Equipment and Imaging Details:

• Apertura AD10
• Celestron X-Cel 2x Barlow
• ASI676MC
• ASICap
• Gain 290
• Frames at 0.65ms
• Manually tracked for 4 minutes and 22 seconds, stacked top 20% of 36 frames that were close in time (due to the rotation/orientation changes of the ISS during the pass)

Processed in PIPP and AstroSurface (stacked, increased gain, and sharpening)
