very well presented image, have had a look at your website in the past and you have done some lovely and varied work. Theres a huge number of galaxies there, ive never gone more than 3 hrs must have a crack at going longer just to see how much difference it makes. Always enjoy a look at your work
no-one else seems to have asked so i will- why the extra diffraction spike ? (the softer vertical one)
