That's a tiny one, only 90 sec arc across. Well done.

A smooth image with good colour and saturation but it looks like it is a tiny bit out of focus. I could be wrong. What was the seeing like during imaging?

Nice one, Wayne. As Mike said, it's only tiny so quite a challenge.

Thanks Mike, Paul and Rick, yes Paul the focus was good but seeing very bad then clouds moved in that's why I gave up after only a few hours of imaging.

Always one of my favourite planetaries this one and it's a nice shot but as others have said it does look a bit soft. I don't know if the dreaded deconvolution would help.

Cheers

Steve

Considering how you captured this little bugger unguided and derotated alt az (was than via a mechanical de-rotator or just software?) I recon this is a great result, all the main structures are discernible, nice sense of scale to the object and the colour is vibrant.

Of course being quite small seeing is everything
