Took this picture last week of NGC 7000, The North America Nebula (centre) I was trying to capture this in detail by using a long exposure with the Canon 350D and wide angle lense. The camera was attached to the Celestron SLT mount so that it could be tracked. You can see that the centre is spot on, but then other stars appear to be rotating around the centre. This is because the SLT mount is actually an Alt - Az device, which means that on very long exposures like this, the tracking stays on course but the rotation will be obvious.Exposure time was about 6min. This is a problem with an SLT mount, you can only take images without the rotation up to about 1min.
This makes a lovely image of part of the Milky Way! The colours of the stars in the region are amazing!
I have sent this image to 'Sky at Night' Magazine...fingers crossed!
