Horsehead and Flame nebula

The photo was taken utilising a a remote telescope in the Rio Hurtado Valley, Chile with a 200mm lens and F-ratio 2.0. this is a crop in on the Flame and Horsehead nebula from the original widefield of Orions belt at 200mm

I took 2 x 180seccond exposures for Red, Green, Blue and a narrowband Hydrogen Alpha filter With the telescope centred on the star Alnitak

I aligned and stacked the raw monochrome images in Deepsky Stacker and combined the pictures in Pixinsight where i also performed post processing such as noise removal and histogram stretching. I mapped the H-alpha to the red channel but also added 5% of the H-alpha to green and blue channels to provide a more pleasing hue of the ionised gases

let me know what you think. this was my first time processing monochrome data from a remote source.

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.
