Limiting magnitude for a 30 cm Ø telescope with S/N 50 and
20 minutes of exposure time.
For the 200 lines/mm grating :
m
v
= 8
For the 900 lines/mm grating :
m
v
= 6
Note:
Measurements performed w. ST-8 XME w. 9 micron pixel
size.
The measured resolving power of the 900L grating was limited
by the pixel matching.
With smaller pixels a higher resolution can be measured.
