I have finally got a new STXL this last week and this image is a test image to see if the camera is operational. There was a blooming issue which I think is now fixed but I need clear skies to test that with luminance data.
The stars in this image are still not to my liking. I worked more on the guiding and have that looking ok near Carina. The Ha was done prior to new guiding and as such the stars are not great. However, I am very happy with the detail level. Many features seen in Hubble images can be seen in this image. Happily I can say those features are pretty sharp looking.
The field flattening is still not at the correct distance and I have done a mild lens correction to this data to make the stars a little more round.
