I last shot the Crescent about 12 years ago at the Golden State Star Party in Adin CA. Having a good clear night last Saturday. I decided to take advantage of the situation and revisit the nebula, however instead of using a telescope I went with a 300mm lens. I was amazed at how well the lens did. Nice small in focus stars with no bloating or any CA or fringing.
This was done using my guider hooked up to the L- Bracket on my camera.
