I shot some sub-images with my modified Canon T3 of the Running Man the other night and added that to the Orion Nebula test image I took recently and made a composite mosaic image of the two. I also shot some short subs (9) of the Orion Nebula core and made a HDR image from them and then composited that in to replace the burnt out core that I had previously.
So, the breakdown is 36×180 sec @ ISO 3200 for the bottom half, 30×180 sec @ ISO 400 for the Running Man and 9 sub-images from 5 to 30 seconds @ ISO 1600 merged into a HDR image in IRIS and then divided into 3 layers of various opacity settings and masking to blend in for the core area.
The ISO 3200 images had 2 LP filters – a Deep Sky filter and an IDAS-LPS. The ISO 400 images and the core images were only shot with an IDAS-LPS. A GSO 8″ F/4 Newtonian with a GSO 2″ Coma Corrector was the imaging scope.
