Portaocular Alpy para guiado

This eyepiece holder replaces the standard Alpy guiding port which is normally used with a centering & guiding camera. Associated with a reticuled eyepiece (not provided) - if possible with an adjustable reticule so you can move it in front of the slit - it allows manual centering of your target with the Alpy 600 + guiding (+calibration) system.

This makes an ideal accessory for one-evening practical workshop where focus would be on acquiring bright star spectra for exemple.
