M27 20th June 2009

I went out with my Takahashi the other night to do a test of the new focal reducer.
Here is M27, not really a very good subject for a wide field scope, but there are a lot of stars in that area.
This is 19 x 20sec frames @ 800ISO, darks and bias applied, but no flats. I needed a lot more but it clouded over :-(
The focal reducer has cured the star smearing almost, I think the focus could have been a tad better though.
