Hi All. I have just got a Star Analyser 200-F as Ken suggested trying
to find setting distance between Analyser and CCD, put
all info in to Grating to Sensor Calculator and to keep
all settings green it is between 57mm and 25mm so do I
set it at 41mm which is*1/2 way between, my settings are


TELESCOPE APERTURE 254mm MEADE 10" RCX
" FOCAL RATIO 8f
SEEING 3 ARCSEC
STAR ANALYSER 200
GRATING TO SENSOR 57mm* down to 25mm
CAMERA PIXEL SIZE 6.45 STARLIGHT XPRES H9C
" CCD WIDTH 1392pixels " " "

if you need any more info let me know.
