Description

Equipment

- Nikon D3300 (unmodified)

- Samyang 135mm f2 @ f2

- Skywatcher Star Adventurer Pro Pack

- no-name tripod

Acquisition

- 93 lights x 120 s = 3 h 6 min total exposure time

- no dark, flat, bias frames

- no filters

- ISO 200

- Bortle 4 zone

Processing

-> lights stacked in DSS

-> median kappa sigma clipping method

-> unmodified TIF opened in PixInsight

-> STF stretch

-> dynamic background extraction

-> background neutralization

-> color calibration

-> use of starnet++ to separate background from stars

-> arcsin strectch and local histogram equalization for background

-> individual histogram/curves transformation & SCNR (green) for stars and background

-> pixel math to recombine stars and background

-> ACDNR

-> final histogram/curves transformation

-> dynamic crop

-> resample 50%

-> saved as jpg

Description: For the new revision, I applied a "Local Histogram Equalization" step to the background only and increased the saturation of IC1396 a bit by a masked "Curves Transformation".

In my opinion, the image now looks a bit more vivid and three-dimensional compared to the original version. What do you think? Which one do you prefer?
