If these three binoculars had approximately equivalent coatings and transmission the twilight factor advantage would be with the 10x50. The Swarovski SV 10x50 would have a twilight factor of 22.36 and the Swarovski 8x56 SLC would have a Twilight Factor of 21.17 and the Zeiss 8x54 HT would have a Twilight Factor of 20.78. I would bet you would make out more detail in low light with the 10x50.</p></blockquote><p></p>
