Talking A Galaxy from Video - NGC 253

Bored due to excess Moonage last night. I put the Mintron video camera into the SN-8 at prime focus and let it store video into the camcorder for half an hour. Here's the result. Focus and polar alignment was rough and I didn't capture enough dark frames to reduce noise, but it's not bad for a moony night. A fair bit of detail shows through - more detail than I can get with my DSLR at the moment.

Scope: Unguided LXD-75 SN-8" Astronomik CLS filter
Camera: Mintron 13V1C-Ex
Exposure: 650 frames (x128 integration) = 27 Mins approx. AGC Manual Max. Gamma 0.45.
Process: Recorded to a Camcorder then captured and stacked in a PC by Astrovideo. Curved, masked and unsharp masked in Photoshop.
