Date image was taken: September 18, 2025

Location: Arcadia, Indiana, USA

Data Acquisition Method: Personal Telescope Setup

Description and Details: The two main components of the image, Ha gas (the flowing red folds) and dust (the gecko) are exceptionally faint, requiring just under 100 hours with a broadband filter to capture both at the same time, from August 14, 2025 to September 18, 2025. The results presented well. They are about 1,200 light-years away and glows red due to hydrogen gas ionized by the ultraviolet radiation from the nearby hot, blue star 10 Lacertae.
