I doubt any of the stars would be only 1 pixel wide which is what it needs to be to be affected by the spatial filtering.

Sorry, this is totally wrong. You are perpetrating a misunderstanding. It is NOT just single pixel stars that are affected.

Stars fitting in a 2x2 area of pixels are affected and those fitting in 3X3 still have their centres punched out.

If you want to understand it better take a look at what I've written here:

Ah yes, sorry.

I was thinking of something someone else posted and it was incorrect. My apologies.

Greg.
