Clear night here tonight. I've printed a Cartes du Ceil star chart for UV Cam, the brightest of the three, but still on the edge of my visibility range!

Regards

Graeme

Fairly sure I found UV Cam using my 11x70 binoculars placed as it is adjacent to the Jolly Roger Cluster! The colour didn't stand out as well as I hoped at magnitude 7.5 and the just past full Moon not too far away. I'll have another go when I get the telescope back up and running! The cluster will make a good target too!

Thanks Brett.

Regards

Graeme
