Description

A rare successful bi-color image for me. Televue np101is with .8x reducer and STT 8300 with Baader Ha and OII filters. This is a drizzled image and is 4x the size, so full resolution mode takes allot of time and is a bit too much.

Ha 18 30 min
OIII 23 30 min

Subsequent versions (1 at the time of this note) emphasize the soap bubble as much as I can manage .
