Carina Nebula 135mm

Tried to improve my previous attempt on Carina by getting more exposures (113 x 30s) and trying to avoid blowing out the core by taking shorter subs (30secs vs 60 secs) at a lower iso (800 vs 1600). Took darks and biases and processed in Siril. Revised image: Took more subs the following weekend (199 x 30s) but accidentally changed f ratio by 1 stop from f/28 to f/3.2.

Description: Combined existing data (113x30s at f/2.8 iso800) with more data from following week (199x30s at f/3.2 iso800). Separated into starless and starmask in Siril and then recombined using asinh transformations on both data sets. Found I was able to get a bit more detail in dark nebulosity within the starfield around the Carina nebula and to bring out the nebula with more brightness.

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.
