Lightweight and compact.
The H400 f2.4 astrograph is the ideal platform for widefield imaging and all-sky surveys. The H400 features a 5-inch corrector and motorized focusing with absolute encoders. The H400 ensures precise focus and high-resolution data acquisition of the night sky – in the shortest possible time! Fits perfectly with the /ASA Direct Drive mounts/.
The H400 was selected as the instrument of choice for the Super Wasp II Exo-planet program, a consortium of universities and space agencies including: Geneva University, Leicester University, Queens University Belfast, the University of Warwick, the German Aerospace Center DLR, and the GOTO project.
This very fast 400mm telescope is also available as a /package in combination with a ASA DDM100 Direct Drive mount!/
