Crop Version of our previous version to focus on Melotte 14 and Heart Nebula center :
>>> Our first picture with our remote imaging setup in south Portugal (Alelentejo Remote Observatory managed by the ARO TEAM).
Our team named AstroDarkTeam is a team of two passionnate french amateur astronomers : Stephane Rolland and Pascal Gouraud
We have installed our setup in south portugal (EQ8-R + TOA130) on mid-october 2021 and we have been imaging since end of October 2021. We have got more than 20 clear nights, that demonstrate the site quality.

Our first target is IC1805 an emission nebula and star cluster Melotte 15 in te nebula centert. Clouds in this area are sculpted by stellar winds and radiation from massive hot stars in the nebula'star cluster, Melotte 15 (about 1.5 million years young).
This 200 light-years wide field view includes emission from ionized hydrogen, sulfur, and oxygen atoms. The Heart Nebula. IC 1805 is located about 7,500 light years away toward the constellation Cassiopeia.

Regarding imaging sessions, we have got some issues with thermal aumplitude and humidity. Some improvements still to be done regarding subframe exposure (moving to 15 or 20 minutes) and better subframe selection.
Regarding processing, we habe been unable to integrate LRVB shots to improve star colors, so still to be improved for future pictures.
For a first run, 55 Hours for total exposure with narrowband chroma filters, and automated remote imaging challenge, we are quite happy with this result aand we have still to progress in 2022 !
We take this opportunity to sincerely thank the Astro A.R.O. for their welcome, their advice, the quality of the site and the services provided, in particular an irreproachable power supply and satellite communication perfectly adapted to the remote (what a pleasure after a good night's sleep to find fresh photos of the night in your computer)

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.
