Friends,
Last night, a colleague was photographing the BL Tel field. Today when I examined the photo I noted a strange mark of a star (?) near Hip 93624. It seems me that is not a false pixel....
I estimated its mag between 9 and 10.

Very hard to tell.
I took an image of the region on 3/12 and have compared them. Unfortunately it is off the edge of my field so no use. The 101 comp star is barely visible in your image so it is brighter than that.
I wonder if it is just a cosmic ray hit. They can appear stellar if they are coming towards the sensor rather than across it. You would need a follow up image to confirm it.
My image is attached to show the 101 star.

Hi,
Thanks for your interest.
Maybe the mark (?) that appears is a photographic defect..
As I received several photos (around of 10) of this area (of this same person) and this mark does not appear in the other images, I decided to inform the fact only for register.
Cheers,
Carlos
