Here is another composite of RCOS and RH305 data. The RH305/STXL 16200 combination did a wonderful job of being able to frame all four galaxies as well as pick up some gorgeous galaxy clusters off in the far distance.
Wonderful image Martin. Is it mainly RCOS data and the Honders was for the background field? I like the way you are combining data from the 2 instruments.
Not entirely happy with the size limitations imposed by a Squarespace website, I have now created a separate link to a full sized version of the image on my previous site, here:

Can I ask a question. I have posted images in the past that have very black backgrounds like that and have been critiqued that the night sky is charcoal not black or that I have black clipped my image (I probably did a bit).
What's your take on that? I notice your images tend to have very black backgrounds (not a criticism as I like black backgrounds). Its great for making the galaxies etc stand out.
Greg - Colour calibration is getting harder and harder. For example, under Windows 10, there are two 'photo viewers' the original (Windows Photo Viewer), and now 'Photos'. Each of these programs render the same image differently, with the latter making it much darker and more contrasty, whilst the former renders the image correctly in my view.
If my images appear to have overly black backgrounds - it is a rendering problem as I always strive to give a slightly charcoal'ish background and always check the black point so that clipping has not taken place. One other thing occurs also in Photoshop CC17 is that it appears to double up the sRGB profile (making things dark) even though you have not selected that option.
So you have to be very careful - and I use Windows Photo Viewer right now to see if my web preparation has gone as planned by downloading the image from my own website and viewing it in that program.
As mentioned though, IOS cannot render the sRGB colour gamut so images appear very dark/clipped.
