I would say it is Neptune John, my SNP came up with this 53' x 34' view for last night ~5 am - the bright star around 1 arc minute away is mag 8.4, the only brightish star in FOV - check the movement of neptune over coming nights to confirm (if its still clear that is) btw triton is mag 13.47 i dont think your digicam would pick that up in a single shot. Congrats nice capture mate - I'm impressed

EDIT: woops the first red dot near star is for last night, neptune in second position for tonight
