M31 High Resolution Mosaic

The following image of M31 is a mosaic of 40 separate greyscale frames taken from

September to November 2002. Color data for the mosaic came from previous images of M31

I took over the last few years using various short focal length instruments.

Cumulative exposure time for the entire mosaic was 50 hours.

Each greyscale frame was imaged at a focal length of 2000mm and

had a resolution of 1.7 to 2.5 arcseconds depending on sky conditions.

The equipment used was a 12.5" Ritchey Chretien Cassegrain (at F6) and ST10XME.

The mosaic was assembled using Adobe Photoshop 6.0

 

This image was selected as one of the greatest astronomical images

of the last 30 years by Astronomy Magazine, September 2003
