Lovely view Rob
I love Ha images and Eta is always a great target in Ha!
The 100% crop does look just a tad soft though, I know it wasn't the scopes fault that's for sure

....was the seeing poor? Maybe focus? Perhaps it could handle a bit of sharpening..?
What's the seeing like at Wiruna generally?
I am going to Wiruna next weekend and have allocated myself 3 nights to hopefully get lucky as far as the weather goess..? Looking outside at the moment and reflecting on the last 2 weeks....I'm scared
You going to Wiruna?
