Thor's Helmet (Rodd Dryfoos)

Thor's Helmet

I posted this as a new image because it really is a whole new image that deserves its own posting--comprised of all new data--no older data from the FSQ reduced. I find the improvement over the version with OIII from the FSQ reduced to be subtle but definite. A good example of how small changes can have tremendous impact on an image. the other reason I posted this by itself is I am only 1/2 way finished collecting the OIII. It will be easier to compare this image with the final image with 3 more hours of OIII if they are posted together. This image has been a long time coming--2 months at least fighting the weather. The original is full FOV, the first revision is a crop to showcase the helmet. After I collect 3 more hours of OIII, I will post in the same fashion, a full FOV followed by a crop.

Version C includes 2.5 additional hours of OIII. The difference is subtle, but at full resolution there is a definite increase in sharpness and clarity. I will not be adding to this image, though I may adjust in an never ending march toward perfection - that mirage on the horizon

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.
