Integration per panel: L- 8 x 180s R- 8 x 180s G- 8 x 180s B- 8 x 180s Darks, Bias, & Flats acquired for each panel
Acquisition: Captured with the use of Sequence Generator Pro by Main Sequence Software. Edited and calibrated bin Pixinsight Astro Imaging Software. Export & Levels in Adobe Photoshop. Data captured over the course of three years, traveling remotely to image from dark sites in TN, GA, and TX. 2019 data captured in the Marathon Remote Imaging Observatory (MaRIO) in Marathon, TX.
Workflow: Calibration in BPP with flats, darks, bias, and light frames-per scope (Batch Pre Processing) Integration with star alignment outside of BPP with the Star Alignment Tool Processing with LRGB combination and photometric Color calibration applied per pane Histogram transformation, SCNR and Curves to match each panel. Assembled by image solving per panel Mosaic by coordinates Gradient Merge Mosaic to ensure proper panel alignment and solving Levels and exporting in Photoshop
