Milky Way against a bright moon

Just led my first full moon astrophotography expedition to Mount Bromo, one of the active volcanoes in Indonesia. It would have been easier to unveil the Milky Way against the bright moon on our first night there, but the sky was cloudy and we could only do this on our last night, which was more challenging as the bright moon was located nearer to the Milky Way’s galactic center.

The moon and Saturn made a close approach on May 6, passing just within 2° of each other, at around 35° above horizon at 5.30am (GMT +7). It was a cold night, and also when the Eta Aquarid meteor shower peaked. The large and bright waning gibbous moon, with its illumination at 97%, managed to obscure both the Eta Aquarid meteor shower and the spectacular Milky Way. Although I was able to see a few faint Eta Aquarid meteors on that night, I was unable to see the Milky Way with my unaided eye because the bright moon was so close!

Nonetheless, using the method that I have shared in this tutorial, I managed to unveil the Milky Way that’s obscured by the moon.

So it’s still possible to unveil the Milky Way against a large and bright moon! Give it a try.

Justin pointed out that the circular feature in the photo – on the lower left side – was not a real object in the sky over Mount Bromo. It’s an internal reflection from his camera, known as a lens flare, often seen (although usually not so beautifully!) in photos of bright objects like the sun and moon.

Thank you, Justin!
