The Tulip Nebula (Sharpless 101) is an emission nebula in Cygnus.
It lies at an approximate distance of 6,000 light years from Earth and has a linear diameter of about 70 light years.
It's apparent magnitude is 9.0 and it occupies an area of 16 x 9 arc minutes of apparent sky.
I used HSO palette with RGB stars. More than 33 hours of integration time, selecting only the best frames of the total valid frames captured (80%).
All c&c will be appreciated.

If this user has been harassing you, and you shadow-ban them, all their activities on your content will be invisible to everyone except themselves.
They will not know that they have been shadow-banned, and the goal is that eventually they will get bored while having caused no harm, since nobody saw what they posted.
You will remove your shadow-ban on this user, and their comments, messages, etc, will appear again on your content.
Such limitation improves the website as a whole by discouraging people from creating fake accounts to like their own content. Thank you for understanding!
