Finally had a clear night again. That took weeks!

All shot with Nikon D5300 on ISO200, unmodded, without dark, flat or bias.

Some of the basic operations in Siril: background exraction, photometric color calibration, removing green noise, histogram transformation, median filter and deconvolution.

In photoshop some masked processing, mostly levels, curves, vibrance and saturation and some star reduction
