Very deep image from my good friend Luigi Fontana: he allowed me to process it fully in PixInsight 1.8

Taken with unmodded Canon EOS 6D on an Orion ODK 12" telescope.
Note the bluish HII regions: the unmodded camera is almost blind to H alpha, but can correctly capture the bluish, but usually fainter, H beta emission.

Please enjoy at full resolution
Thank you Luigi

Revision B: a little bit of contrast

Immagine molto profonda di M33 ripresa dall'amico Luigi Fontana ed elaborata da me completamente in PixInsight 1.8

Ripresa con una Canon EOS 6D non modificata su un telescopio Orion ODK 12 ".
Notare le regioni HII bluastre: la fotocamera non modificata è quasi cieca all'H alpha, ma può correttamente catturare l'emissione H beta solitamente più debole.

Godetevela a piena risoluzione
Grazie Luigi

Revisione B: un po' più contrastata.
