A Walk in Cygnus From Crescent to Propeller– 2 panels - 4 palettes (Axel)

A Walk in Cygnus From Crescent to Propeller– 2 panels - 4 palettes

This was a big but exciting project to capture SHO data on 2 panels during summer short nights.

I used my Canon 200mm paired with the ASI1600MM under heavy LP (SQM 18.3)

Image integration was also epic with 285 O3 frames ; 207Ha and 219 SII but APP made the job easily.

The next challenge was the processing : I opted for HOO / HOO ToneMap / SHO / SHO ToneMap.

The idea was to try as much tonal variation as possible with these 4 common techniques.

Still, I could have added a pinch of SII in the HOO but opted not too.

A few comments on each image

HOO : weak O3 but discernable, red / pink tones

HOO TM : O3 more discernable, brownish area

SHO : O3 is weak and totally overpowered by Ha and S2. Interesting palette even if some may find it too monotone

SHO TM : pretty photogenic, high impact I guess, lots of shades.

I like all 4 images and I’m pretty happy with the end result.

Special mention to my friend Cyber (Victor Van Puyenbroeck) and Jon Rista : thank you for your feedbacks !!!!

Let me know what you think of this project and which image you like most !

CS to all !

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.
