Sun in white light. Full disk plus close up of sunspot region June 17 2025
Dataset consists of a full disk raw TIFF at F7, a close up raw TIFF of the sunspot grouop at F28, and the respective finished JPGs. In both photos I used the TEC160FL with a Lunt 2" herschel wedge and a Player One 7.5nm 540nm photosphere filter. I used a Baader 4x telecentric with a Saturn SQR-M 533 camera for the close up. Seeing 3.5/5
