NGC 3324 Gabriela Mistral Nebula

BiColor Ha Oiii image of NGC 3324, aka Gabriela Mistral nebula due to similarity of the shape with the facial profile of the Chilean Nobel poet. Her nose is on the right.

This image is intentionally left uncropped to see the full field of the asi-1600.

The Ha channel was directly mapped to RGB based on perceptual values for the visual impression of the H-alpha and H-beta lines. Oiii was mapped to a similar RGB for the Oiii line.

The Oiii is relatively weak in this nebula so it was boosted by a factor of two and linearly combined with the Ha RGB. The resulting RGB was then stretched using levels in PhotoShop. No other processing, sharpening, or denoising was performed.

The image was acquired and stacked using custom software - including automated plate solving, focus, and acquisition of the OAG guidestar by rotation of the Pyxis to the specified angle.

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.
