Love me some Ophiuchis. What a treat for the eyes. Or a fever dream if overcooked... Please tell me how you feel about this rendition?! 😀 The damned thing only goes as high as 20 degrees in the aky out here.
Anyway, this is a 2 panel mosaic taken from Bortle 4.5 sky in Eastern Ontario, Canada. One panel is around 8h of acquisition, and another about 3h. I used a Sharpstar 61 III Apochromatic refractor with 0.75 reducer and ToupTek 2600C color camera with IMX571 sensor.
Acquired over 6 nights in total this year.
Stacked panels separately in Pixinsight. Did star correction, ADBE, background neutralization, then mosaic by coordinates, photometric mosaic, plate solved, SPCC, separated stars out, multiscale adaptive stretch, a lot of GHS and curves, dark structure enhance, stretched stars with SetiAstro star stretch. Combined in Affinity Photo 2 layers based editor, some final adjustments there and voila!
