Ive decided to keep going, bagging more obscure H alpha regions in the deep south.
Tried shorter ISO 1600 shots for a change
RCW 70, 5x5 mins ISO 1600, its quite a low surface brightness object, and is surrounded by extremely faint widespread nebulosity
RCW 65, this is an odd one as theres several separate bits, and a large very faint area bottom right. One of the bright bits may be RCW 66. Star Atlas pro also indicated that there is a very faint,open cluster called RUP 105 (Im sure weve all heard of it and can find it by memory LOL). Its given as 13 arc minutes diameter. Its so spare it appears as a slightly greater quanitiy of stars just to lower right of the brightest nebulosity in the image.
Both these objects are located right next to the Southern Cross (between Mimosa and Acrux to be precise, but too far apart to get in one go. A nice planertary nearby will have to wait as cloud ended proceedings tonight.
I love the deep southern sky, so many little gems awaiting observation.
