What kind of sky image am I seeing on my monitor with the DSS7+ST402? A mirrored image (left to right) or a mirrored and inverted image? It is necessary to know the orientation to be able to identify stars in the FOV of the DSS7 + ST402 using a CGE14. Thanks for any advice.
Here is some archived information on the DSS7 below and attached. DSS-7 Specifications and Comparison to SGS Alan Holmes 9/7/2004 DSS-7: Input F/number: F/10 Dispersion: 5.4 Angstroms per Pixel Projected width of narrowest slit on CCD: 25 microns Resolution with 9 micron pixels (ST-7): 15 Angstroms Spectral Range (ST-7): 4130 Angstroms Blur in Direction perpendicular to slit: Approximately 25 microns Lower resolution slit choices: 50,100, and 200 microns SGS: Input F/number: F/6.3 x F/10 Dispersion (high resolution): 1.07 Angstroms per Pixel Dispersion (low resolution): 4.3 Angstroms per Pixel Projected width of narrowest slit on CCD: 18 microns Resolution with 9 micron pixels (ST-7): High = 2.4 Angstroms Low = 9 angstroms Spectral Range (ST-7): High = 820 Angstroms Low = 3290 Angstroms Blur in Direction perpendicular to slit: Approximately 100 microns Lower resolution slit choices: 72 microns Relative Sensitivity of DSS-7 to SGS for dim extended objects near H-alpha: 5 to 10X I hope this helps.
