Horsehead & Flame Nebula

Revision title: HorseHead & Flame Nebula Nov 2021

My first try of the Horsehead Nebula. This is straight OSC camera , just using a UV\IR cut filter. ASI 533MCPro @ unity gain.

This consists of two sets of pics:
- 25 180Sec shots
- 45 300 Sec shots
A total of 5 hours integration.

Processed with Darks and Bias frames. I need to shoot some flats - Camera is new - I've not had time to run those yet - sigh.

Where I'm situated there is a light dome to the south & east - right where Orion happens to travel through the sky.

I think I stretched the data a bit too much. I'll have to try more integration time. Shall I take longer subs or just more 300 second ones.

Description: I was able to gather 29 more 5 min subs - added to the original data. Data summary:
- 25 - 180 Sec subs
- 74 - 300 Sec subs
Just over 7.4 hours of integration time.

Pic was processed with same settings in Astro Pixel Processor. Ditto for the Post processing in Photoshop - although more of that work is a manual process, thus not 100% same.

As always - comments welcome.

Description: I finally had a chance to shoot some flats - they've been added into the integration. A few tweaks in Post Processing as well.

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.
