ODK16rangename

The ODK16 is in use world wide by amateurs and professionals alike.

Viewing the spot diagrams and other graphic information below will show you just how good the ODK16 presents it’s outstanding specification. As wil all the ODK models we don’t skimp by using just 2 lens elements in the corrector system, we could, but we know from extensive computer designs that there is a real need for 3 elements to give a wider, flatter field. It costs quite a bit more to have this extra lens but, if you compare like with like spot diagrams of an ODK with a similar model on the market, the difference is noticeable and, it’s there for every image you take or visual observation you make, you have the best optical performance available in an Optimised Dall Kirkham, anywhere.

We recommend that ODK16 are observatory mounted, ideally on a Paramount but, other mounts are available and we will be pleased to quote you for these if we do not offer them here on our web site.

Optional Dew Shield available - this is a matching, lightweight carbon fibre addition to help curb the onset of condensation in damp prone atmospheric climes. It is fitted or removed literally in less than a minute and greatly reduces the heavy dew precipitation which can so easily ruin what could be a classic imaging session.
