SH2-240 | The Spaghetti Nebula in Two Panels

Looking for a warmer place to rent a home for a while, I naturally started with the Bortle maps! We ended up choosing a community outside of Sedona Arizona. This was a Bortle 3 location - which is pretty dark - but then I ended up shooting narrowband! I've had the Spaghetti Nebula on my list for a long time and, being a Winter object, it's not accessible from Portland. So NB it is.

As large as the FOV is on the QHY600M/FSQ106 combo, 240 is still far too big. So this required a two panel mosaic to shoehorn in.

We ended up getting some cloudy nights so this doesn't include as much data as I would like, but still a respectable 23.8 split across the two panels. Twice as much would be better.

The mix is straight HOO. Because these SNRs tend to have very different Ha and OIII components, I was not able to rely on the Ha for Luminance. The resulting Cyans have been shifted slightly to the blue.

Noise reduction was with Topaz Denoise 5.1. I added a touch of Topaz AI at the end, masking off all but the shadows.

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.
