Description

Here is an SHO Version with added Sii. Incredibly faint and difficult to keep the noise under control,  but this Helix Nebula gave up some of its inner core detail to my humble ED80! This image is a combination of 115 x 240 sec L-Extreme,  with 24 x 240sec ZWO Ha filters, 40 x 240 sec Sii (12 hours). ASi 533 MC Pro on HEQ5 pro. Processed in Pixinsight.
