IC 1805 - The Heart Nebula, 2022 Acquisition (Godfrey Benjamin)

IC 1805 - The Heart Nebula, 2022 Acquisition

This was a test to try out the AT72EDii along with the ASI120mm. I did the Heart Nebula last year, with just the mount and the camera and the Optolong L-pro, but that was about 300+ images at 30 seconds each with ISO 1600. I wanted to see how the equipment would play with Kstars/Ekos, and to test out longer exposure time. I am really proud of the image thus far - just an hour's worth of data in the backyard gave me enough to work with.Acquisition Date: Sept 8 2022

ISO 200
20 x 180 sec subs
No calibration frames
Location: Scarborough, Ontario, Canada - Bortle 8

Equipment:

Camera - Nikon D5300
Telescope - Astro-Tech AT72EDii

Focal Length - 343 mm using Astro-Tech 0.8 Reducer/Field Flattener

Guidescope - SVBONY SV165
Guide Camera - ZWO ASI120mm Mini
Mount: IEXOS-100
Acquisition Software - Kstars/Ekos running on Astroberry via Raspberry Pi, PHD2 for guiding

Processing:

Stacked on Deep Sky Stacker - all subs, and saved as a TIF file
Edited using Pixinsight:

Dynamic Background Extraction - subtraction to remove gradient and division for vignetting
Photometric Color Calibration
Multiscale Linear Transform with Linear Mask for noise reduction
Extracted Ha from R channel to create Luminance layer- Deconvolution, noise reduction via Multiscale Linear Transform and Histogram Transformation to stretch, then set aside
Histogram Transformation to stretch image
SCNR to remove Green cast
HDR Multiscale Transform
Curves Transformation
LRGB Combination using the Luminance layer and combined with final image
Curves Transformation to make the background slightly darker
Starnet to separate the stars from the image

the stars were put through the CorrectMagentaStars script before using Pixelmath to combine both images together

Saved as TIF

Topaz Denoise

Slight noise reduction keeping the details intact
reopened in Pixinsight to save as JPEG

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.
