Great shot Doug
The field is perfect for that region and you have framed it nicely. Would be worth investing the time to capture the other wavelengths to add to this, don't leave it here.
I'm not sure you have over sharpened it but maybe the contrast is a tad high? Some of the brighter areas look to have lost some gradations in brightness perhaps..?
Would you think this is a better camera than the QHY then..?
I like the image
