Eastern Veil Nebula - NGC 6992

The Eastern Veil Nebula, NGC 6992, is a cloud of heated and ionized gas and dust in the constellation Cygnus. It is a large but relatively faint supernova remnant. The source supernova exploded somewhere between 3,000 BC to 6,000 BC, and the remnants have since expanded to 110 light-years across.  The distance to the nebula is approximately 1470 light-years (source wikipedia).

The entire nebula is too big to imaged with my telescope without a focal reducer.  Visible in this image is NGC 6992, NGC 6995, and IC 1340.  I would not have been able to image this or would have needed many more sub frames last month.  This object is the first I have imaged where my newly modified Canon EOS Rebel T3i (600D). The modification work was done by Hap Griffin at Imaging Infinity. Hap has several options available for DSLR modification. I chose to have the IR Filter Replaced with the Astrodon UV/IR block filter. This modification passes hydrogen-alpha light but blocks IR.
