I think a temporary over brightness (not complete blindness) would actually be more realistic and also could serve as a way of changing the odds in a dogfight.
Bit to 'starry' for me I am afraid but certainly not bad.
I think chromatic abberation with 'fringing' is a good technique for making bright sunlight appear realistic.
But essentially as long as you are blinded temporarily when looking directly at a star I am not too bothered what it looks like. It would be good if flying towards the sun could fool the dumber IR missiles and perhaps put off lesser enemy pilots from following your moves a little bit, especially if you could employ some shading to your cockpit to avoid being blinded yourself.That could enhace the gameplay during dogfights a bit I would think.
