About this image

Collected 10 subframes at 5mins each in Ha then same again in OIII twice over as this image is a mosaic using two panes. Stacked the panes in Moravian camera software SIPS moving into Photoshop to stitch the two Ha and two OIII sections together. Afterwhich I used Maxim D/L4 to colour combine using the Ha,OIII,OIII palette,then back into Photoshop for final processing.
