Bits of LMC in Narrow Band

With the weather report predicting five nights clear in a row with some moon in Melbourne. Thought I would set up the Skywatcher 150mm F5 Achro.

Canon 5DH. Skywacher 150mm F5 with Hutech FR/FF so FL is 640mm and f/4.25. Astronomik 13nm HA and O3 NB filters.

Exposures 20x(2m, 4m and 8m) at 1600 ISO for both HA and O3.
Mapped Ha to red, O3 green to green and O3 blue to blue. All done in HDR.

The FR/FF spacing ring needs a tweak from standard to flatten the field better.
