Pleiades vs California (28-29/12/2016)
發表於 : 2017-01-03, 10:58To image the M45 & California is not difficult. But the Nikon AF 105mm/F2 DC is particularly difficult to be used in astrophotography. I used live-view to do focusing. When the spot size is smallest, there is red tint, chromatic aberration, around the stars. If the stars are white, perhaps reasonable white, the spot size is not the smallest. I need to juggle around between these two condition. This made the focusing particularly difficult.
