Cygnus From Plettstone
This was my first opportunity to try my new AstroTrack
mount. This simple mount replaces a heavier and bulkier GEM mount
that is normally used for astro photos as long as your goals are
relatively short wide field images.
This series of photos was shot using a Canon 20Da with a 24mm fixed
Canon f 1.4 lens (at f/2.8). 10 exposures (120s @ ISO 400) were
combined using Images Plus.
At CalStar I am going to try some photos at 135 mm and see if I can
still get acceptable results. At 2 minutes the individual
exposures were underexposed. More images might help this.

North is roughly to the right side. The texture of the Milky Way is
clearly visible. Several H-alpha areas can be seen in the higher
Having trouble aligning yourself? Maybe this will help

At full resolution you can start to see that this is an unguided
image. Still it is easier to pick out some of the
highlights. In this frame Deneb is about 2/3 vertical and toward
the right of the frame.
