Technical Information:
LRGB: 510:165:180:210 (That's almost 18 hours of exposure time; luminance, red and green images were all fifteen minute unbinned images; blue were twenty minute unbinned images).
Equipment: RC Optical Systems 14.5 inch Ritchey-Chretien carbon fiber truss telescope, with ion-milled optics and RCOS field flattener, at about f/9, and an SBIG STX-16803 with
internal filter wheel (SBIG filter set), guided by an SBIG AO-X, all riding on a Bisque Paramount ME German Equatorial Mount.
Image Acquisition/Camera Control: Maxim DL, controlled with ACP Expert/Scheduler, working in concert with TheSky X.
Processing: All images calibrated (darks, bias and sky flats), aligned, and combined in Pixinsight. Color combine in Pixinsight. Some finish work (background neutralization,
color calibration, gradient removal, deconvolution, HDR multiscale transform, multiscale linear transform) done in Pixinsight; some finish work (Neat Image noise reduction, Smart Sharpening, LRGB
combination, contrast and saturation adjustment) was done in Photoshop CC.
Location: Data acquired remotely from Sierra Remote Observatories, Auberry, California, USA.
Date: Images taken on many nights in July and August of 2020. Image posted August 18, 2020.
Date: Image scale of full-resolution image: 0.56 arcseconds per pixel.
Seeing: Generally very good, with calibrated luminance images varying from 1.6 to 2.0 arcsecond FWHM
CCD Chip temperature: -25C
