Horsehead Nebula -- Monochrome -- H-alpha

Imaged 1-20-23 from the Sagrada Observatory, Las Cruces, NM
Telescope: 24" f8 RC CCD Camera: FLI-PL-09000 3nm Ha Filter

The skies were clear last for this image, although the wind was up and the seeing conditions fluctuated in the 3 to 4 arc sec range -- so, I decided to image a simple sequence on ic434 in monochrome with H-alpha.
Image data was: 58 x 300 seconds Ha 1x1

I tried to reveal the turbulent structure in and around this interesting nebula.

By the way... I still have the Spider Vane masks installed, which are suppose to eliminate the diffraction spikes. I notice that the stars have a different diffraction pattern -- not that pleasing. I'm going to remove these Masks. It was a fun experiment...

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.
