Description

To improve colors and details, I have used an hybrid color palette composed by narrowband, red and blue data that shows

together primary and complementary colors along a continuum.

125 raw H-alpha images of 10 minutes each unbinned

129 raw OIII images of 10 minutes each unbinned

132 raw SII images of 10 minutes each unbinned

91 raw Green images of 1 minute each binning 2x2

90 raw Green images of 1 minute each binning 2x2

89 raw Blue images of 1 minute each binning 2x2

Total 656 raw files

68h50 total exposure from 08/22/2016, 08/23/2016, 08/24/2016, 08/25/2016, 08/26/2016, 09/01/2016, 09/02/2016, 09/03/2016, 09/04/2016, 09/06/2016, 09/07/2016, 09/08/2016, 09/09/2016, and 09/10/2016

A full resolution of 8332x5829 pixels for a total of 48MPixels

FOV 4.8° x 3.4°

50 bias + 50 dark + 50 flats for calibration in CCDStack
