Description

Hi,

yesterday was the first somewhat clear night in a long time. So I decided to get my gear out and do some imaging of M101 which was just in the right spot for an all-night observation. This image is the result of roughly 5h of data.

Processing (PixInsight):

- Calibration (200 bias, 25 darks)

- Debayer, Superpixel

- Registration

- Drizzle, 2x, 0.75 drop shrink

- Linear Fit

- Channelmatch

- Dynamic Background Extraction

- Deconvolution

- ATWT

- Histogram Transformation

- Local Histogram Transformation

- Histogram Transformation

- Curves Transformation
