47 Tuc image is doubled

[10110111]

The following screenshot was done with stars and the Milky Way disabled. Two issues are apparent, compared with nebulae/default/smc29-2.png, which contains an image of 47 Tuc:

1. Many of the stars have fainter copies nearby (enabling stars will show that there's one star instead of two);
2. The middle of 47 Tuc is blown.

This may imply that there are two different images a bit displaced from each other (the blown middle would then be because of addition of two bright images). I tried disabing all DSS checkboxes, but this didn't change anything. Not sure how to find which image is the second one (the first one being made of smc29-*.png).

Removing smc29-2.png from the installation prefix confirms my conjecture about there being two images:

Still need to find which is the second one.

SMC?

SMC?

I have no idea about the naming scheme of the images.

Please remove texture for NGC104

SMC = Small Magellanic Cloud

Please remove texture for NGC104

Yeah, that's it. After removing it along with smc29-2.png there are no remnants. Since the SMC texture has a better-resolution image of NGC104, I suppose we should simply remove n104.png completely.

Please update the CREDITS.md and textures.json files after removing texture also

[10110111]

CREDITS.md doesn't appear to mention NGC104 in any form.
