Ghost of Cassiopeia - Hubble Palette

IC 59 and IC 63 in SHO narrowband

Taken from Bortle 5/6 backyard.

Imaging run included 20 exposures (600 seconds each, unguided) through each filter (H-alpha, Oiii, Sii each at 3nm bandpass).

10Micron GM1000HPS mount, QHY268M-Pro camera, Astrodon and Chroma filters, TEC 140 scope. SGPro for imaging run. Pixinsight, Photoshop and Lightroom for processing.

This faint nebula could really use LRGB from a Bortle 1-3 sky plus Ha and Sii, and could use 3-4 nights of integration. It's incredibly faint. In noise polluted skies (and the near full moon last night), I would not attempt this target with LRGB filters, OSC, or even narrowband at wider bandpass. SNR would likely be too high to extract a strong image.

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.
