Oh it's good, but there's rain right now behind the window. It's so frustrating,
because I had no clear sky last month and a half, and thus missed so many events,
and it looks like I'll miss this event too.

I haven't SLR camera or something like that; except Lumia 925, which camera
letting me manually set focus (to infinity too) and exposure from 1/2000
sec to 4 sec. I can set ISO manually too, but it looks like big ISO just increases
the noise, so instead it I playing with exposure time. I was really surprised
when camera cathed 6th mag. stars, but I seen maximum 4.5 mag. with unaided eye!
Think you will smile, but I've constructed the stand for Lumia using LEGO,
in which I can precisely control the angle at which to shoot the sky, and
also it's reduces shake and helps to shoot at long exposures.
The stand looks like that:

In my setup "stool, stand, Lumia" 6 months ago I've catched -8.5 mag. Iridium flare:
