You read my mind. I was planning on attacking the supergiants first, since they are at the very top of the luminosity class hierarchy. I chose to do Deneb first only because I had mentioned it towards the beginning of the thread
I have finished Deneb, and it's appearance is exactly the same as the image on the first page. I'm very happy with the luminous appearance, but I would appreciate if someone would finalize the image. What I plan to do is provide the new images of the stars as I finish them, along with stating the RGB color values used for each star. I can only go so far as to create the basic outline of the star, such as what I have done with Deneb, and hand it over to someone with more experience who can really give the stars the artistic touch that they need. In the case of Deneb, I would like to give the star a "supergiant" appearance without having to resort to making the star take up half of the sky box. This is a little difficult, because I think I would need some form of reference (i.e. the Sun) in order to show just how large Deneb is, and I don't see how this would work in FS. I think the luminous appearance is just right, but the surface of the star looks a little on the grainy side IMO. I'd be more content if Deneb had a more prominent, plasma-like surface..... what do you all think needs improvement?
As for the size of the image, I do not have the original FS star images to do comparisons, so my Deneb image is very large (2000 X 2000 to be exact). I could easily resize and crop the image without losing clarity, so if anyone could provide the FS star images I would greatly appreciate it. Unless the media vp stars are too small in FS, the new stars are not going to be any bigger than the stars they are supposed to replace. This idea will become unrealistic for supergiant systems with habitable planets, such as Cygnus Prime, but I wouldn't want to make the stars appear so small in the background that the new features go unnoticed. With Deneb's luminosity of about 160000 solar luminosities, we can estimate the average radius of the circumstellar habitable zone (CHZ) for a planet in orbit. This means that Cygnus Prime would have to be about 400 AU away from Deneb. At this distance, given Deneb's +200 solar radius, Deneb would appear about 3 times smaller as observed from Cygnus Prime than the angular diameter of the Sun as observed from Earth.
To an inhabitant of Cygnus Prime, Deneb would actually appear just as bright as the Sun would from Earth with an apparent magnitude of -27.3. However, I don't know how much improvement of detail a FS user would experience with a star slightly less than one third the angular diameter of the Sun. So I think it would be fine just make the new stars no larger than their predecessors unless the predecessor is too small to begin with. What do you all think?
As for converting the images, I'm still having trouble. I think I am going to send the original .tga file, and hopefully if someone does take the image to improve it, they can convert the file, as well. I know it's a simple task, but I'd feel comfortable with someone else doing it who has actually done this before. I wouldn't want to hinder the quality of the image without knowing.
Until then, I will have to wait till I see how large the original Deneb image was so that way I can resize my image and attach it to a future message... (Betelgeuse and Antares come to mind....
