I'm actually a big fan of these photos, I think they are excellent. They are really amazing but yet they still look like "photos of the sky"!
No offence to the guys who do the type of photos that make it into APOD, they are absolutely spectacular, but those photos imho don't anymore look like "just photos of the sky" if you know what I mean, they look like precisely, painstakingly and masterfully processed and coaxed images, which puts them into a different league.
These pics here are about as good "photos of the sky" as I have ever seen, so sharp and precise but still extremert REAL, I find that extremely impressive, great work!
