Bit of a mystery

[raymo]

I took a 10sec sub of 3132; no sign of the centre star; tried 15 secs,
absolutely no sign, even with increasing mag. 20 secs, it's like a
searchlight; how can that be? All at ISO 6400 through an 8" scope.
I bought my first scope 59 yrs ago, and I've never seen anything like it.

Post the 3 pics Ray, without processing if you can. The brighter of the embedded stars is magnitude 10. Perhaps you need 20 secs to cross that threshold.

Hi Kevin, I'm heading up to the big smoke for the birth of my
grandchild, and probably won't get a chance until I get back in
about 8 days.

No worries.
