IC1318 - The Butterfly

302 x 1min exposures, 80 bias frames, 90 darks, 60 flats, 60 dark flats
Taken in Scarborough, Ontario in the backyard across two nights

DSS - stacked in 2 groups

Linear:
Dynamic Crop and Rotator
Background Neutralization
Automatic Background Extraction
SCNR
Image Solver script
Spectrophotometric Color Calibration
EZ Denoise
Stretch to Non-Linear

Non-Linear:
Starnet2
Channel Extraction into H-alpha, S2 and Oiii
Deleted Oiii and played with the S2 channel to make it similar to H-alpha
Pixelmath to create a synthetic Blue channel
LRGB combination using H-alpha as L and R, S2 as B with the synthetic Blue channel acting as G
RangeMask to protect the "wings" to work on the background
Curves to adjust the colours to re-create SHO (Hubble Palette) and CorrectMagentaStars on the starless image
DarkStructureEnhance to bring out the dark structures
Curves to taste and Saturation
Pixelmath to combine the starless with the stars
EZ Deconvolution and save as TIFF then a very minimal denoising run on Topaz Denoise

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.
