The Rosette (C49) in Narrowband Natural – First Light for William Optics FLT 91

As I mentioned my last post, this is a first light image with a new William Optics telescope that I am testing, the Fluorostar 91 (https://williamoptics.com/fluorostar-91). The FLT 91 is an Apochromatic refractor with a focal length of 540 mm and an aperture of f/5.9. Over a seven day period I was able to collect about 17 hours of good quality narrowband data (there was an 80-100% Moon during the collection period), including 8 hours of Ha subs with an HFR range of 1.6-2.2. My previous post of these data was an SHO rendition (https://www.astrobin.com/oq39mu/?nc=user). This is a “natural” palette version using these same data (use this link for a full description of my narrowband natural processing procedure, https://www.astrobin.com/0th11x/?nc=user, Version C). For this object, I prefer this “natural” look over a classic Hubble palette. What color palette do you favor?

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.
