Project 49’ was the name code for our second project with the ‘Altaïr of Atlas Astrophotographers’ team, an idea that looked a bit crazy on paper, but that we knew could only be achieved under optimum conditions… The idea was to produce an ultra-detailed image of the Rho Ophiuchi complex, as well as some of its neighbours in the Scorpius constellation, using remotely our setup in Morocco. As this region is about 15° higher in the sky than our home in France, this dream became a reality ! With our instrument in place in the Atlas Mountains, we had to make a 7*7 mosaic (49 tiles), to achieve our goal. A project of this kind already takes up a huge amount of time and material resources (post-processing), so we set ourselves the challenge of producing all our tiles in a single exposure for each filter, without any stacking, and all in LHaRGB using a monochrome camera. 358ly distant.
