Heart Nebula IC1805 and Melotte 15 (large field)

Heart of the Heart Nebula
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.
Our firts target is IC1805 an emission nebula and star cluster Melotte 15.
Clouds in this aarea are sculpted by stellar winds and radiation from massive hot stars in the nebula’ssar cluster, Melotte 15 (about 1.5 million years young).
This 15 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, we are quite happy with this result.

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.

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 !
