IC 434 LRGB

I've been imaging the Horsehead every year since I took up astrophotography. It is an object that is one of the most imaged there is, but my quest over the years has been for increased depth and detail. There is so much here, ranging from the bright nebulae themselves to the extended nebulosity above the Flame and Horsehead and the intricate structures below, that I find myself never satisfied with my efforts. My last effort was first light with the 2600 MC Pro, about four hours, with the Horsehead in not the best of locations in the sky, passing over a light pollution dome. It was a good effort, but I wanted better. So this one adds four hours of luminance to that data, taken at Bin 1 with the ASI 294MM for maximum resolution. The luminance data was taken with a 0.8x reducer to give a similar FOV to the larger APS-C sensor of the 2600 MC Pro. My big regret here is that the color data was taken in two sessions - and in doing so, I had to crop a bit of the frame, since the 3 degree alignment that was the default in SGP meant I had to cut off some of the dark nebulae beneath the Horsehead that were revealed beautifully in the luminance data. Such is life. I suppose one can say the world doesn't need one more IC 434 image, but I certainly did, so this one's mine.

A big thanks to my friend and fellow MAS member, Gabe Shaughnessy, whose critique of my original processing led me to go back and reprocess and produce a better image. There is much I have learned from him and my other imaging colleagues at MAS and much I have to be thankful to them for.

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.
