I think that last night I captured a meteor in a subframe of some more NGC's I was taking in the LMC.
The subframe is Ha, 15 minutes, taken at about 0140hrs this morning. There are numerous Gamma ray hits. The subexposure has been calibrated. I was going to add all the subs together, but my routine removes things like this.
Anyway, other possibilities always considered, but this one does look like a meteor.
