Filters
Look for filter information on the INGRID page:
http://www.ing.iac.es/Astronomy/instruments/ingrid/ingrid_filters.html
Position in telescope
INGRID can be used on two positions on the WHT telescope
- Cassegrain focus F11 beam
- Nasmyth focus (behind NAOMI) F16.5 beam
Aligning
Documents of the aligning procedures:
