International conferences are an excellent opportunity to create a network of knowledge and exchange opinions and techniques.
During the last CEDIC 2024 in Linz I had the pleasure of meeting Christoph Kaltseis, one of the organizers and his friend Ulf Backmeyer who are starting a new remote observatory in Greece: hellas.sky (https://hellas-sky.com/).
Thanks to them I was able to preview the data that the observatory will be able to produce.

This is the third test: the Rosette Nebula with narrow band data and composition according to the classic "Hubble palette".
This composition is certainly one of the most pleasing to the eye among simple false color compositions.
The SII signal is associated with the color red, the Halfa with green and the OIII with blue, appropriately balancing the fluxes in order to have a balanced white point (by keeping the original fluxes the image would be almost completely green because the signal of hydrogen dominates over the others).
The only variation compared to the original Hubble palette are the stars processed separately in order to reduce the "magenta stars" effect typical of this composition.
The images are all 180 seconds long: 30 Halfa, 30 OIII and 42 SII

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.
