Description

Messier 74, one of the most beautiful, but also low surface objects from the Messier catalogue.
Some call it "The Phantom"

I'll not be able to shoot RGB of this object this year. Here a colorless sneak preview of this magnificent galaxy.

The subs are 2x2 binned resulting in a effective 728mm FL.

---

Rev B, added some color. Problems with color balance and burned stars. I'll have to reprocess it or aquire different RGB data

---

Rev C, new color aquisition (200/800 Newt) . Stars are still a problem, but the main structure looks better.
