Please ensure proper comet tracking. Comets move faster than stars, which currently results in stars remaining round while the comet appears streaked.
Enyaalex Nothing to ensure. Seestar can't track comets or asteroids.
How long your exposure time?
About 10 minutes
Enyaalex I'm referring to the exposure time for a single frame image.
Tech@ZWO 20 seconds
Enyaalex The longer the exposure time, the longer the comet tail will appear. Try using a 10-second exposure.Use Alt/Az mode
