Landscape Sword of Orion

Sword of Orion · **2 Likes**

Trying out my newly acquired 200/4 lens on this classic astrophotography target, and I must say I'm very satisfied. It has amazingly flat image field for an 40 year old prime, and color aberration was minimal even though the photo was shot nearly wide open.

This photo is stacked and post-processed from a total of 1 hour's exposure at ISO 1600 on a K-5II.

Wow! Makes me want to have another try with the DA*300 f4. You've captured the Orion Nebula in the sword and the Horsehead Nebula as well! What length was each exposure and how did you track the target over an hour?

Each exposure is about 2 min. I'm using a skywatcher star adventurer EQ mount, which is enough for lenses of 300mm equivalent and below.

Thanks for the info! The equatorial mount is clearly critical.

Nice work getting the GON, Horsehead and flame nebulas in the same frame!
Nice processing too!
