Notes (S00088)

- 1 hr 50m imaging session  (June)
- Night skies in June in Aberdeenshire don't become astronomically dark
- The observing session was an attempt to see what could be seen in June.  
- Whilst the observing window is small (local midnight +/- 1 hour) and there arent' too many stars to see with the naked eye, I hope the following images show that it can see be worthwhile to go out with a telescope even in middle of the Scottish summer.
- Seeing quality was excellent, with FWHM levels down to 2.5 arc secs (the best seen for months)
