Description
Using Hubble Space Telescope and WFPC2 we obtained short exposure images
for a hundred of BL Lac objects. The targets were centered mostly in the
PC using the F702W filter. Sources from various samples, including
objects of very different redshift (0.05 to 1.2), have been observed.
The high resolution and homogeneity of the images allow us to address
the properties of the immediate environments of BL Lacs with
unprecedented capability. We report here the results on the host
galaxies and compare their properties with previous ground based
studies. A number of peculiar features detected, that need follow up
investigation, are also briefly outlined.
