Sunspot AR 2529

After deassembling the focusser on my Orion XT12 I could reduce the focus point for my Nikon D60. Before it was always necessary to install a barlow x2 to reduce the focus point. The picture below is thus the first picture taken without barlow x2. The picture was taken in RAW and edited using CS4 (curves & levels spectrum).
