Hello everyone,

I just got my first serious astrophotography rig delivered (coming from an S30 Pro) and first thing I did was take flats to see if the gear is okay.

What concerns me are the splotches on the preview window in the ASIAir app. They look like there is something horribly wrong: https://i.imgur.com/GHZA7oV.jpeg

But then when I look at the flats in Siril/PixInsight, I can't see them. They seem almost too perfect?

Here is a Google Drive with a few of the flats as FITs: https://drive.google.com/drive/folders/1fCq783KUXvjKIwexxDHlkYxdYKrdM52B?usp=share_link

I used an iPad with a white sheet of paper. Tried with a tshirt, got the same result.

The relevant specs:

• Askar 80PHQ
• ASI2600MC Air
• No filters for these flats

Really appreciate any advice.
