Description

Object Name: NGC7293

CLS/Ha/CLS/OIII

70/60/70/60 minutes

My first attempt of the season on the Helix. Roughly an hour per channel before the moon light became an issue. I will try to double the exposure time in the following days and get that extra red nebulosity on the very edge of this unusually large planetary nebulae.
