Homunculus in LRGB

I always have fun trying to get the most details imaging the Homunculus Nebula with my setup. It is a very hard target, given its small size and huge dynamic range. I wanted to try my QHY183 camera, with its small pixels, combined with a 2x barlow. I did several SER videos with a small ROI and Sharpcap, using LRGB filters. Collected a total of 5000 frames, exposed at 500ms for L and 1500ms for RGB filters, using the camera at gain 1 (most dynamic range) and 16 bits, so that the peak of Eta barely saturated.

Processing was very unconventional, and had to try many workflows. I like the final result, as it reveals fine structure in the lobules.

OTA used was my AP167 FLZ, with an AP advanced barlow at 2x approx.

Description: Noticed that the barlow flipped the image, so I flipped it back. Also tweaked a bit more the post processing to gain more contrast and sharpness.

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.
