Description

Both images were obtained from 29 images of 300 seconds each, stacked with Pixinsight, with 20 darks, 100 bias and 100 flats, in a Bortle 8 sky, using a William Optics GT 71/420 telescope and ASI 2600 MC camera.

The image on the left was obtained with the Optolong L-Extreme filter and the image on the right with the Optolong L-Pro filter. Both were processed with DBE, Background Neutralization, Histogram Transformation, Colour Calibration, Curves Transformation, ACDNR and post-processed with Capture-One. 

The L-Pro image was obtained on 29/12/2021 and the L-Extreme image on 19/02/2022, with the nebula at 71° and 53° declination, respectively.

The results are conclusive.
