Meade DSI pro II and a 10-inch LX200 Schmidt-Cassegrain Telescope.
This image is a composite of many images taken @ f3.3 and 6.3. For the filamentary structure a number of unfiltered 2min exposures taken @f3.3 were heavily pushed with levels and unsharpening filter in Photoshop, then subsequently combined and wavelet processed in Registax to bring out the detail. This enhanced filamentary image was then combined with the single best image. The inner detail was taken with 1min exposures @f6.3, scaled down and combined. Similar techniques were applied to red and H-alpha data.
