M33 - Pinwheel Galaxy in Triangulum

M33 is visible by naked eye under very dark and transparent sky conditions and very easily observed through binoculars. It is 3.1 billion light years distant and approximately 60,000 light years diameter. Although it is large and has a very bright core (+5.79 Mag), it is actually difficult to completely image because of the fainter outer arms of the spiral galaxy. The galaxy has many star-forming H II regions which are imaged in this astrophotograph. Method: Takahashi TOA 130 reduced to 754mm, f/5.8; Astro-Physics 1100GTO; Aluma 694 camera. LRGB data: 8 hours.
