Taking advantage of some semi clear skies to the north I was trying to find M33 Pinwheel galaxy when a "star" approx magnitude of between 0 and +2 entered the bottom of my fov travelling vertically at some speed. I was able to track moving the scope every 3-4 seconds as this was all it took for the "star" to travel from top to bottom whizzing past all the other stars in the area. I was expecting it to burn out at any point in time but it didn't! It was travelling much slower than the shooting stars I've seen and continued along at consistent brilliancy until I dared to lift my head to see if i could track it by eye, but lost it. I estimate that I tracked from the rough area of M33 approx, to +70 alt which took all of 15 - 20 secs. The time of the sighting was 21.40. Can anyone explain what it might have been please?
