What made you choose this object?

I choose objects based on several criteria.

    1. The season, that is, the object is transiting (crossing the meridian) around the middle of the night (or middle of the darkest portion of the night  if the moon becomes an issue)
    2. It has interesting features and /or colors
    3. It is challenging. I like pushing the limits of my equipment and myself.

      The crescent nebula met all the criteria, and I especially love the “blue gel” that seems to be oozing out, which is Oxygen -ich gas, glowing from the energy of Wolf-Rayet star WR 136 (HD 192163).

The Harvest Moon, George Preoteasa

Your target:

The Harvest Moon, September 20, 2021

Where this photo was taken:

Eagle Rock, NJ

Equipment used:

Sony full frame camera with a Sigma telephoto lens 150-600mm with a 1.4x extender. The effective focal length is ~600mm.

What made you choose this object?

The target, if not obvious, was the moon and I chose it because it was photogenic against the Midtown skyline.

It began to show up in photos as more than a green dot in mid-November to those with large telescopes. While advertised as about magnitude 5 or less, the diffuse comet wasn’t really visible to the naked eye.
