This was my first image taken with the SBIG AO-7 Adaptive Optics system connected to the ST-2000XM and RCX400. The AO-7 improved the tracking of the RCX400 substantially, decreasing the FWHM of the stars by a factor of 2. This led to a significant increase in the resolution of the image. Compare the image above with the one below which was taken a month earlier without the AO-7.
