catman161 Posted April 7, 2013 Share Posted April 7, 2013 Very nice paul. Great colour and so many stars resolved. Good stuff! Link to comment Share on other sites More sharing options...
dawson Posted April 7, 2013 Share Posted April 7, 2013 Gorgeous. I really need to get a better mount. What is the fuzzy structure at about 2 o'clock near the edge of the image? Do you do something to make the bright peripheral stars have that cross on them, or is that just a pleasing artefact; i like it. Great.

Antares_Paul Posted April 7, 2013 Share Posted April 7, 2013 Tremendous effort Paul. It's funny - when I first entered the imaging fray my 'thing' was planetary nebula but over the course of time the images posted here have opened my eyes to the full beauty of the night skies. You have done this particular globular cluster great justice Regards. Link to comment Share on other sites More sharing options...

The bright stars show diffraction spikes caused by the spider in the newtonian scope. Some like them and others may not. Link to comment Share on other sites More sharing options...
