Thank you all for the replies! I will check out those nebulae as well as the messier45 site.
Concerning SN, I was just trying the tab "Labels" and the nebulae are greyed out (I didn't specifically search for "nebula"). I am positive it worked in the past, just a few weeks ago when I bought my scope. When you "label" something in SN basically it shows all names on the screen. I don't always label everything of course because otherwise it becomes too crowded (it is a laptop, so the screen is not huge...)
Thanks again!
