Interstellar by Matt Walker

It’s been a while since I’ve posted a Milky Way shot on Flickr, so here is one from our recent trip to the PNW. This place is called Secret Beach in the Samuel H Boardman area. It’s no secret though, and it has been heavily photographed in recent time. It’s a really cool beach with tons of sea stacks. We shot into blue hour, and captured a pretty decent sunrise too. Thanks for looking!

Milky Airglow, by JohanEickmeyer

The night sky as it rises over Crater Lake. This night had a particularly strong airglow effect that the other nights didn’t have over the week-long stay. You can clearly see the green airglow that sort of looks like a faint Northern Lights.It’s pretty amazing how bright the sky can be at night in this area. If you have never seen it before, make sure to do it! Best when visited during no moonlight. This image is exposure blended, focus stacked, and panorama stitched. This can get really messy pretty quick with something like the Milky Way moving so much from image to image. Required a lot of work to get a clean result. :) Thanks for looking! -Johan
