Took this a few nights back, 3x5mins ISO400, uhcs filter used in back of Berts 300mm f2.8 lens
This is a crop to the lower right edge as 253 is in centre of original umage globular 288 in a corner. This shows the incredible optical qualities of the flourite lens, stars pin sharp to the edge of the frame even though shot at f2.8.
Full res. crop here
