Nice choices Brett, Camelopardalis is a favourite constellation so have seen these two often :)
Telescopes: 1 more than I need but 2 less than I want
Mounts: 3 Equatorial, 3 Az/ Alt
Diagonal: 3 mirror, 2 Amici, 1 Herschel
Eyepieces: Likely more than 1 person requires

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!

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
