Barnard 33 (B 33) - Horse Head Nebula

Introduction | Map | My Best Own Photos | My Own Observations | References || Appendix: My Own Photos

On this page I collect my observations of the dark nebula B 33, called Horse Head Nebula, in the constellation Orion.

Introduction

According to the German Wikipedia, the Horse Head Nebula B 33 is a 3 light years large part of a dark cloud in the constellation Orion, which stands out in front of the red glowing emission nebula IC 434 with a silhouette similar to a horse head. The nebula is about 1,500 light years away from earth and therefore appears a quarter of the size of the earth's moon.

With a wider field of view of the telescope, you can observe the Horsehead Nebula B 33 together with the Flame Nebula NGC 2024. On some photos also the emission and reflection nebula NGC 2023 can be seen next to B 33.

My Own Observations

Observations January to March 2020

January 28, 2020 (Mühlhausen/Kraichgau: eVscope): B 33 photographed, very hard to find even in post-processing
February 16, 2020 (Mühlhausen/Kraichgau: eVscope): B 33 photographed and with difficulty to see after processing the photos
February 24, 2020 (Mühlhausen/Kraichgau: eVscope): B 33 photographed and already recognized while observing (fainter in eyepiece); good to see after editing the photos
March 13 and 25, 2020 (Mühlhausen/Kraichgau: eVscope): B 33 photographed; in part longer exposed (less noise, but somewhat different colors)

Observations November 2020

November 17, 2020 (Mühlhausen/Kraichgau: eVscope): B 33 photographed in the new rectangular format without overlay; in part longer exposed

Observations February to April 2021

February 20, 2021 (Mühlhausen/Kraichgau: eVscope): B 33 photographed (r.f., n.o.); longer exposed
March 7, 2021 (Mühlhausen/Kraichgau: eVscope): B 33 photographed (r.f., n.o.); longer exposed; photos discarded, because of misfocus
March 8, 2021 (Mühlhausen/Kraichgau: eVscope): B 33 photographed (r.f., n.o.); longer exposed
March 25, 2021 (Mühlhausen/Kraichgau: PS 72/432 with Atik Infinity): B 33 photographed together with NGC 2024 (Flame Nebula)
April 3, 2021 (Mühlhausen/Kraichgau: PS 72/432 with Atik Infinity): B 33 photographed together with NGC 2024 (Flame Nebula)

Observations January 2022
