What was the exposure for your subs and how are you finding manually focussing using the ha filter?
Very impressive mate.

Thanks Anthony, yep I'm having fun with this filter. These shots comprised of 3min subs @ gain 50 on this camera. Focusing is achieved by locating a relatively bright star first, crank up the gain and reduce the exposure to achieve a reasonably quick loop to notice the focus adjustments within a shorter period of time.

Thanks JA, the 7nm Ha filter virtually eliminates Melbourne's light pollution. The ASI120mm's sensor size probably crops M20 a little too tight to capture all the nebulosity, especially the blue reflection part. It does crop keeping the most interesting part of M16 though.

Another good add for the wonderful 6 inch Newtonian Telescope.

Thanks Alex, you've got to take the opportunities with the way the weather's been along the southeast coast of the country over the last 6 months or so. I have three telescopes, if someone said you can only have one, I'd probably keep the 6 inch Newtonian.
