Automated, reflective Spectrograph with built-in Lodestar PRO Guide Camera

Description

The Spectrograph PRO is an automated version of the SX Spectrograph. It allows you to change slits, adjust the imaging camera focus and the wavelength setting, and switch on the calibration lamp, or flat field lamp, remotely. It is machined from a single block of aluminium to ensure it will not flex during use or changes to the ambient temperature. The optical design is based on a highly corrected, 550 grooved concave reflecting grating, that provides a spectral length of 31 mm from 340 to 900 nM. The entire spectrum is accessible by adjusting a sliding camera carrier, using a motor driven threaded drive screw, but most of the visible spectrum can be seen without adjustment, when using a TRIUS PRO-694 imaging camera. A 6 position slit wheel, with various slit widths and lengths, is provided and will allow the sensitivity and resolution to be optimised for the user’s project. The best resolution R factor when using the smallest slit width (20 microns) is approximately 1500 – 2000, depending on the F number of the telescope used.The Spectrograph PRO incorporates a Lodestar PRO guide camera, which observes the imaging field via a 10% / 90% beam splitter cube. The slit is not directly visible in the field, but its position co-ordinates are provided and marked by a cursor box, generated by the PHD2 tracking software. It is therefore easy to move the object of interest into the slit cursor box and then to select any convenient guide star in the Lodestar field for tracking.
