The Seagull Nebula in Monoceros
Emission and Reflection nebulosities
Uploaded 3/28/26

This deep image uses the sharpest camera lens I have ever encountered, the Zeiss Milvus 135mm f/2. Wide open its produces pinpoints across the entire field. If you go deep enough, you can see that the Seagull nebula here has huge extended wings running all the way to the top and bottom edges of this field. These are virtually unknown in other amateur images. Even the Wolf-Rayet bubble at the top NGC2359 seems to have extended insect like wings extending east and west. Ive tried many times in the past six months to nail this composition, and finally got it!
