| Comments |
... Rather dissappointing especially after all the effort that went into this image. ... All channels captured in marginal Seeing conditions. Last year it was smoke, this year haze. ... Guess which channel was the last to be completed? Blue, resulting in a huge gradient and star fringes. ... Interesting dark nebula streamers in the central region. |
