Instrumentation

We currently have two instruments available for use on the Alluna RC20 telescope: an STL-1001E camera from SBIG Astronomical Instruments, and CCDSPEC from Elliott Instruments. We are also developing a new Zoom Lens Spectrograph (ZLS2) in collaboration with Elliott Instruments. ZLS2 follows in the footpath of the original ZLS, further details of which are available page and in this paper.

SBIG STL-1001E

Formerly used for imaging with the 14 inch Meade telescope, an STL-1001E camera from SBIG Astronomical Instruments is now mounted to the Alluna telescope. This camera is the primary camera of the UBO and has been used throughout the commissioning process.

Number of pixels	1024 x 1024 pixels
Physical size of pixels	24 x 24 um
Angular size of pixels	1.39 arcsec/pixel (at f/10)
	2.19 arcsec/pixel (at f/6.35)
Filters	B, V, R, I, Schott BG20
Operating temperature	-5 to -30 degrees (water cooled)
Autoguider	656 x 495 pixels (each 7.4x7.4um)
Focus mechanism	Finger Lakes Instruments Precision Digital Focuser

Zoom Lens Spectrograph 2

A successor to the Zoom Lens Spectrograph originally used for spectrscopy prior to the 2013 upgrade. This instrument is still in development but details of the original can be found here and in this paper.

CCDSPEC

This instrument was a collaborative development between the UBO and Elliott Instruments.
