I have continued experimenting from my light-polluted backyard with the Canon 350D (modified) and the Lumicon H-alpha filter and the 200mm f2.8 lens. The latest is a 2 hour exposure of the North America and Pelican nebula area. This is also my first exposure with the new Astro-Physics 400 GTO mount. The mount performed beautifully as expected and I am excited about the data gathered. I have more work to come, so please stay tuned.

How is a 2 hour exposure possible? Is some equipment moving to follow a fixed position as the earth rotates?
