Suburban Pelican Nebula

Taken from my suburban Orange County CA backyard. The data was from shortly after I first acquired a narrowband setup. I got my AO-8 and SBIG STT 8300M to track using the AO (hadn't figured out traditional guiding yet) and had very nice subs with <2 pixel FWHM on some subs. Since this was some of the first data I had gathered, I figured that was normal!

This was really fun to revisit as I've learned much more about how to process the data.

30 minutes subs, 7 Ha, 16 OIII, and 8 SII. 15.5 hours total. Ha was blended in to the OIII at 3:1 and into the SII at 3:1. The Green channel is a combination of the blended OIII and SII data. Since the Green was essentially a psuedo-luminance, I blended that with the Straight Ha data for the luminance channel. Masters and RGB created in CCDStack. The rest of the processing was done in Photoshop.

Star reduction with minimum filter, fine sharpening with unsharp mask, large scale sharpening with a high pass filter.

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.
