Triangulum Galaxy - M33 (LRGB +HA) (James Hawks)

Triangulum Galaxy - M33 (LRGB +HA)

The Triangulum Galaxy (M33) is ~2.73 million light years from Earth in the constellation Triangulum. This is the third largest galaxy in our local group after Andromeda and our Milky Way. M33 has a bright apparent magnitude of 5.7, making it one of the most distant objects that keen-eyed observers can view with the naked eye under very dark skies.

This image is a two panel mosaic. It was captured in a Queen Creek (Arizona) Bortle 7/8 backyard using a Skywatcher Esprit 150ED telescope. The telescope is mounted on a 10Micron GM2000 HPS II mount. The camera is a ZWO ASI 2600MM Pro using Antlia VPRO LRGB and HA 3nm filters. It was captured over 9 nights (2022-11-20 to 2022-11-30). The images were stacked/processed in Pixinsight and fine-tuning done in Photoshop.

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.
