NGC 281, the "Pac-Man Nebula"

This image has coused a lots of trouble to me. At one point I was thinking what's the point of doing this!
Let's face it, my equipments are a big pile of crap. Everything is faling a parts and I'm spending more time to fixing things than actually imaging.
It's not a picnic to spend two hours outside and soldering when it's very windy and temperature drops to -26 celsius. (-15F). I really need better instruments if I'm going to continue this "hobby" (read addiction) now everything is put to gether from self made solutions and cheapest possible parts.
Ok, here is a image after all, not a perfect one though. I started this project at the end of the last month and I collected last photons 16.12. I collected 42 x 1200s of H-alpha light, that's a 14 hours.
Due the technical problems I was able to use only 6 x 1200s, Two hours, of them!
