Nikon 300mm f/4.5 ED IF

I thought i’d share with you some of my favourite Nikon lenses for astrophotography i’m using at the moment for taking images of Nebula and other deep sky objects. The first one i can recommend is the Nikon 300mm f/4.5 ED IF AI-S Nikkor (1978-1999) This is Nikon’s best manual focus 300mm ever. It’s very compact, not to heavy and gives great results and can be had for a few hundred pounds.

ED means it has Nikon’s magic glass for superb sharpness. IF means internal focus, meaning it focuses very smooth and the build is superb. For focusing on stars i find using a rubber band around the focus ring improved the accuracy of my focus and helped keep the focus nailed all night long.

Highly recommended!
