Or to be more blunt, (within the margins of diminishing returns) it's no longer a rich man's game   |
My first astro-camera was a Box Brownie. My mount was half a house-brick. Very steady. A roll of film took eight whopper images. I tried doing really long star trails, and learned about sky glow. Short star trails were better. But when they came back from the chemist, there was no charge, because the laboratory thought they hadn't come out. There was no picture of Snoopy chasing a beach ball. So
very economical.
My next mount I made myself using a motor from a gramophone, some Meccano pulleys and rubber bands, and a piece of half inch threaded rod for the final drive. The counterweight was a pineapple tin filled with the guts from an old car battery. Probably got lead poisoning.
