While waiting for Scorpio to rise took a set of images of Crux.
Details
Canon 5DH, 300mm F2.8L, Hutech LPR filter. Fridge at -14C.
Six sets of exposures from 5x15s at 200 ISO to 15x2min at 800 ISO.
ImagesPlus used for converting RAW to TIFF. Registar used for stacking each set and obtaining identically sized frames for producing a HDR image in
EasyHDR.
Just practicing for the really hard ones! The sky went foggy soon after so ruining the rest of the night.
I am still feeling my way but the HDR and judicious exposures seem to produce images with qualities that have never been seen before. At least in my experience.
