I've been using a Hawke Panorama for HFT and been more than happy with it.
Clear bright, optics (for the money), excellent Half mildot reticle, very little parallax.
Holds zero well, Good depth of field as its only a 40mm front lens. Most others seem to be 42 or 44mm.

Unfortunately according to the deben website it looks as though this range is discontinued.

Cheers
