Orion Optics UK ODK Dall-Kirkham Astrographs

Orion Optics UK ODK Dall-Kirkham astrographs are corrected Dall-Kirkham telescopes, with a corrector lens that gives a flat field for large imaging sensors. The line runs from the ODK10 to the ODK24Tr, in closed tube versions such as the ODK10, ODK12, ODK14 and ODK16, and truss versions from the ODK10Tr to the ODK24Tr.

They are long focal length instruments for galaxies, planetary nebulae and small targets, and suit permanent observatories. Atlas focuser cell adapters are also part of the line.
