The IB Tech does have the 81 crawl attached and it has great color, but the stars are pretty much invisible:
Believing it was important to be able to see the stars, we’ve never used this version.
We have actually scanned 8 more 35mm prints of Star Wars (and 3 x 16mm) since that IB Tech was scanned, and all of them have the original '77 crawl. It took us 10 years to find a partial reel on 35mm (which has just the '81 Crawl and Flyover, spliced onto some of Reel 6 - the rest of the print had such bad vinegar syndrome that it had to be trashed). Anyway, we had this new version of the '81 crawl scanned on an LG Scanstation at 5K. It’s faded, but the star field really pops.
One idea is to align and merge the two scans, so that the Luminosity and Star Field from the new scan can be used with the Color from the other one.
Just a few months ago, I also picked up a 16mm print that also has the '81 Crawl:
Interestingly, this is also almost devoid of stars, so perhaps that’s how the '81 Crawl was.
