Wizard Nebula

This was a tricky one! At 1485mm f/7, I needed 10 min subs to see much of anything in individual frames. (dual narrowband)

This work combines 3 sessions totaling over 18 hours of 10 min guided subs in low-moon, backyard conditions. I processed Ha and [OIII] separately, and used a modified HOO2 palette that reduced the Ha background and boosted [OIII] to find this balance. In this balance, the shock waves and details carved out by radiation and stellar winds around the chain of bright new stars near the Wizard's "chin" stand out.

In postprocessing, I used some minimal Topaz denoising, classic unsharp mask, and then some mild wavelet sharpening in Registax to bring out more of the dust and gas cloud details. I used some very mild star reduction in AstroPixelProcesser to reduce star size and intensity by 15%, but I like to take a light touch on that. To me, it's interesting to see how faint this beautiful DSO is relative to the stars.

Hope you enjoy!

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.
