New 8K Star Textures

[MrSpace43]

So a few days ago, I started work on new 8k star textures to use for Celestia. So far I have completed 4 star types (one of which is that Sun texture I posted a while ago), and I plan to make more of these textures, and to release them.

These are the textures for the star types I have completed (F-type, G-type, K-type, and D-type)

Added after 44 minutes 40 seconds:
New textures for O-type, B-type, and A-type stars.

After finding some more pics of the sun with large sunspots, I updated my K-type star texture to incorporate them.

New G-type star texture with more starspots.

Comparison between Alpha Centauri A (right) and our Sun (left) using my 8k SDO April 2014 texture:

I think I might update my K-type & F-type textures to have more starspots too (albeit the latter will have less than the G-type).

Added after 4 hours 57 minutes:
The K-type star texture has been updated again, and is now packed to the brim with starspots.

O-type, B-type, and A-type textures have been updated. They now use low wavelength UV data (~304 angstroms):

Okay... how are these installed?

[MrSpace43]

If you mean how they are installed to Celestia, you just move them to the "textures" folder (not the "extras" folder). Then you delete the old star textures that you had previously, and then edit the celestia.cfg file to add the new star textures.

I haven't finished making all the textures needed though, so because of that, they are not available to download for now.

New texture for Y-type brown dwarfs (only works in 1.6.2 onwards) using acrylic pour:

This is easily one of the darkest textures I have ever made.

These look amazing! I can't wait to use them in my install

New texture for T-type brown dwarfs, again using acrylic pour:

Been a while since I touched this topic due to other hobbies and stuff, but after I had a look at this paper, I have updated my white dwarf texture so that it now has surface granules. I decided to keep some details from my old texture that used UV data, so I used it for some bright spots and a few subtle dark patches, just so that it doesn't look dull and featureless when viewed from a distance.

It's been some time since I've done anything with these textures, but now that enough time has passed, I think there are some textures which I think are in need of being revamped.

Finished:
O, B, A, F, G, K, D

In need of a revamp:
T, Y, WR

Not yet made:
M, C, L, Pulsar


T-type:
I'm thinking of making a new texture based off simulations of brown dwarf atmospheres (though I have absolutely no idea as to how I'd tackle making such a texture that resembles these simulations), and I'd also like to see if I can incorporate some bits of magenta into the texture.

Concept texture made using a still from Fig. 27c:

Y-type:
I just imagine it could be made from various bits of Jupiter and Saturn maps.

WR-types:
I'm gonna stick to using ~193 angstrom data, though I'm going to use different Sun images from SDO with more solar activity.

M-type:
Due to a lack of high resolution images of the sun's surface that have licenses which permit commercial usage, I'm stumped with what data I can use for M-type main sequence stars. And before anyone asks, I can't use SDO data because the resolution isn't good enough for large starspots, so the best resolution I can do for an M-type texture with SDO data, is only 2K instead of 8K.

As for L-type, C-type, and pulsars, I have absolutely no idea how I should tackle the textures for these classes.
