The imager was an SBIG ST10XE through a Takahashi TSA102 reduced to f/5.98. It was guided with a Meade DSI Pro II through a piggybacked Celestron Onyx 80ED. The mount is a Takahashi EM11 Temma 2 GOTO Jr.


This image is the core of IC 1805 "The Heart Nebula". It is a monochrome image shot through a 13nm Astrodon Hydrogen Alpha filter. 9, 10 minute subs aquired in Maxim DL. False color added in Photoshop then the Ha image was layered again as luminance. The "frilly" detail reminds me of the fractal created by the Mandelbrot equation.
