A Duncan Mask can be used to easily and quickly collimate your SCT.
The mask comes in three sections that "snap-fit" together and can be taken apart for easier storage (C5 and C6 are one piece).
Feel free to contact us if you do not see your scope listed.
Printed in durable, temperature tolerant PETG filament.

See the INSTRUCTIONS.
