Galaxie du Tourbillon (M51) - 3h45/11h45 - 76/342mm - 2.26 arsec/pix - L-Pro


Recommended Posts

Bonjour à tous,


Je continue dans ma série de galaxie en retard. Sur cette M51, j'avais 11h45 d'acquisition mais j'en ai gardé que 3h45. J'ai trié mes brutes sur le volet sur 3 critères: fond de ciel, FWHM et rondeur. Je vous mets aussi le champ complet.


75x180s, ASI2600MC pro, TS 76EDPH f/4.5 (f = 342mm), filtre L-Pro, champ = 3°56' x 2°38' / échantillonnage = 2.26 arsec/pix, AZ-EQ6.





A comparer avec la tentative précédente:
