Visibility IV / V
I decided to illuminate the famous ‘Lion Trinity’ from the spring galaxy sky.
The intention was to illuminate for so long as to bring out the tidal tail of the NGC 3628 galaxy. 20 hours was the goal, but from the data I brutally worse off that the result was 'only' 17.5 hours left.
Despite the amount of exposure, getting the tail out was painful and the background sky could have been better.
However, as a bonus image, I got an X-ray from the NGC3628 galaxy and a few quasars. These are marked in another picture.
More information about the tail and quasars here .
Edit: 13.5. I added another processed image.
