The ODK Series
ODK10
From: £3,915.00 excl. VAT
The introductory model for the ODK range is our 250mm model, the ODK10. As with all the ODK models, the ODK10 is fitted as standard with our ACU-3S, 3” focuser to enable a strong focusing platform for a wide range of cameras. Being both a photographic and visual telescope you are assured of some spectacular views of the planets, the Moon and even faint nebulas and galaxies.
Full specification is shown here on the right but if any feature you are interested in is not shown, please ask.
You will see from the spot diagrams that the ODK10 produces very tight, well defined images. The field size is usable to over 50mm ensuring you have the choice of some higher power imaging and views on axis for the planets and moon etc but also, the capability to present to your camera some amazing fields of Deep Sky objects, particularly those requiring a higher degree of magnicication.
