Church Bay’s Cosmic Cathedral

The Milky Way as seen from just above Church Bay, at Weaver Point, in Co. Cork. This was last night, a few minutes after the moon had set. Unfortunately, the centre of the galaxy was hidden behind a bank of clouds at the horizon. The forecast said there would be about 30% cloud, but thankfully it mostly didn’t cover most of the galaxy.

The best time to see the centre of the Milky Way again from Ireland will be in March 2026. However, you’ll still be able to shoot the less bright celestial arms once the moon has set for a good few weeks, probably.

I recommend using Sun Surveyor to plan a Milky Way shot. Photopills is good too, but the street view integration in Sun Surveyor is difficult to beat.

Celestial Circles

The sun was particularly active last weekend, promising spectacular aurora with KP values of over 7. Unfortunately, the expected nighttime display failed to materialise. Instead, I swung my camera around and took 10 30-second exposures of the night sky, with the trees of a nearby road.

After combining them in Photoshop this is what you get. Not bad for 300 seconds.

Star trails form circular patterns around the celestial pole due to the Earth’s rotation, and in the Northern Hemisphere, these circles are centred on Polaris, the North Star, which barely moves at all in the sky. I wasn’t sure where Polaris was, but it looks like it’s just off the photo.
