| Comments: |
The picture is assembled with LRGB technique. The L-component is taken through C filter 31 min binned 1x1. The colour components are B, V and R (30, 30 and 42 min respectively) also binned 1x1. All individual exposures are calibrated with bias, dark and flat. Aligning, combining, sharpening, stretching, cropping and LRGB in MaximDL/CCD. Contrast and final retouch in Photoshop. |
