" Whilst we were awaiting the delivery of the 80lines/mm diffraction grating from China, Jolene in consultation with Kurt, decided to design and fabricate a 100lines/mm spectrometer for mounting after the objective lenses on the JPO refracting telescopes and before a ZWO mini mono camera, which we had available.
As she was beavering away in the Clean Room, there was a knock on the door and the postman delivered the eagerly anticipated Chinese Grating. Less than a week in transit. Excellent service and thank you!
When we complete these projects, the JPO team will be able to use the Seestar S30 for stellar Spectrometry at 50 and 80 lines per mm. and the 66mm. and 127 mm. refractors at 500 and 100 lines per mm." - Joel Cairo CEO of the Jodrell Plank Observatory.
