strange halo in pic

[Guest ben72]

hi all,

after the weather we've been having,i decided to set up and blow a few cobb webs off the kit with a couple of test shots of the seven sisters, just for framing and to check all is well.

sadly it looks like i need to adjust the spiders as im getting extra spikes on the stars,but my real issue is the halo in the middle of the shot.

 

it looks to me like a reflection from something but can't narrow it down. 

 

Any thoughts?????
