Shot over about 5 nights little by little; this year the sky is only given along with cloudiness.
I shot the stars separately and didn't crush them too much or improve them with terminators (just a little), so to speak — a "cozy version".
Stacked with drizzling 2, cropped, processed, and reduced the resolution.

How did the Scorpions perform? A worthy product? After all, the design is fast, there's no situation where they weren't working at full capacity?

Good filters, no halos, honestly I didn't notice any drop in transmission, last year I shot with the Antlia for fast systems, roughly the same thing. And my focal ratio isn't 2 but 3.14.
