" The JPO Team was excited to try out the new Lunt Herschel Wedge and set up the old Star Adventurer EQ mobile rig using the 66mm ED Altair Astro Refractor and the QHY5lll462c low light video camera to capture data. The weather wasn't perfect for astrophotography with some wind and high level sky haze.
This was very much a trial run with the Herschel Wedge and we were quite pleased with its performance in showing some detail in the sunspots, thermal convection cells and faculae.
We are looking forward to trying the 'wedge' on the JPO's large 127mm refractor. I have asked Jolene our engineer, to design and manufacture an aperture reducing cover for the big refractor's objective lens as the 'wedge' can only work safely on telescopes having a maximum aperture of 80mm. We believe that with the aperture limited to 80mm and by using a x3 amplifying Barlow lens in the light train, significant improvements in enlarged sunspot detail will be achieved. Watch this space!" - Joel Cairo CEO of the Jodrell Plank Observatory
