Description

I did this image from several series of shots gotten during the period between end of may to end of july, because the window of sky between the trees was a bit narrow. Yes, Rho Ophiuchi stays not very high at 45° lat...
Sometimes the moon light was too hard, sometimes the sky was not clear, so I had to sort the best ones to get a correct integration.
Unfortunately, I failed to put the camera on the same orientation angle of the camera on all series, so... I had to crop a lot!

I used my QHY163M camera coupled to a Samyang 85mm lens, and Optolong RGB filters.
I kept about 60 shots of 1' for each channel. Treatment by PixInsight.
