Re: LT 的可保留相集 (海外編) -- Scorpius and its vicinity
20. Scorpius and its vicinity
One was stacked in PI while another stacked in DSS, darks calibrated only
Then the two stacked images were processed in both PI and PS with almost exact workflow.
No saturation and color balance were applied either in PI or PS after PCC applied in PI.
Taken with EF35mm F2 lens + 40Da in Coonabarabran in Australia in 2010 @F4
10x360s @iso800, unguided with Vixen GP mount
Then, if interested. image A or B,
1. which do you prefer to pick up?
2. which was stacked in DSS?
Larger image A Larger image B

Re: LT 的可保留相集 (海外編) -- Scorpius and its vicinity - ver3
Reprocessed again by aligning the RGB channels in HistrogramTransformation in PI after auto stretching (STF) applied.
Then final touch in PS by adjusting the brightness and contrast with Curve and Level
