From the album: Soleil Halpha lunette 120 mm et 80 mm
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
