Cygnus Loop (full)
I've photographed sections of the Cygnus Loop several times before but never had a telescope and camera that had a wide enough field to capture the loop in its entirety. The Dwarf III in mosaic mode finally gave me that capability.
I captured this image two ways to create three different iterations. First I took 200 subframes 15 seconds each using the Astro filter built into the Dwarf III. This is good for representing stars without bloat. It does not do a good job of revealing detail in nebulae. Next I took 200 subframes 30 seconds each using a Duo filter. This filter is good at revealing nebulae details, but tends to produce stars than are not terribly sharp.
I first tried combing the results of both filters, but I didn't particularly like the result. Neither did I like the result of the Astro filter. The Duo filter produced the most pleasing image to my eye, which is what is posted above.
