Perfect, the exact sizes I needed


@Birchall_2756 Glad it worked for you! Thanks for posting the make! Looks nice!
Great job, it works like a charm! Printed on 0.15 mm Structural in PLA on a Mk4. I got a nice sharp pattern on Sirius on a clear winter night, in a Bortle 8 area; it made fine tuning focus super easy. Recommended for anyone with a Hadley. (edited)
