The Lunt LS100THa pressure tuned 100mm f/7 714mm and the Lunt 100mm DSll/LS100THA filter with a 12mm blocking filter. The internal pressure tune etalon and the DSll filter allows ~<0.5 Angstrom bandpass. I use the Lunt 7.2mm-21.5mm zoom eyepiece for viewing, and the PointGrey (Now FLIR) Grasshopper 3 IMX174, this is a 2.3MP and up to 163 fps camera I use for solar imaging. Focusing is done with the Starlight Instruments HSM30 This is all sitting atop the Astro-Physics 600E QMD mount with an Astro-Physics tripod, . .
