The standard filter size for the 0.9-m is 3x3 inch and 4x4 inch. No other filter sizes available.
There are two filter wheels that can hold up to 8 3x3 inches filters (or 7 plus clear), and one filter wheel which can hold up to 5 4x4 inch filters.
We do have adaptors to allow the use of 3x3 inches in the 4x4 inch filter wheel.
If you are an observer looking for a filter not listed here, there is a chance that it can be lent from SOAR, please contact your Scientific Observer Support.
