I uploaded this photo as a self-discipline.
I was running to Tama river by bicycle tonight. But as I forgot to wear my gloves, I directly felt the chilly air. My fingers were so numbed with cold that I couldn't spare enough time to check whether I managed to set focus on the stars.
As a result, I realized in front of my PC screen that this photo is a bit out of focus. It will be colder and colder as the days go by. I must do all sorts of preparations to get the best image in front of me.
