Orion Optics AG12 astrograph - First Light! - new Starfire comparison

I have posted a brief report in the equipment section so I will just post the images here

First light with the new 12" F3.8 Orion Optics UK Astrograph went quite well, collimation is a key factor and I have it pretty close but I think I can still improve it a little..?

All short test exposures as the night was all about making sure that everything worked and familiarising myself with the new platform

Crap light pollution, less than cooperative seeing and a 3/4 moon

NGC 6334 Cats Paw

Centaurus A

Omega Centauri in a 2.6deg diagonal field (seeing was soft )

To see the power of this platform, compare the 10 X 2min Ha Cats Paw image above taken with the AG12 to a 9 X 10min version taken with the standard candle best in the business 6" Starfire:
