effect going on.
That is my take on it. I am waiting on a new ASI2600MM and might use that to create a good luminance layer with a clear or lum filter (I have both so it will be interesting to see any difference between the two)
Thanks, I do hope to try for another improvement with a good luminance layer when my new camera arrives, but there is probably little point in adding NB data. I tried some HA on it and lets say that you wouldn't bother on this target! I should have an OIII filter soon so I might have a sniff with that too. HA attached here.

Thanks. I am still quite surprised by the reaction to this image, I can't say I picked it out at random (Quite) but it was close to it. But it is nice to image a less popular target. It is about at my limit of elevation before the LP from Melbourne would start causing nasty gradients, but I hope to poke around the area a bit more.
I don't know what it looks like ....maybe the stuff I found on my coffee cup when I finally went back to the office after COVID ;-), but suffice to say an impressive result akin to discovering a new previously unknown species!
