As if in a bluish tint.

Previously, this Laniakea 425mm was around f/3.5, but now it's f/2.9. Nothing else changed in the technical information.
Is it a different coma corrector?
And as I understand it — this is a mosaic?

No, it's not a mosaic. A year ago, I swapped the 1.0 corrector for a 0.85 reducer, changed the camera from a 533 to a 2600, and now use Antlia narrowband Highspeed filters.

The camera has a resolution of 6248x4176, but the image is 8705x5818 — how does that work? Drizzle?
I figured out the mosaic — I dug into Stellarium more carefully.

Yes, drizzle.
