This is because the plane of Earth\u2019s orbit (the ecliptic) makes a steep angle with the western horizon after sunset. The Moon\u2019s orbit is inclined to the ecliptic by 5\u00b0, meaning the Moon never wanders too far from the ecliptic\u2019s position in the sky. As a consequence, at this time of the year, the earlier phases of the Moon are presented at their best.<\/p>\n\n<p class=\"article-full-body sans-serif\">At the same time, the constellation of Taurus, the Bull, is positioned above the western horizon in the early evening sky, which presents us with an opportunity to capture the waxing crescent Moon with that most beautiful of star clusters, the Pleiades or M45.<\/p>\n\n<p class=\"article-full-body sans-serif\">Also known as the Seven Sisters, the Pleiades sits 4.2\u02da north of the ecliptic. This means that it lies within the Moon\u2019s corridor of motion across the sky and, at certain times, it\u2019s possible to see the Moon pass in front of the cluster stars. This is not the case currently, with the Moon appearing to pass below the cluster, but this can be a beautiful scene to capture too. In this article we will show you how to do this.<\/p>\n\n<p class=\"article-full-body sans-serif\">The months of February, March and April are optimal for a shot of the waxing crescent Moon and the Pleiades. Any earlier and the Moon\u2019s phase will be too great \u2013 its glare burning out the cluster\u2019s delicate stars; any later and the Pleiades will be doing battle with the evening twilight and their impact will be lost. There\u2019s a chance to capture both objects on the evenings of 7\u20139 March, with the smallest separation<span> occurring on 8 March. There\u2019s another chance on 4 and 5 April, when the Moon\u2019s crescent will be thinner and better matched to the cluster.<\/span><\/p>\n\n<p class=\"article-full-body sans-serif\">You can capture the Moon and the Pleiades with different types of camera, but for the best results consider using a device with good manual control, such as a DSLR camera or MILC (mirrorless interchangeable-lens camera).<\/p>\n\n<p class=\"article-full-body sans-serif\">A good choice of field of view can make or break a photograph like this. As the sky darkens, both objects will get closer to the western horizon. In March there\u2019s a fair amount of time between the sky getting properly dark and the Moon and Pleiades setting, while in April there\u2019s a bit less time. If there\u2019s something interesting in the foreground, consider using it in the shot. For this you\u2019ll need a field of view that can contain both objects and sufficient foreground horizon to prevent the image appearing cramped.<\/p>\n\n<p class=\"article-full-body sans-serif\">The Pleiades is a deep-sky object that typically requires a multi-second exposure to capture well, while the Moon is a bright, extended Solar System object that will overexpose using longer exposures. This puzzle may seem impossible to solve, but with a bit of creativity you can produce some amazing results. Also, if clouds are present, you could use them to introduce some extra detail into the image.<\/p>\n\n<p class=\"has-text-align-center article-full-body sans-serif\"><strong>Equipment: a DSLR camera or MILC (mirrorless interchangeable-lens camera)<\/strong><\/p>\n\n<hr class=\"no-tts wp-block-separator is-style-wide\"\/>\n\n<h4 class=\"has-text-align-center article-subhead\"><strong>Step by step<\/strong><\/h4>\n\n<h5 class=\"has-text-align-center article-subhead\"><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\/02\/80a945e5-50cb-47aa-8b1a-50de49f6f494.jpg\" alt=\"\" class=\"no-tts wp-image-29110\" width=\"520\" height=\"336\" srcset=\"https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/02\/80a945e5-50cb-47aa-8b1a-50de49f6f494.jpg 1040w, https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/02\/80a945e5-50cb-47aa-8b1a-50de49f6f494-300x194.jpg 300w, https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/02\/80a945e5-50cb-47aa-8b1a-50de49f6f494-1024x662.jpg 1024w, https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/02\/80a945e5-50cb-47aa-8b1a-50de49f6f494-768x496.jpg 768w\" sizes=\"(max-width: 520px) 100vw, 520px\" \/><\/figure><\/div>\n\n<p class=\"has-text-align-center article-full-body sans-serif\">Work out the field of view required to capture the Moon and Pleiades when the sky is clear.
