m39 awful newtonian refractor stars

[alacant]

Hi everyone

Really awful stars. With a muddy Mediterranean haze to penetrate, I'm hoping that this along with the 30º ambient and hot dslr to match are responsible. It looks like it's been taken with a refractor:(

Anyone seen this effect before? Cures? The stars from the 10" Newtonian are usually really nice. Disappointing.

Cheers and clear skies.

I have even seen this effect in the Canaries, but not often, I put it down to local conditions, seems to be a heat haze. No cure except to try another night. An image like that in UK skies would be more than acceptable....Dave
