Resolution: 1.92 arcsec/pixel
Camera: Vesta 675 SC2
Telescope: 8" F6 Orion Europa Newtonian
Result focal ratio: F6
Exposure: 16x10s (gain 100%, Amp ON), 10xDF
Captured and processed by K3CCDTools
Seeing: thin clouds, lim.magnitude for naked eye 3.3

Very bright (0.93 mag) and very nearby (16 ly) star.
I turned the scope tube to rotate the diffraction spikes about 90° concerning picture from 30.8.2002. The star 32 arcsec west from Altair is better visible now.

5 seconds exposure for comparison...
For comparison here it is a picture from The STScI Digitized Sky Survey.

The red frame shows the area covered by my photos.
The area near Altair is not very well mapped also in GSC catalogue because of high brightness of Altair.
The white frame shows the area covered by my photos.
