The smallest model in the new "Black Diamond" line
The compact Newtonian offers high light collection by it's 114mm aperture. In contrast to a 76mm Newtonian, about twice the light is collected and hence nebulae, stellar clusters and galaxies appear brighter.
This Newtonian is not only a good light collector, but thanks to its parabolic primary also a good performer for moon and planets:
Skywatcher and some other companies offer short Newtonians with a spherical mirror, mostly of 500mm focal length. We do not recommend these instruments as they cannot deliver a defined image for magnifications of 70x and higher. In addition to that, very often an undersized secondary is used to mask up this problem but creating a smaller effective aperture, diminishing the capabilities of the whole instrument.
This light collecting, fast Skywatcher Newtonian has a parabolic primary which enables diffraction limited images, so that the theoretical resolving power is reached in practice. Only by doing this, such an instrument can be used for a successful observation of moon and planets.
