I tried some Ha imaging from my suburban backyard last night - a pretty good night in Adelaide with steady skies.
Used my new variable brightness lightbox for the first time for the flats - made by Peter Miller and highly recommended. Also the first time I've used flat/darks in my calibrating. The flats ended up being 11 secs long so I figured they needed darks. This is my first Tarantula image.
