Nebulose Sh2-112 e Sh2-115 in Cigno

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

Elaborazione (finalmente!) di foto scattate in due notti dell'estate 2016 con la gloriosa 350D.

Autoguida e dithering. Temperatura esterna: circa 12-16 °C + ventola 0.7 A

ELABORAZIONE:

Con DeepSkyStacker: calibrazione (dark, flat, darkflat), somma, drizzle.

Con PixInsight:

FASE LINEARE:

- neutralizzazione del background con BackgroundNeutralization e DynamicBackgroundExtraction

- bilanciamento iniziale dei colori con PhotometricColorCorrection e SCNR

- deconvoluzione (con maschere stelle e parti molto luminose della nebulosa)

- riduzione del rumore (“denoise”) con MultiscaleLinearTransform (MLT) (maschera parti deboli)

FASE NON LINEARE:

- stretching con EZ Soft Stretch

- stretching con MaskedStretch e sovrapposizione sue stelle (prese con maschera/StarNet) su EZ SoftStretch

- riduzione stelle con EZ Star Reduction reiterato

- lieve esaltazione/saturazione dei mezzitoni con CurvesTransformation (CRV) (maschere con StarNet)

- riduzione rumore (“denoise”) con MLT (con maschera di selezione toni bassi e medi)

- esaltazione nebulose di fondo con HistogramTransformation (HT) (con apposita maschera)

- ColorSaturation e CRV (con maschera di luminanza)

- ulteriore riduzione stelle con EZ Star Reduction

- esaltazione nubi di fondo con LargeStructureEnhance

- wavelet per esaltazione contrasti luminosi con AdvSharpening

- lieve applicazione di LocalHistogramEqualization (con maschera nebulose luminose senza stelle)

- riduzione rumore basse luci e mezzitoni con MultiLayerTransformations

- miglioramento contrasti con HT e CRV

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.
