Description

This was taken through the ITU scope in Southern Spain in Fregenal de la Sierra, and consists of fifty nine 30 sec exposures and thirty 300 sec exposures merged, using HDR combination in PixInsight to protect the core from over saturation. Even so, I struggled to tame the saturation levels but managed to find a way using HDR wavelets with a strong mask to keep some of the normal appearance of the core, whilst reducing it back enough to bring forth the 'propeller' in the centre of the core itself. Not easy work, in spite of it being an easy object to take! I hope to process it with the coloured data soon.
