The Leo Trio and Chertan in the constellation Leo

Managed to grab 4-hours of data last night on the Leo Trio region with the bright star Chertan (Theta Leonis) in the field of view.  This is a very quick and nasty process by yours truly – Noel will do a much better job.  One piece of good news – I managed to rid the optical train of a mess of dust bunnies which had accumulated.  Turned out they were on the face of the CCD chip itself and luckily I had some proprietary polymer lens cleaner to hand to remove the little bu***rs 🙂

I should mention that in all these recent Sky 90 images I am using the CCD in portrtait mode – so north is to the right in these landscape mode portrayed images.
