andrewluck Posted November 25, 2012 Author Share Posted November 25, 2012 I see you're in Norfolk. Pay us a visit some time. We have a twitter account (@breckland_astro) which we try and update whenever the observatory is open.Andrew Link to comment Share on other sites More sharing options...

andrewluck Posted November 25, 2012 Author Share Posted November 25, 2012 Now there's a thought . The 20" is not blessed with a huge FOV given it's 2.4m focal length.The answer is, possibly. However, being an Alt/Az scope causes some issues associated with frame rotation. Images taken at different times will have the diffraction spikes pointing in different directions. You can see this already in the image in this thread. One of our members does have a project running covering the Veil nebula in postage stamp sized images so it is possible, if time consuming (http://farawaythings.blogspot.co.uk/2012/10/cygnus-supernova-remnant.html). It's not the ideal instrument for this type of object though.I've reprocessed the image to bring out more of the shadow detail.
