Satellite time-lapse
Image by Martin_Heigan
A time-lapse video of what seems to be a high altitude Satellite passing through my FOV whilst photographing around the beautiful region of Rho Ophiuchi (close to IC 4603).
About this video:
A time-lapse sequence of a Satellite captured in 10 x 3 minute (ISO 6400) exposures, travelling through my wide field Telescope’s view. Note the object’s rotation in the varying line thickness of each 3 minute exposure trail. Photographed in the rural dark skies of the Karoo (Northern Cape, South Africa).
Real-Time Duration: 30 minutes to cross 2 degrees of Arc.
About the Star Colors:
You will notice that star colors differ from red, orange and yellow, to blue. This is an indication of the temperature of the star’s Nuclear Fusion process. This is determined by the size and mass of the star, and the stage of its life cycle. In short, the blue stars are hotter, and the red ones are cooler.
