It's always a pleasure to announce a new instrument in our catalog, but this pleasure is increased by the fact that this instrument has been widely requested and even suggested by several observers. It was Robin Leadbeater - many years ago - who first alerted us to...

Description
Of course, the switch will be even simpler if each module is equipped with its own camera, but this is not a requirement.
Warning: remember to redo the reference images (flats and calibration in particular) after the exchange.
When ordering, remember to choose the slit that corresponds to your configuration (this module is sold without slit).
Note: It was Robin Leadbeater who first suggested – several years ago – that we make a variant of the Alpy 600 for observing weak targets. Thank you Robin !
