Description

The Bubble Nebula Crop

Further testing with the Astro Tech 12" F4 Truss from last week on our only clear night since early November, this is just 4 x 5 min luminance and 3 x 5 min RGB. Sky conditions were below average and therfore focusing is quite soft, again I was using the stock Astro-Tech Focuser.
