Description

Here's an extreme wide angle from my urban backyard from December 2021.  I started this imaging session while my wide field composition was still low in the sky that included a backyard tree. It's a challenge to shoot wide angle  without any instrusions (trees, buildings, antennas etc). I wanted to integrate as many frames as possible. I was struggling to pixel reject that part of the frame. So instead of fighting it, I took one frame, debayered it, color corrected and layered on top using PS. Next time I'll snap a regularly (not long) exposed frame of a sharper foreground tree element for a nicer final composition.
