Finally got just enough data to image this beautiful region - been trying for 2 years, but the winter sky has prevented it till recently. Seeing was just good enough and it was a real thrill to get something nice from the new camera. There are some filter reflection issues, but they are fixable and are acceptable for now.
Very nice Ray, lovely larger galaxy down the bottom and scatterings of tiny ones throughout the field.
The high res version is wonderful to look around
Truly excellent, Ray. Stunning. A wide enough FOV to get the globular in the image, but also to see the sharp details of the face-on spiral at the bottom. Great work.

That is a superb image Ray, the stars are absolutely perfect as well.
My hat is off to you sir.
Now that is a definitive image for this new camera. You should spread that around as an example of what it can do in the right hands.
How long though did it take to process all those images? Is there special software that stacks them all quickly? CCDstack would laugh at me if I tried to stack that many images.

Nice, very nice image. There is so much to like. I really like the star colours, subtle but evident, great detail and not over sharpenned. Resolution in the globular is superb and I really like the whispy detail in the reflection nebula.

thanks for the kind comments M&T. it is good to have a camera with enough real estate to catch a bit of this type of scene.

Hi Greg - great comments, thanks. The data handling took a few hours from memory (did not measure though). flat and bias cal in Nebulosity (very fast), alignment, stacking and processing in PixInsight. I have a fairly modern quad core i7 with 16G RAM, which is probably almost a necessary adjunct to this chip - have recently processed a run of almost 1000 ROI subs with no dramas using PI.

Absolutely stunning Ray.

Thank you Scott. Yes, the camera has it's own idiosyncrasies, but it is fundamentally a very capable design - full marks to ZWO for getting to a high standard with their first big DSO camera.

Thanks Paul. as you know, clear sky has been a bit hard to find down this way, so it was pleasing to get enough to produce an image. I didn't do any sharpening - the main feature of this object is the soft cloudiness - appreciate your comment on that
Ray, That is a very fine image. You picked a great target to test your camera on, it has everything in it. Has both high and low signal areas, reflection nebula, with a nice stars everywhere, and great colours.
Oh that's a lovely shot kinda like an all you can eat buffet so much to take in.
All round image looks smooth and sharp amazing detail for 60sec subs noise looks completely absent
Yeah really great shot Ray I can see the minor reflections you mention but they don't look obtrusive, in fact they look quite nice Did the short subs help reduce star size at all? did you dither?
Very nice Ray, i like the clarity and detail in getting HH98 to appear so clearly. It is easy to assume its a galaxy, as there are so few of them in the southern sky. Must get back to this object soon.
Gain setting at 139 given that sub length, or less?
Thanks.

thanks Terry - yep, it is a great region to image - had fun.

thank you Michael. I was pleased at the relatively low noise - still some of course, but not a lot. 60 sec subs are normal for this camera - makes for a whole lot of data.

thanks Mike. I assume that the short subs helped with the stars, but did not check - the seeing was not great though, just good enough. standard procedure with the current setup is to do a flat/bias cal and dither to take care of everything else (the dark current is negligible and the read noise is almost unbelievable). It is really weird how quickly this camera has become second nature - I really don't think about it any more - 60 second subs already seem quite normal.

thanks Simon - I am sure that you will enjoy the camera. What filters and wheel are you getting? I am using 1.25 filters and they work OK at f4 (just), but if I was starting from scratch, I think that I would go for 36mm.

Thanks.
gain was 100 - I think I will leave it at that setting unless there is something really challenging that needs very short subs. I was also happy to see the HH - icing on the cake.
