Pleiades vs California (28-29/12/2016)

To 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.

照片很好,你進入高產期了。

那些星塵,特別是M45週邊的,應還可拍深一點。

Not really. Just because I have a holiday. I have equipment & skills, but no time.... I miss Tibet... With present equipment & skills, I can do better than before....
About the M45, there was bad guy around, cloud, when I wanted to image longer!
