I was testing the TAL200K after a another modification. Yes used Eta Carina as a test.

Details
TAL200K with Hutech FR #7887 1800mm FL f/9, Canon 5DH and Hutech LPS filter. FOV is 1.14X0.75 degrees. Seeing was about 5.
ISO 500:-- 1X(8s, 15s, 30s.)
ISO 1000:-- 3x(30s, 1M, 2m) 9x(4m, 8m)
RAW to TIFF and correct for flats with ImagesPlus. Stacked and aligned with Registar. Used EasyHDR to produce a HDR image.

What is interesting that in no single exposure is there any 'detail' in the region round Eta Carina, just a featureless ellipsoid. But the HDR image seems to have managed it. I have put up the same region from the Hubble widefield as a comparison.

What do you good folks think? Is it real? There is also a crop of a one second exposure of the Trapezium to give you an idea of the seeing conditions
