IC 2177 - Seagull Nebula

Introduction | Map | My Own Photos | My Own Observations | References

On this page I collect my observations of the galactic nebula IC 2177 (Seagull Nebula) in the constellation Monoceros.

Introduction

The galactic nebula IC 2177 (Seagull Nebula) in the constellation Monoceros is, according to Stoyan, very large and very faint. Nearby are the open star clusters NGC 2335 and NGC 2343. A little further away (to the North), but still close, is the open star cluster M 50, which can be observed together with IC 2177 in a Vespera mosaic. Still a little bit farther away (to the East), there is NGC 2359 (Thor's Helmet).

My Own Observations

Observations February 2020

February 17, 2020 (Mühlhausen/Kraichgau: eVscope): IC 2177 photographed in the new rectangular format without overlay, too large

Observations February 2023

February 12, 2023 (Mühlhausen/Kraichgau: Vespera): IC 2177 photographed (1) as a mosaic together with M 50, (2) directly (no mosaic), and (3) as a small mosaic to get a better framing.

Observations January 2024

January 29, 2024 (Mühlhausen/Kraichgau: Vespera): IC 2177 photographed as a small mosaic (2 turns); with NGC 2343 and NGC 2335; NGC 2177 very faint
