M33 - HaLRGB

M33 - Our second nearest neighbor, about 3 million light years away. The spiral galaxy spans about 60,000 light years and hosts about 40 billion stars. It is similar to milky way but estimated to be half the size of it. A distinctive region in the galaxy is NGC 604 which is considered as a star birth region.

About the Image Acquisition -
This image was captured on multiple nights between 21 October and November 10 whenever weather permitted and the target was available before it sets into trees in my community.

7 Hours Ha
2 hours L
2 hours RGB

Added the Ha by continuum separation method. Personally, I felt LRGB version of this image had better details than HaLRGB.
Adding Ha to image had to be done at cost of losing some details on the LRGB version. And I chose to do it because Ha details look pretty on the galaxy.

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.
