I took these pictures on 1/4/2017 with different speed settings - 1/13 and 1/20 with exact A and ISO settings. The one on the left has no star/cross along the edge but the one on the right has a lot. I am wondering if it was the speed or something else. Please help and comments. Thanks.
What camera and lens? Speed too slow and ISO too high. Here's one from 1/1/2017 at ISO 200, 1/100, f/5.6:
