Howdy all
Heres some more Ha images, this time taken with Berts mighty 300mm Flourite lens
NGC 3567 etc. is 5 x 5 mins ISO 200, and Eta carina is 6x200 sec. Ive used my 6 inch scope also, with the ha filter, as well as the 10 inch, but Berts lens, in its rock solid mounting rings he also supplied work so well, I really must do some more Ha imaging with it, especially one of the new UK ST Ha survey planetaries they found thats quite large in diameter. These images were taken a little while ago but processing them better, the lens is returning sharper results then the 6 inch.
Larger sizes

The learning curve to improvements with astrophotography is no only using the equipment better, but better processing the images the equipment provides. When I first took these images they didnt seem to look that good but now Im especially happy with the Eta carina shot
