After repairing my Atlas (EQ6), having waited for an opportunity for the sky to be finally clear and almost stable, I was able to focus on a target that was close to my heart:
I wanted to use a large focal length to have a fairly small sample and thus to detail the jet that is expelled from the central black hole of this elliptical galaxy.
To live next to a monster like this must be a bit tense!
I used a 300mm F4 newton OO telescope, a 2.5x barlow and my little ASI224mc. There were 3 sets of catches on 20, 23 and 24 April.
After making a severe selection, I kept that 17000 frames of 1s, almost 5h.
The treatment was done with Siril, the best software for the fast sky anyway! fast and accurate. Thank you Cyril!
