You will get 6 figures at least for this domain.
- 'Cygnus' is registered in
38 extensions, a huge amount
- it is part of the domain string of many more domains
- there are
dozens of active Trademarks around the world for Cygnus, and many new ones pending - just check the WIPO international database
here
- there are abundant companies around the world, from very small to very large, using this name
- stellar name for all kinds of companies, very versatile as it looks sexy, techie, classy, artsy, spiritual, etc. it's a word that makes a definitive statement
To sum up:
Very visually attractive word for almost any kind of company, especially tech, so extremely versatile; huge number of extensions regged, so obviously already very in-demand; huge number of trademarks, which proves the attractiveness of this word as a brand; and most important, a very large pool of very large potential buyer corporations.
If it were fewer and smaller companies using this name, I'd value it in the mid 5 figures; but with the sheer number of trademarks and large corps using this name already, and considering the size/quality of those potential buyers, I have no problem saying you'll get well into the six figures for this one.
I know you're not in danger from other TM holders, as your company Southcomm absorbed this domain (and project) years ago and you have your own TM on it. I assume that Cygnus project has now been let go, so you're considering your options with this domain asset...
Good luck, beautiful domain
