Thanks all. Yep it's great. Had to get a fast memory card to do the 4k stuff. 30x live view makes for accurate focus. Only bummer is my pc and 7th generation 16 gb ram laptop take ages to process 4k video and converting the 30 megapixel images. Houghy has kindly lent me his portable Polarie mount so I might be able to get some dark sky widefields soon
