Interesting bit of blue nebulosity there Tim.

Maybe a bit of star bloating and an unusual bit of star trailing. Do you use an IR filter or is there one in the imaging train? I check each sub with digital development set way high and if you check your subs you might find just one to eliminate that has star trailing - some mount settling issue maybe - bit of RA and DEC?

Or a big snake went past and bumped the tripod?

Puzzled, I am.

So was the snake.
