This is a wonderful region to explore with binoculars or a small telescope. Visually the nebula shows a soft gray and displays a wealth of fine detail. This is also a very rewarding region to photograph and even short exposures show a range of beautiful colors. The red of the Great Nebula is the emission of hydrogen set aglow by hot young stars within the nebula while the smoky blue\/gray is starlight reflecting off of interstellar dust. The dark lanes are veils of dust in the foreground.<\/p>\n<p><span style=\"font-family: Times New Roman, serif;\">This is the first of 14 images taken with my ASI Air Plus while using it along with my wide field 8\u201d LX200GPS for remote, camera-assisted observing. The scope was fitted with a Celestron 0.63x focal reducer\/field flattener, giving a focal ratio of f\/4. The camera was an uncooled ASI 294MC fitted with a 2\u201d nosepiece giving the 105mm backspacing from the focal reducer and holding an Orion Imaging Skyglow Filter that was serving as an IR cut filter. This system was configured primarily for wireless remote observing using Sky Safari via SkyFi to control the telescope and the preview mode of the ASI Air Plus to observe through the scope. The Live Stacking mode was also very effective, but for my purposes the Preview mode worked well. To make a record of interesting objects I used the ASI Air Plus to grab 32x15sec subs for later processing.<\/span><\/p>\n<p><span style=\"font-family: Times New Roman, serif;\">The Sword of Orion is currently well-placed <\/span><span style=\"font-family: Times New Roman, serif;\">rising in the east as<\/span><span style=\"font-family: Times New Roman, serif;\"> the sky darkens.<\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>Telescope: 8\u201d Meade Wide Field LX200GPS @ f\/4, Altaz mode Camera: ZWO ASI 294MC (uncooled) Filter: Orion Imaging Skyglow Filter Guide scope: None Exposure: 32x15sec, Gain 120, binned 2&#215;2, saved as TIFF Darks: None Flats: Synthetic Average Light Pollution: Red zone, Bortle 8, poor transparency Lensed Sky Quality Meter: 18.4 White Balance: Nebulosity Automatic Software: [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"nf_dc_page":"","pgc_sgb_lightbox_settings":"","_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[14,15],"tags":[],"class_list":["post-1819","post","type-post","status-publish","format-standard","hentry","category-forums-beginner-imaging","category-forums-deepsky-imaging","entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 -
