“…The observation of VHE blazars has started to become less biased: Not only blazars with hard spectra or in a flaring state are now detected, but a much higher dynamical range of VHE γ emission levels and states is probed, flare statistics studies (e.g. [22]) are within reach, and generic blazar properties start to become accessible. Thus the era of VHE blazar astronomy has been entered-astronomy being understood as the study of generic properties of a given class of objects.…”

Since 2002, the number of detected blazars at Eγ > 100 GeV has more than doubled. I study all currently known BL Lac-type objects with published energy spectra. Their intrinsic energy spectra are reconstructed by removing extragalactic background light attenuation effects. The emission properties are then compared and correlated among each other, with X-ray data, and with the individual black hole masses. In addition, I consider temporal properties of the very high energy γ-ray flux. Key findings concern the flux-black hole mass and variability scale-black hole mass connections and the correlation of the spectral slope and the luminosity. As a specific application, the study allows to constrain the still undetermined redshift of the blazar PG 1553+113.1. See http://www.mppmu.mpg.de/∼rwagner/sources/ for an up-to-date list.

The MAGIC 17m diameter Cherenkov telescope will be upgraded with a second telescope with advanced photon detectors and ultra fast readout within the year 2007. The sensitivity of MAGIC-II, the two telescope system, will be improved by a factor of 2. In addition the energy threshold will be reduced and the energy and angular resolution will be improved. The design, status and expected performance of MAGIC-II is presented here.
