Horsehead and Flame Nebulas - Revisited (JDJ)

Horsehead and Flame Nebulas - Revisited

I revisited the Horsehead and Flame Nebulas with my new imaging setup consisting of a WO GT81 APO refractor and full-spectrum modified Nikon D5300 DSLR. The H-alpha regions really pop with the modified DSLR. Next I'm working on gathering H-alpha data with a narrow-band filter to combine with the OSC RGB data from the DSLR.

Horsehead and Flame Nebulas imaged on January 5-6 and 10, 2019 with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, Orion Skyglow Imaging Filter, and full spectrum modified Nikon D5300. Stacked using PI for a total integration time of ~3 hours using 120 sec subs at ISO 200. Subtracted darks, bias, and flats. Stacked using Batch Pre-Processing (BPP) script. Post-processed in Pixinsight: Cropped, gradient removal with ABE, Background Neutralization, Color Calibration, SCNR, stretched using Histogram Transformation Tool, Curves Transformation, HDR Multiscale Transform, Morphological Transformation, ACDNR noise reduction, and Color Saturation adjustment.

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.
