Description

Cette image est une reprise du traitement de M101 ( https://www.astrobin.com/pgec6z/ ) qui utilisait uniquement des images prises avec un filtre IDAS LPS-D2.
Pour cette image, j'ai ajouté des photos prises avec un filtre IDAS NB1 qui permet de récupérer l'hydrogène alpha.

For this image, I added photos taken with an IDAS NB1 filter which allows alpha hydrogen to be recovered.
