Description

After 2 weeks of clouds/rain - finally last night & this morning clear. This is the IC 4592 & IC4601 nebulae. The IC4592 / Blue Horsehead Nebula is a faint reflection nebula in Scorpius composed of very fine dust that normally appears dark but can look blue – in this case from the reflected light at the eye of the horse (Nu Scorpii star). The second reflection nebula - IC 4601 – can be seen surrounding two stars above the image center.

EQUIP : Canon 800D, Canon 200mm fix lens at f/3.2 on an iOptron Skytracker Pro. IMAGES: 16 subs @ iso800 x 200 secs. PROCESSING: The subs and calibration frames were stacked & pre-processed in Pixinsight and final processing in Photoshop. 25 Aug - 23h30.
