Severe Light Pollution and Ha Flaming Star

Azaiba, Muscat, Oman

At my home, with painfully high light pollution, Visual Limiting Magnitude 3.5, crying out for narrowand. A 7nm Ha filter served well. No white-light frames at all. Colorized in image processing software by adding white to brighter regions and embedding a dark blue-green background.

For other stuff peruse my primary website:

Hutech Canon T1i (500D),C14 Hyperstar at f1.9

other sizes: small medium large original auto
