continuing to evolve on Carina and the keyhole

Hi team,
New scope arrived today and was surprised by a few hours of clear skies to play with it tonight. The scope is a william optics zenithstar81, with the 6aii flat.

Here's a go on Carina in narrowband, 32 x 1min O and H, 34 x 1min S.
And a link to astrobin for larger viewing. I shot at 200gain, 50 bias. I need to read about why its good to use lower gain.
