Clear Night of Video Broadcasting (Astrocasting)

Last night was the first clear night in ages, and the boggy water-logged back yard has dried up enough to support the mount again, so I had a night of Astrocasting again.
Been months since my last broadcast.

I started the night with a 16~160 lens from Bert (Avandonk).
I had to fit an IR/UV filter inside the lens as the stars were horrific.
Last night was the first chance to try it out.

The stars were markedly improved but I was having trouble picking up nebulae.
I have to learn which settings work best with this lens.

The 1st image in the collection below is with the 16~160 lens. See how faint Tarantula is.

After unsuccessful attempts, I switched over to the Saxon 120mm f5 Achromat Refractor with a 0.6x Focal Reducer.
All the other images are from the Saxon.

Every image is a screen grab of live video. No stacking, No processing. Just a single screen Grab.
These give a great example of what you see on screen doing 'Live' Video Astronomy

Camera used: Samsung SCC-A2333P
