Double Exposure on a single frame of 35mm film... Building exposure first with 300mm FL at f5.6 for one second... on tripod.
Shutter is then reset without advancing film... on older mechanical Canon bodies this is acomplished by pressing the film release button and winding the film rewind crank 7/8ths of a turn... then turn the shutter set/film forward lever to the end of it's travel.
After resetting the shutter, the camera was attached to a Celestron 90mm Maxatov-Cassegrain telescope mounted on a "One Armed Bandit" equatorial mount with an adjusted drive rate to match the tracking of the Moon.
Both shots were done with the shutter release timer to minimize vibration... mirror lock-up was also utlizied on both shots.
Processing was done with only MiraPhoto scanner software, 'ScanWizard' presets... no Photoshop work at all... a true 'Double Exposure'... from the start...
(Yo... 'Z'... this is all easy... where are *your* daily 'Chicago Land' astro pix... hUh ?!? )
Thanks all for the nice words and great rating! Taras... the procedure outlined above is the *only* way to achieve a double exposure with these camera bodies. As such... the precision of the alignment of the second exposure leaves much to be desired... you can't excercise complete control of the framing for the latter exposure. Combine this with the extended focal lengths being used... especially the 1000mm FL of the lunar shot, it's hit or miss - pure and simple.
Personally, the ghosting of the spire is what I *like* about this shot... when one takes the artistic approach over the analytical, there can be no mistakes... only happy accidents !!!
Nice individual exposures, but this image would be stronger if you paid attention to the positioning of the elements in this composition. If the moon was not overlapping the tower, this would be an excellent example of a double exposure adding the moon.
