NCG 1499 in SHO Hubble Palette

Data acquired over 7 nights in 2021: 10 Oct, 19 Oct, 20 Oct, 28 Oct, 31 Oct, 2 Nov and 4 Nov.

The SHO Channel Combination was processed with PixInsight BackGroundNeutrlaization and ColorCalibration, and SCNR was subsequently used to remove green oversaturation. Most denoising, sharpening and final color adjustments were made on a starless image made using StarXTerminator. The SII Master frame stars were then placed back into the image using LRGB Combination, with RG&B unchecked. The best final image was made when adding the stars back through a star mask, so not to minimize the color and contrast of the main nebula with the dimmer background of the stars only image.

Looking back at master frames and results in the final image, my next attempt at this object would be to acquire a huge amount of OIII data, perhaps 4-5 times that of the total of Ha and OIII combined. OIII is weak but very much present and should not be marginalized as I did during these subframes acquisition.

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.
