Just fitted the 10:1 focuser to the 150 newt today and after a bit of visual tried a test on a cluster in Carina. No idea what its called but, best I've ever got in DS.
1 frame, 20 secs with the DSI, stretched in Nebulosity and auto levels in PS 7.
Not used to PShop yet so had another play with it in PSP7.
(After comparison with other images on the forum, its Eta Carina )
