I would like to thank you Admiral Nelson and Herra for taking the time to set up the stars for the main campaigns of FS and FS2. From the images I see of the stars, it looks like they came out just right. Betelgeuse is is positioned perfectly IMO... the distortions of light caused by the nebula really seem to give the supergiant a pulsating, nonuniform appearance.
I see that the retail stars might be too large to be pure replacements. That completely slipped my mind, so if it is necessary I will resize the retail star images to 512 x 512 without losing quality. The same goes for the supergiants, and now bright giants which I have just completed. While the stars are positioned perfectly, they do seem to be a little on the small side in-game (with the exception of Betelgeuse). I know that one of the underlying reasons might be because the supergiants would otherwise be too close to the user, making the environment hostile and uninhabitable. But in this situation, I think its okay to sacrifice realism for eyecandy. If it's because my images are too large and would otherwise appear way too big in-game, I would be glad to resize all of the images.
One other note I would like to make is about Polaris. Did it originally reside in a nebula before I made the new star? It's not a big deal really, but even though it is a supergiant, it hasn't evolved to that stage where it ejects large quantities of matter into space to form a circumstellar shell. Also, Polaris Ab is positioned fine, but can it appear brighter? It's only 18.5 AU from its larger companion, and should appear about 7000 times brighter than a full Moon from that distance. At 2400 AU, the third component of Polaris, Polaris B, would appear 40% as bright as a full Moon from the supergiant.
I again appreciate the help I have been receiving. Go ahead and let me know if the files need to be resized. Thanks.EDIT:
From left to right: Albireo (Beta Cygni), Alphard, and Mintaka (another O type star between 15-20 solar radii in size).
I was meaning to upload this after I posted my last message as an update just as I am doing now, but I fell asleep during the process. While you think about how that might have appeared from my end, here are a few words on the two bright giants.
Albireo (Beta Cygni):
A spectacular double star, Albireo can be seen as a mix of bright orange and contrasting blue. While two components of the system can be made out visually, Albireo A is actually a spectroscopic binary. Basically, this system is set up very similar to Polaris. The difference is that the smaller companions of Albireo Aa are going to appear much brighter than they would for Polaris Aa, since the companions are of a younger, more energetic spectral class. To be specific, Albireo Ab would have an apparent magnitude of about -23, about 4.2% of bright as the Sun viewed from Earth. At more than 4000 AU away from Albireo A, Albireo B would have an apparent brightness of -13.8, about 3 times brighter than a full Moon.
Although white dwarfs are dim compared to their stellar companions, these "stars" do emit light and can appear very bright in the sky of a nearby companion. Assuming that the white dwarf companion of Alphard is roughly 50 AU away from the bright giant, it would appear more than one third as bright as a full Moon.
Although not featured in FS, it was in the Wiki and can be used by anyone if they desire. This system is very complex, and is made up of three components, A, B, and C. Mintaka A is an eclipsing binary, consisting of Mintaka Aa (an O type bright giant), and Mintaka Ab (a B type giant). The stars take about 5.73 days to complete one orbit around each other, leaving the stars with a separation of one tenth of an AU. So these two stars should appear very close to each other in-game. Mintaka B orbits the center of mass of Mintaka Aa and Ab 73 AU away. At this distance, the young star would have an apparent magnitude of -24, or about one tenth as bright as the Sun as viewed from Earth. Even further out at nearly 15000 AU away lies component C. Mintaka C is made up of Mintaka Ca (a B type main sequence star) and Mintaka Cb, (another main sequence star). Separated by about three tenths of an AU, the energetic pair would appear more than one fourth the brightness of a full Moon.
I provide this information to give anyone ideas on how these star systems should appear in-game. I usually make references to the angular diameter of the Sun, and the brightness of the Sun and a full Moon. To provide a form of reference, the Sun and the Moon both appear roughly the same size in the sky with an angular diameter of one half a degree. The Sun is over 400,000 times brighter than a full Moon; a full Moon is over 20,000 times brighter than the brightest star in the sky, Sirius. Sirius is over 20 times brighter than Polaris.... and so on. Just use your imagination and your artistic license to make realism look good.
Also, I have been providing large images of companion stars to make it possible to switch up the scenery in different missions of the same system. This is why I have been mentioning how large the main component of a system would appear from its companion, such as Antares A and Polaris. What do you all think?

I recently updated the BrightGiants.rar file to include one other bright giant which I overlooked in the Wiki, Alphard. The file should now be up to date, so if you downloaded this file prior to the update and you would like to have the extra stars, please redownload it. Color values for Alphard and its white dwarf companion have been provided.
