THE OPTEC PERSEUS IS MADE TO ORDER. PLEASE CONTACT US AND WE WILL CONFIRM LEAD TIMES
Optec's 4-port Instrument Selector allows a user to select any of four instrument packages attached to their telescope.
Featuring 3 x 2" ports and 1 x 3", the Perseus allows almost every combination of equipment to be fitted. Internally the Perseus features a 1/8th wave first surface elliptical mirror with a 3-inch minor axis. The embedded circuit has a single push button interface to allow for instrument selection directly from the Perseus and an RS232 DB9 interface for remote control. LED indicators show the currently selected instrument.
Perseus is supplied with dedicated Server software. This allows Perseus to interface with the mount and focuser thus allowing for automatic offsets of focus and position to be applied when different ports are selected to allow for miniscule differences in alignment across the four ports.
Connection to the telescope and Port 1 utilise Optec's large format 3600 dovetail connection. For ports 2 to 4 the smaller 3000 format dovetail is used. All required adaption is extra and normally ordered for the desired application.
The Perseus 4 Port uses a minimum of 123.7mm of back focus plus the length of any adaption used.
Shown above is a recent installation we carried out using the Perseus fitted to a 400mm RC. In this install Port 1, the main 3" port featured a highly sensitive Andor IKON Camera, FLI Centerline filter wheel and Astrodon MOAG. This port is principally used for EXO Planet and Photometry. Port 2 is used for quick Astrophotography and features a QHY367C OSC camera and QHY filter wheel fitted with various filters to optimise OSC imaging. Port 3 has the head end to a Shelyak eShel spectrograph for high resolution spectroscopy. Port 4 is dedicated to planetary imaging and utilises a FFC Barlow, Pierro Astro ADC and FLIR Grasshopper Camera.
