But in all honesty you only ever have a problem on the brightest stuff.... Try m45 and you will see what i mean.
Simplest way to test is just go and target the brightest star around and remove any reflective surfaces until you have a winner. Keep in mind it could be reflecting of the actual CMOS chip in the camera .... You cant remove that .
I wouldn't panic. It is as rob says common to have reflections, I've seen rgb images with three different colored halos around this very star due to reflections from the filter surface http://www.iceinspace.com.au/forum/a...se.php?a=83606
I only put this up to show how easy it is to get them and it's also a very similar composition as yours.
Again don't panic about it 99% of the time you will get nothing. |
Thanks again for the reassurance and advice Clive
I'm really not concerned about it now that I know it wasn't really my fault and as you say won't be an issue 99% of the time. It's the first time I have ever come up against a really bright star, so I thought I would pose the question. Prior to this I think the brightest star I have come up against in the field of view is the one next to the Orion Nebula

Well done.

Thank you so much for that lovely feedback Brent. I'm glad you like it.
Don't get me wrong, I love how this turned out and I am very proud of it. Will certainly be gracing my wall soon. I was more curious as to weather it was an optical train issue or weather a lapse in my setup had caused it.
