OBJECT DESCRIPTION

Messier 33 is a member of our Galaxy Local Group along with Andromeda and our Milky Way. It is the third largest member after the two mentioned. The Galaxy contains remarkable spiral arms which are rich in star forming HII regions. Although the image has no Ha sequence shots, the regions were brought up easily. The most remarkable area is NGC 604 which is one of the largest HII regions known.

The Galaxy was very however I was willing to shot this object for a long time. Very difficult processing: More data will be added in coming seasons.
