Clear night but half a Moon blazing away.  Never mind there’s a nice long 6-minute pass of the Space Station due at 22:35.  In fact for the next week there are 6-minute passes due every night!

I didn’t notice a bad stitch in the original data.  This is a 4-pane mosaic using the Canon 200mm prime lenses and Trius M26C OSC CCDs.

An unusual grouping had me out last night with the Canon 5D MkII and 15mm Canon fisheye lens.  It was 10:30 p.m. and still fairly light outside (darkness doesn’t start until Midnight!).  Vega, Arcturus, Spica and Jupiter provided the Quartet, and as Ursa Major was directly overhead – I grabbed that one as well.  10-second (bulb) exposure at f#4.0 and ISO 400.

This is last  night’s data taken between 11 p.m. and 12:30 a.m. on the Sky 90 array.  18 x 10-minute subs, and a star has been labelled for reference.  One bright asteroid in the FOV only clear in the averaged data.

Thank you Tom How of the Curdridge observatory for identifying the mystery asteroid at far right-centre as 729 Watsonia.
