Processing the Pinwheel Galaxy – Part 1

As mentioned in prior posts, I will be demonstrating tomorrow night ( Tuesday 22nd) at 7:30pm the technique of processing for yourself images which have been taken by telescopes such as the Hubble.

This demonstration is for anyone who is interested in astrophotography but may not have a suitable telescope or camera setup to take pictures of these deep sky objects. It is also for those who have a telescope and camera and want to see an alternate way of post image processing the pictures you have taken through your scope.

If you are interested in attending, please visit the New Astronomers Group (NAG) category section of

For details of where to find tomorrows metting of NAG at the Northern Sydney Astronomical Society, please refer to the map on this page.

Today I will be using this technique to be shown tomorrow to process M101…. which is the Pinwheel Galaxy.

If you look at the image above, you will see one of the exposure files I will be using to process the image taken of the Pinwheel Galaxy. As you can see from this picture, which is the exposure I will be using for processing red colors for the Pinwheel, the picture at this stage looks dark and not particularly interesting.

This of course will change after I have completed the processing of all 4 exposures I havbe for the Pinwheel Galaxy, the result to be seen in the next post.
