Description

Back to basics at the Ursa Deep Sky star party with manual focus and an intervalometer. This was also an experiment to reduce the effect of "split star haloes" towards the edges of the field. The lens had an aperture mask that reduced the effective f-ratio to about f/3,3 and some fishing line in front of the objective to get nice spikes.
