Veil Nebula HOO with RGB Stars (Rodd Dryfoos)

Veil Nebula HOO with RGB Stars

Here is a comparison of the Eastern Veil Nebula using DSW Atacama Desert data, and my own data, collected in my backyard in Bortle 6. The original is DSW and Version B is my data. The DSW data was taken with an AP 175 at native, and my image was collected with a TOA 130 and is a 2 panel mosaic. The stars are not RGB. Much of the difference is no doubt a processing difference--I have learned a bit since I processed my data. For the DSW data, I integrated the Ha and OIII stacks into a synthetic luminance and used that to make a HO-HOO image. I inserted the RGB stars in the linear state using a gently stretched RGB image. A very noticeable difference is the blue channel--I removed much more green from my data than I did from the DSW data. that's purely a personal taste thing, and I am uncertain which green level .I like better--I can appreciate them both.

The DSW data consists of 11.5 hours of data, 3.75 hours of Ha and O, and about 7.75 hours of RGB. I used the RGB data for the stars, so it was a bit of a waste. I tried to combine the BB and NB data, but was not satisfied with the results. My data consists only of Ha and OIII-15 30 min subs of each per panel, so 30 hours total. A very interesting comparison.

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.
