it's getting dimmer and dimmer every night as it moves away from earth this is a stack and add of 28 frames effectively for 10 seconds exposure, but with the noise being proportional to SQRT(28) of if I tracked a single 10 second photo. I can't see it at all with my own eyes anymore. not like Hale-Bopp back in the early 90's where you could read by it's shine! nearly anyway xP
