This is my first take on the Heart Nebula, also known as NGC 896 or IC 1805. What do you think?
Used the Optolong L Extreme 2" DuoNarrowband Filter.

Siril: Color Calibration, Background Neutralisation, StarNet -> Starless image: GHS: Modified Arc Sine stretch, Ajusting Blackpoint, Color Calibration and Green Noise Removal, Saturation.
-> Starmask subtle stretch with GHS.
Both Pictures in Photoshop: Starless -> Bit of Sharpening, Contrast and sligtly lowered "lights" in Camera Raw Filter. Removed Halos from the stars with magic fill tool.
Starmask -> Fixed elongated stars by duplicating the layer and setting it on darken blend mode. Used offset effect under Filter -> Other (Filters) -> Offset / wrap around mode

Back to Siril: combined stars and starless into the final Image you see here

Hope you like the picture.

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.
