Description

Repost my IC342 processed previously and in recent times to show how processing affect the overall image.

The image was taken on Mt. Hehuan for my first time and it's my first long exposure work.

Although imaging plane was not quite perpendicular to optical axis caussing some tilt stars and misalignment of L/RGB data, the overall results are not too bad especially compare to old version work.
