Mmm. Yes I must try a dew shield. Don't have one as yet but if this solves the problem it's a step. I didn't mention that there was a street light that was shining just into the scope but this is a orange lamp not blue ? Also the issues doesn't appear in shots I did of the Orion Nebula. It only appears when a bright star is in the shot ?
The other thing that still bothers me is that I have about 4 shots of Altinak (orions belt) that have a similar issue. Now when I animate through those shots the anomoly rotates around a virtual centre along with Altinak ?
I'm off down the coast for a few nights and I'll take the Meade and check out the same areas and stars to see if the same issue happens. This will at least remove the street light from the equation.
Thanks again to all for some leads to dealing with this problem !
Cheers,
Steve R.
