Hi Dave,

thanks for sharing - very very nice. I had a look at the full scale image on Astrobin, as it was interesting to look at the impact at different scales. I ended up preferring the view at about 50% scaling, where the image is still comfortably too big to see it all at once, giving it a sense of scale, but the halving of size just makes things look a tad crisper than they do at 100%.

cheers,

Robin

Very nice. I guess that we have all been busy with the moon recently. Conditions quite good

Thanks Tim. A lot of strong gusty winds from the East up here on the Pennines. Capturing lots of data has helped me 'get lucky'. At ~100Gb captured per hour, I have acquired 0.75Tb of data since 21st April. The unattended stack + decon of BiggSky has made the initial processing easy.

I have been waiting for the wispy clouds to take a hike and now for the winds to settle down... looks like I will have to for the last quarter Moon to get the great relief you all are getting. In the meantime I just keep enjoying the photos you all are publishing...

The trouble with the waning moon is it keeps unsociable hours.

The 10-panel mosaic managed a Top Pick Nomination on Astrobin. Thanks to SharpCap and BiggSky.
