Long Exposure on M33

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.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
