Rosette Nebula (stock DSLR)

The Rosette Nebula found in the Orion Constellation, photographed to be close to (but not quite) natural color (little on warm side). My second attempt at this target, acquired in December 2023, with a stock 90d and canon 100-400mm ii lens.

Total integration time: 2 hours, high clouds interrupted session.

Lights were first calibrated with Adobe’s new denoise (set to 7) and enhance rawconverter.

Newly created DNGs processed as 32-bit HDR, in-camera daylight balance and applied lens correction, color space HDR Rec2020. 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 changing color space to sRGB and JPEG.

Equipment: Stock Canon 90d and 100-400mm ii at 400mm f/5.6 (71mm aperture).

Skies: Bortle 4/5 in VA December 2023.

Tracking: Fornax Lighttrack ii. No guiding.

Subframes: 27 seconds, ISO 1600. No darks, no flats and no bias. Adobe's rawconverter applied flats by lens correction to linear data and incorporated bias from exif data.

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.
