The nebula is visible as a hazy patch in a small telescope, while a
larger aperture will show a pair of dark nebulae designated Barnard 1

constellation Orion. The nebula is located just to the south of the
star Alnitak, which is farthest east on Orion's Belt, and is part of the
much larger Orion Molecular Cloud Complex. The nebula was first
recorded in 1888 by Scottish astronomer Williamina Fleming on
photographic plate B2312 taken at the Harvard College Observatory. The
Horsehead Nebula is approximately 1500 light years from Earth. It is one
of the most identifiable nebulae because of the shape of its swirling
cloud of dark dust and gases, which bears some resemblance to a horse's
head when viewed from Earth.</p>Andreas72http://www.blogger.com/profile/13517036244541303328noreply@blogger.com0tag:blogger.com,1999:blog-2305913782794351497.post-58828258088503529902023-01-23T16:53:00.005+02:002023-10-29T20:08:47.131+02:00NGC 7380 Wizard nebula_SHO<p></p><p></p><p></p><p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEihyphenhyphenG9mCWCyp-UP8w1FFK_ywVKHJWulqiK4VhUJpLZwzCRMPgpS4rQimX5Lm8OKTqPFXUeju4qmu8o8XTjzMV3rmImso52Z23XaIbyce-Rpi-Hx0854fgLzpcx2pEo4KiHLwx6KZFlk6qSc9Ns70QFercBx7koEP-VguT3FiSh-sfg41AoseJ6X0UZtNIg/s2629/SHO_NGC7380_Wizard_v2.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2089" data-original-width="2629" height="508" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEihyphenhyphenG9mCWCyp-UP8w1FFK_ywVKHJWulqiK4VhUJpLZwzCRMPgpS4rQimX5Lm8OKTqPFXUeju4qmu8o8XTjzMV3rmImso52Z23XaIbyce-Rpi-Hx0854fgLzpcx2pEo4KiHLwx6KZFlk6qSc9Ns70QFercBx7koEP-VguT3FiSh-sfg41AoseJ6X0UZtNIg/w640-h508/SHO_NGC7380_Wizard_v2.png" width="640" /></a></div><br /><p></p><p></p><p></p><p></p><p></p><div style="text-align: left;"><b>Telescope :</b> SW Esprit 100ED<br /></div>

It is part of a larger star forming region that also contains the Flaming Star Nebula.<br />The gas structures in this picture are lit by the radiation from the open star cluster NGC1893 that lies in the center of the nebula. <br />This star cluster is about 4 million years old, but in astronomical terms it is still very young, with hot, massive stars. <br />At the top-left of the star cluster two more dense structures are visible. These are similar to the famous Pillar of Creation and they are composed of dust and gas leftover from the formation <br />of the star cluster and are very likely to give birth to more stars in the future. As can be seen in the picture, these structures <br />point away from the center of the nebula. This is because of the stellar winds and radiation pressure from the stars in NGC 1893. <br />Due to these structure's shape, the nebula is also called the Tadpoles Nebula.</span></span></b></span></span></div><p></p><p></p>Andreas72http://www.blogger.com/profile/13517036244541303328noreply@blogger.com0Γραμματικό 190 07, Ελλάδα38.2031194 23.96321949.892885563821153 -11.1930306 66.513353236178844 59.1194694tag:blogger.com,1999:blog-2305913782794351497.post-45742526948498130292021-12-08T20:57:00.000+02:002021-12-08T20:57:08.164+02:00IC 410 and the Tadpoles in Ha-First Light with SW Esprit 100ED<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgilNj9MRzMvpADpOW3hKXdnteO0E5PbqnXQWX5UgQXa2kl0jVTxKrOmoR03zlo7AI1SJTrfqGo1Jd6QrpSZMaAb9phBRMBSx3H606XClsvJBuC_M_yWYyOu_Ydb_IkRVSn3idYKs6Cq6pQO_Xy3fiXWi7RJwnkUWIq9DiT3ie9D4Vi10l3w3AMdd6v=s2048" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1638" data-original-width="2048" height="512" src="https://blogger.googleusercontent.com/img/a/AVvXsEgilNj9MRzMvpADpOW3hKXdnteO0E5PbqnXQWX5UgQXa2kl0jVTxKrOmoR03zlo7AI1SJTrfqGo1Jd6QrpSZMaAb9phBRMBSx3H606XClsvJBuC_M_yWYyOu_Ydb_IkRVSn3idYKs6Cq6pQO_Xy3fiXWi7RJwnkUWIq9DiT3ie9D4Vi10l3w3AMdd6v=w640-h512" width="640" /></a></div><p></p><p style="text-align: center;">IC 410 In Ha(Astrodon 5nm)</p><div style="text-align: left;"><b>Telescope :</b> SW Esprit 100ED<br /></div>

during an expedition to the Cape of Good Hope between 1751 and 1753. He
catalogued it as the second of the "Nebulae of the First Class",
"Nebulosities not accompanied by any star visible in the telescope of
two feet". It was described as a diffuse nebula 20' across.<a href="https://en.wikipedia.org/wiki/Johann_Elert_Bode" title="Johann Elert Bode">Johann Bode</a> included the Tarantula in his 1801 <i>Uranographia</i> star atlas and listed it in the accompanying <i>Allgemeine Beschreibung und Nachweisung der Gestirne</i>
catalogue as number 30 in the constellation "Xiphias or Dorado".
Instead of being given a stellar magnitude, it was noted to be nebulous.The name Tarantula Nebula arose the mid 20th century from the appearance in deep photographic exposures.30 Doradus has often been treated as the designation of a star, or of the central star cluster <a href="https://en.wikipedia.org/wiki/NGC_2070" title="NGC 2070">NGC 2070</a>, but is now generally treated as referring to the whole nebula area of the Tarantula Nebula.</p><div style="text-align: left;"><b>Telescope :</b> ASA 500N (19.6 inches) f\3.8<span></span></div>
