Here is the first image taken with my new 120 mm Frehel achromatic and diaphragmed 100 mm sunglasses allowing me to reach an ideal F/D 10 ratio for observation with a standard PST modification on February 24, 2023. The Fabry Perot standard comes from an old 2005 PST Coronado telescope that I have just recovered and transformed with various optical filters. I then installed inside the telescope, a Lumicon rejection filter for the 77 mm aperture Halpha allowing increased contrast and a black background of the resulting image. This construction is perfectly complementary to the 150 mm Halpha telescope and well suited to turbulence depending on the observation conditions.© Andre cassese
