Paul and I took the ODK12 to Orion Optics in Newcastle upon Tyme to be refurbished, we arrived there at 10:00am and it was ready by 2:00pm, the time between was spent looking for a place to have lunch.
We were 'dealt with' by Barry Pemberton, founder, who let me look through it in their test bay. He also told me the setting dimension I should use was 210mm and not 209mm as appeared in their instruction data sheet.
We brought her home and loaded her to the mount quite easily, rebalanced and hoped for a clear sky that night, but it was not to be.
