Description

as I promised, we insisted on this object in 3 different nights, one in a pleasant company of our friend and astroimager Giorgio Ferrari ( http://www.astrobin.com/users/GiorgioFerrari/ ) and gentle companion, they have pampered us and we greet affectionately ♥ :)

In this latest version it appeared sharper weaker nebulosity around the Flame nebula, on the left of the big star Alnitak, and under the famously dark nebula "Horsehead", right.
For a total of just over eight hours, I selected seven hours of best-frames, made on November 26, December 31, 2016 and the night between 4 and 5 January 2017.
With the faithful Super-apo 130 / 910mm Tecnosky and a Canon EOS 600D on HEQ5 mount, partly realized from Veirera (SV), in part from Tiglieto (GE) (single shotss from 3 to 5 minutes @ 1600ISO )
