I would like to show, through this drawing, how the seeing is important to observe and describe very little objects.
Object: NGC 1999
Object type: reflection nebula and globule
Date of observation: 2011 10 01
Length of observation: 60 min
Height of object above horizon: 28.5°
Observing site: Observatoire des Baronnies Provençales (Southern French Alps)
Observing conditions; exceptionally good, mag limit 6.7v, SQM 21.50, FWMH 0.9” !!!
Instrument: Dobson Obsession 25”
Eypiece: Ethos 6mm, without filter, power 520x
Notes: I am astonished: at the eyepiece, I have in front of me a delta winged aircraft, perfectly clean. Extremities of wings are curved, the “head” of the craft easely detailleable. The encreasing of bright nebulosities around the head and at the back of the wings have also been noticed.
The caracteristic blue color of reflection nebulae is obvious.
Much more details can be found at www.deepsky-drawings.com

I had the opportunity to look at your work two week ago in Rognes, this one is a very good sample of your style.
Superb Bertrand. NGFC1999 is one of my favorite object which I call the “human bust”. Your drawing represent very well what I see at the eyepiece of the T560.
Very impressive big scope, dark sky sketch.
