With a relatively wide angle lens, tracking errors become insignificant.<\/p>\n<p>With the center of the Milky Way high overhead it made an obvious first target to test this wide-field setup.  The results are quite nice, a series of one minute exposures reveal the star clouds in fine detail.  The camera for this run was the Canon 60D, as the 20Da was <a href=\"https:\/\/darkerview.com\/wordpress\/?p=4336\">shooting the Lagoon<\/a> at the time.  I need to swap places and try the shot again with the 20Da to see what the H&alpha; sensitivity reveals, capturing more of the nebulae that is mingled with the stars.<\/p>\n<p>The lens was an older Nikon 50mm f\/1.8 stopped down to f\/2.8, nice round star images right into the corners of the frame.  Yes, a Nikon lens mounted to a Canon camera, <a href=\"http:\/\/diglloyd.com\/articles\/ask\/lenses-LensAdapters.html\" target=\"_blank\">you can do that<\/a>.  A very nice lens, I will be using it again for this work.<\/p>\n<figure id=\"attachment_4436\" aria-describedby=\"caption-attachment-4436\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/darkerview.com\/wordpress\/?attachment_id=4436\" rel=\"attachment wp-att-4436\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/darkerview.com\/wordpress\/wp-content\/uploads\/2012\/05\/GalacticCenter20120520.jpg\" alt=\"Galactic Center\" title=\"Galactic Center\" width=\"600\" height=\"900\" class=\"size-full wp-image-4436\" srcset=\"https:\/\/darkerview.com\/wordpress\/wp-content\/uploads\/2012\/05\/GalacticCenter20120520.jpg 600w, https:\/\/darkerview.com\/wordpress\/wp-content\/uploads\/2012\/05\/GalacticCenter20120520-400x600.jpg 400w\" sizes=\"(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 984px) 61vw, (max-width: 1362px) 45vw, 600px\" \/><\/a><figcaption id=\"caption-attachment-4436\" class=\"wp-caption-text\">The galactic center region on the Sagittarius-Scorpius border<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The last time out I fitted a camera ball mount to the counterweight shaft of the Losmandy mount.
