The attached STX list contains 44 red supergiants with apparent magnitude 8 or less (on average in case of variable stars). Most (35) are of spectral type M with the remainder of type K.
They owe their monster status to their enormous hefts and luminosities.
That is a great list, thank you for sharing. I made a list of super giants a while back, but for some reason it doesn't show in my list anymore . This saves me rebuilding it.
Have you tried using ST4v's Database Power Search (DBPS) to make similar lists? Of blue stars or α-Cyg stars, etc?

Yes, I have and found DBPS to be very helpful in some cases. My first choice tends to be SIMBAD because it gives me the coördinates and other attributes as well.

I need the coördinates for other applications and haven’t found a way to extract them from ST4. Let me know please if there is a way to do that.
Bye, tiha
SkyTools is generally meant to be self contained. But there are various ways to extract data. But they all depend on the context. If you could explain what data you want to extract, and in what form, then I may be able to help. By form, I mean, like if to a file, then in what format? Or maybe copy/paste?
yes, I noticed that concern about ST4 being self-contained :-)
I do appreciate a reasonable degree of completeness in software but since it can never be absolute (nor is there need for that) I am also looking for easy exchange of data between applications. This may just be an idiosyncrasy of mine so you may want to check with other users.
Having said that, let me illustrate one of the reasons why I like to use SIMBAD. As a QGIS user I favor the map paradigm over the list paradigm. ST4 has some great maps/charts but I cannot, for instance, see the objects in one or more observing lists mapped to the horizon of my location at a given time. With QGIS that is easily accomplished — provided that I have the coördinates. Hence SIMBAD.
For this particular purpose, all I would need in ST4 is the ability to export an observing list as say a CSV file with four columns: designation (just one, the most common), type of object, RA and DEC (both preferably in degrees).
That would be great but you may need to determine whether this if of help to others.
Mind you, even if you provide such a facility, I will continue to use SIMBAD because of all the other capabilities that it offers but I would never see that as weakness of ST4.
