Andromeda Galaxy

Here's one of the first test images with the Levenhuk 80mm triplet. It is 53 X 300 second (4.4 hrs) subs at ISO 800 with the Canon T3. Using the Astro Tech 0.8X reducer/field flattener the field of view is 3.2 degrees wide X 2.13 degrees high with the image cropped to 98% of the original.

At an apparent magnitude of 3.4, the Andromeda galaxy (M31) is one of the brighter Messier objects, making it visible to the naked eye on moonless nights even when viewed from areas with moderate light pollution. In this photograph M31 appears more than 6 times as wide as the full moon. Only the brighter central region is visible to the naked eye or when viewed with binoculars or small telescopes.

    This is an absolutely stunning image of M31/NGC224 and the two companion galaxies M32/NGC221 and M110/NGC205. There is a lot of fine detail in the spiral arms even to the core of the galaxy. On close inspection of the full resolution image the galaxy M110/NGC205 reveals a hint of detail also. Very well done Rich!
