Description

NGC 7662 is a "blue snowball" but is also surrounded by an OIII Bubble.
The zoomed picture on the right is the short exposures one (ASI 290 MMC and ASI 224 MC color layer). Processed with Drizzle x2 (0,18 arcs/pixel).
The large picture is slightly reduced and some long exposures data is Added.
For the extensions, I used a CLS filter and declared it into the blue layer as there is no Ha in the bubble.

Enjoy.
