Thanks Mike, Mark and JJJ. My fairy godfather (i dont think he would like being called a fairy

) has indicated I should be keeping my cool soon.
I grabbed 1.5 hrs in 10min subs, but they showed elongated stars as soon as i was off zenith. What I stacked was 2x 7 and 2x 10 min subs. Maybe should have left it at 5mins and grabbed more. I think I was just being greedy

.
In winter it is fine noise is fine, but as soon was the ambient rises above 15deg, noise becomes really apparent.
