This image is the first light trial of my new TS Photoline APO 115mm, f7, 800mm fl.
It is also an experiment with a higher dynamic range setting with short subs for the ASI1600M-C (Gain 105, Offset17, Temp -25C).
Image consists of just: (50x40sec Red, 53x40sec G, and 45x40sec B). No Lum added. Registered and stacked in DSS with Darks and Bias. Layer nd colour processing in Photoshop CC.
I will return to this target when the weather permits to build up the data.
