Gazing at clusters that are located many lightyears away gives us a profound reminder of our place in the Universe. If you make the switch from observing to drawing, you\u2019ll find that what you draw becomes an authentic learning experience. In this article, I\u2019ll show you how to capture the Beehive Cluster, M44, and bring it down to Earth by drawing it. The process of making this happen can be a real pleasure, as you try and reproduce this deep-sky object as clearly and accurately as possible on paper.<\/span><\/p>\n\n<h5 class=\"article-subhead\"><strong>Taking a new approach<\/strong><\/h5>\n\n<p class=\"article-full-body sans-serif\">When I began to draw deep-sky objects, the materials I found at my disposal were white paper and pencils. Although it was thrilling to look into nebulae and clusters with a pair of binoculars or a telescope, my initial efforts to record these targets were far from exact compared to what I saw. This wasn\u2019t because my efforts were inaccurate, but because space is black. Indeed, most of the observed objects were various tones of grey and white. I changed my approach to astronomical sketching, and using black paper was a real turning point. It opened up the possibility of using white gel pens for stars and soft pastels for nebulous material. You can experiment with different media and get familiar with how faint or bright each pen can be when you draw a star. The pen\u2019s size, plus how much you press on the paper, can be used to show different magnitudes. To do an excellent job of any drawing requires motivation. When you look at open clusters with a massive amount of stars, it can be overwhelming at first, so you need to find an initial starter shape from <span>which the rest of the drawing can grow.<\/span><\/p>\n\n<p class=\"article-full-body sans-serif\">On a cold wintry night, on 5 January, I noticed the Beehive Cluster was rising above a local hill, which provided an interesting aspect. M44 looked terrific against the top of the ridge, especially through my 15&#215;70 binoculars. It provided an opportunity for making a sketch, which I did from 19:15\u201320:00 UT.<\/p>\n\n<p class=\"article-full-body sans-serif\">I began the sketch by drawing the hill\u2019s profile in pencil on my preprepared circle. Next, I spent a few minutes looking at the shapes made by the stars that were nearest the hill\u2019s edge. It was noticeable how fast M44 was moving upwards. I added brighter stars first, followed by dimmer ones.<\/p>\n\n<p class=\"article-full-body sans-serif\">There is a triangular shape at the heart of M44, which looks like \u2018&gt;\u2019 \u2013 the mathematical symbol for \u2018greater than\u2019 \u2013 through binoculars. With five bright stars and a few dimmer ones, this shape makes a good starting point for a drawing. Next I added fainter stars, such as those below the triangle, as it rose up from the hill, where there were two smaller triangles. These patterns are helpful as guides to build up a drawing and to add more detail. Make sure you always write on the drawing the start and end time, in Universal Time (UT), and the instrument used for the observation. <\/p>\n\n<p class=\"article-full-body sans-serif\">The drawing was finished indoors by painting black gesso over the hill area to separate it from the night sky. Spray fixative was used (outside with good ventilation) to seal the drawing, and the final sketch now provides a permanent reminder of this cluster.<\/p>\n\n<section class=\"wp-block-uagb-section uagb-section__wrap uagb-section__background-color uagb-block-a86f5c55-521a-435f-b915-6f09f9140335 article-boxout\"><div class=\"uagb-section__overlay\"><\/div><div class=\"uagb-section__inner-wrap\">\n<h4 class=\"has-text-align-center article-subhead\"><strong>What you\u2019ll need <\/strong><\/h4>\n\n\n\n<p class=\"article-full-body sans-serif\">Binoculars, 10x50s or larger on a tripod, or any telescope; if you are using a telescope, its lowest power eyepiece is best.<\/p>\n\n\n\n<p class=\"article-full-body sans-serif\">A red headlight or a clip-on orange LED with a low setting; white gel pens with various size tips; colour gel pens.<\/p>\n\n\n\n<p class=\"article-full-body sans-serif\">A clipboard and A4 black card or strong paper; black pastel; a spray fixative; warm clothing and a good sturdy seat are useful too.<\/p>\n<\/div><\/section>\n\n<h4 class=\"has-text-align-center article-subhead\"><strong>Step by step<\/strong><\/h4>\n\n<h5 class=\"has-text-align-center\"><strong>Step 1<\/strong><\/h5>\n\n<div class=\"no-tts wp-block-image article-in-image photo\"><figure class=\"no-tts aligncenter is-resized\"><img loading=\"lazy\" src=\"https:\/\/dj9jqhxgw9833.cloudfront.net\/uploads\/sites\/77\/2022\/04\/2ec84541-61ff-43ce-b4a1-c0d4aecde011.jpg\" alt=\"\" class=\"no-tts wp-image-31079\" width=\"520\" height=\"301\" srcset=\"https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/04\/2ec84541-61ff-43ce-b4a1-c0d4aecde011.jpg 1039w, https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/04\/2ec84541-61ff-43ce-b4a1-c0d4aecde011-300x174.jpg 300w, https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/04\/2ec84541-61ff-43ce-b4a1-c0d4aecde011-1024x593.jpg 1024w, https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/04\/2ec84541-61ff-43ce-b4a1-c0d4aecde011-768x445.jpg 768w\" sizes=\"(max-width: 520px) 100vw, 520px\" \/><\/figure><\/div>\n\n<p class=\"has-text-align-center article-full-body sans-serif\">Set up your binoculars on a tripod or telescope at a suitable safe and dark site.
