Cone Nebula in HaRGB

Revision title: (Reprocessed)

Image taken across 4 nights this February, 2 nights devoted to Ha and two nights for RGB data. Processed via LRGB combination in PixInsight, including the normal de-noising, deconvolution, etc. Really like this object and the strong red signal that comes from it. In the RGB, the red was very strong, but only a small amount of green and blue for a similar amount of exposure time. I will probably revisit the processing again after I get some more practice using PixInsight.

Exposure Data: 63x600s Ha, 49x180s R, 45x180s G, 50x180s B (HaRGB)
Camera: QHY183m
Filters: Astrodon 3nm Ha, Astrodon RGB
Bortle Scale: 7
Optics: C11 XLT w/Starizona reducer-corrector
Image train: ZWO 1.25” filter wheel, Pegasus Scops OAG, Pegasus Falcon rotator
Mount: EQ6-R Pro
Guiding: QHY 5-III 178m w/PHD2
Software: NINA, PixInsight, Photoshop

Processing: Starting from 4 calibrated stacks, Ha & RGB. On the RGB channels, used EZ Denoise, then linear fit the three channels, followed by EZ Soft Stretch. For the Ha, I first did deconvolution by creating a Starmask using Starnetv2, a range mask to select the light portions of the frame, and a PSF using the Dynamic PSF tool. After deconvolution, I selected the background with another range mask and used MultiscaleLinearTransformation to remove noise from the darker background. I create another range mask capturing only the very brightest portions of the image and used MultiscaleLinearTransformation again with the “bias” option on layers 2 and 3. I then stretched the Ha image using EZ Soft Stretch and combined the channels using LRGB combination, followed by some curves adjustments.

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.
