The Great Orion Nebula (stock DSLR)

The Great Orion Nebula, with a stock DSLR and lens, processed to be close to natural color.

Total integration time: ~1 hours 8 minutes (subframes at 15 seconds; ISO 3200; core 1 minute of 2s subframes at ISO 3200)

After testing a few frames on Adobe’s new denoise and enhance rawconverter, I decided to give it go for this image.

Postprocessing: Lights calibrated entirely in Photoshop, first via Camera Raw Adobe’s Denoise (set to 10) and enhance. Newly created DNGs edited in linear 32-bit HDR, set to in-camera daylight balance and applied lens correction, color space HDR D3. Exported 32-bit TIFFs into DSS, 2x drizzle (slight crops in framing due to manual dithering)

Rnc-color-stretch for sky removal and color preserving stretch, using v1.02 to pinpoint blackpoint and to apply tone curve.

Photoshop for minor curve work, then Imagesplus64 for binning 2x2 average and minor sharpening. Photoshop then used for blending in core, changing color space to sRGB and JPEG and final crop (right side to frame image a little nicer)

Equipment: Stock Canon 90d and 100-400mm ii + 1.4x teleconverter at 560mm f/8 (71mm aperture).

Skies: Bortle 4/5 in outside of Paris, VA Feb. 3, 2024.

Tracking: Fornax Lighttrack ii. No guiding.

No darks, no flats nor bias frames used. Flats incorporated by lens correction and applied to linear data, bias embedded in exif data used by rawconverter.

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.
