Thanks Kelvin for the nice photos.

I was equally impressed by the two 12.5 inch dobsonians and RLow's 6 inch wolf in sheep's coat. Next time I should bring my 10 inch f/6 dobsonian for its second light.

The first set was sold. The second set (serial no. NrXP0172) has slightly lower specs (RMS 0.017 lamda, PTV 0.14 lamda) and one tiny nick on dew shield. I could offer it at $ 1750 only.

Thanks for looking and Happy new year!
