Description

A 4 panel mosaic, each panel a HaRGB composite.

The Hydrogen alpha panels were created with narrowband extraction from OSC data, with the Optolong L-eXtreme Filter.
The RGB panels are basic OSC exposures with the Optolong L-Pro.

Stacking consisted of calibrating and stacking all frames per panel and per filter, and combing the panels into two mosaic sets.
All of the stacking, merging and color calibration was done with AstroPixelProcessor.

After combining the HaRGB integration, processing included BlurXTerminator, noise reduction, sharpening and color saturation.
