Handbook for the SX Spectrograph PRO with remote control

Introduction:

Spectroscopy of astronomical objects is a relatively unexplored field for many amateur observers, as truly compact, inex-

pensive and effective have been unavailable until recently. This situation is now changing and spectrometry is spectrographs

becoming popular as a way to extend the scientific value of amateur observations and to add a new dimension to the hobby.

The first SX Spectrograph was introduced in 2016, but was intended for local operation, where the user could change slits,

focus etc., by hand. The market has since evolved to include many remote observatories, well beyond the direct reach of the

observer, so we have now automated most of the spectrograph functions. The ‘remote’ spectrograph allows you to change

slits, adjust the imaging camera focus and wavelength setting, and switch on a calibration lamp, or flat field lamp, remotely.

General description:

The SX Spectrograph PRO is only 125 x 140 x 75 mm and weighs just over 1 Kg. It is solidly constructed in a machined

aluminium enclosure and so will not flex during use. The optical design is based on a highly corrected, 550 groove concave

reflecting grating, that provides a spectral length of 31 mm from 340 to 900 nM. The entire spectrum is accessible by adjust-

ing a sliding camera carrier, using a motor driven threaded drive screw, but most of the visible spectrum can be seen without

adjustment, when using an SX694 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 SX spectrograph design incorporates a Lodestar X2 guide camera, which observes the image 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 quite 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.
