Description

First night for color

Second night for luminance - Sky less good than first night but signal is here... Slight reduction in FWHM does finally not affect the overall quality of the image.

Unexpectedly the noise is reduced and details are sharpened... Even with few 13 shots for the luminance. This is promising for futur improvement with a better sky and far more data.

Description: Totally reviewed data with new Pix processes.
I am still thinking this is short of data and 8°C was bad for the sensor.
