Hi all. I sketched M22 under dark sky. (Limiting Mag. 6.0)
I saw some ‘dark lane’ in this cluster..
It is real? or illusion? I’m not sure

One thought on “Dark Lanes in Messier 22”

  1. Nightwid,

    Real or not what does it matter as long as you sketch what you see in the eyepiece.
    I’m of the opinion that some dark lanes are due to regions of lower stellar density and magnitude.
    You sketch is excellent.

    Frank 🙂
