NGC 6563 with and without the AOF

The slider view allows you to compare the effect of turning on the AOF. The planetary nebula NGC 6563 resides in a crowded starry region of the sky. In natural sky conditions (left) many of these stars remain invisible due to the blurring effect of the Earth’s atmosphere. When the AOF supplies its superb correction (right) a myriad fainter stars become visible, together with a sharper view of the dusty parts of the nebula itself.
