I have this idea about going deep RGB on NGC7000, but not shooting full spectrum red at all. Shoot Ha for the red channel and standard green\/blue all binned 2&#215;2 and then shoot a luminance set binned 1&#215;1 and see how that turns out. I think I could pull it off in one night because of the lens speed, but it&#8217;s a big effort to pack up and drive an hour+ each way a second night in a row.<\/span><\/p>\n<p><span style=\"color: #993300;\">Disappointed that<span class=\"text_exposed_show\"> I didn&#8217;t capture what I set out to last night, I was cold and done with time to wait while another imager was finishing his run of 15 minute subs, so I set up a short series of 5 minute luminance subs while we waited for our window to tear down. I registered those this morning and manually integrated them, then took an already integrated OSC data set from October of 2014 that I shot with a stock DSLR and converted both from linear to non-linear and did a simple LRGB combination folding the new lum data into the old color data. I didn&#8217;t do a color calibration or anything, so I&#8217;m certain there are far better ways to do this&#8230; I was just messing around and didn&#8217;t want to waste the data. It didn&#8217;t turn out half bad! Once I develop my post-processing Fu some more, I would like to have a catalog of &#8220;good&#8221; data that I can keep adding to over time.<\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<figure id=\"attachment_230\" aria-describedby=\"caption-attachment-230\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/13thstone.com\/blog\/wp-content\/uploads\/2015\/09\/m45.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-230\" src=\"http:\/\/13thstone.com\/blog\/wp-content\/uploads\/2015\/09\/m45-300x254.jpg\" alt=\"Messier 45 \u2013 Pleiades\" width=\"300\" height=\"254\" srcset=\"https:\/\/13thstone.com\/blog\/wp-content\/uploads\/2015\/09\/m45-300x254.jpg 300w, https:\/\/13thstone.com\/blog\/wp-content\/uploads\/2015\/09\/m45-1024x867.jpg 1024w, https:\/\/13thstone.com\/blog\/wp-content\/uploads\/2015\/09\/m45.jpg 1200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-230\" class=\"wp-caption-text\">Messier 45 \u2013 Pleiades<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;m on the fence about heading back out tonight for some wide-field imaging.
