Just wonder if anyone remembers Richard Berry and the Cookbook245 camera. Literally the great grandfather of our digital astrophotography hobby. If not, here’s a starter page I found. http://wvi.com/~rberry/cookbook/cookbook.htm  I was at Astrofest in Illinois when Richard first demonstrated the camera back in the mid 90’s. What a concept, you could use a digital chip to capture objects in the night sky with. Unheard of. We where still using regular film or hypersensitive film back then to capture images. Which by the way was a very long and involving a process called "hypersensitization". Which would lower the reciprocity failure of the film giving you longer exposures. It means unwinding the film in the dark and immersing it in a silver nitrate solution just before the exposure (one could use instead forming gas, needing a specific equipment called a hypersensitization chamber, which required a certain pressure and very accurate temperature control to get it right), and you better not mess it up or you lost the whole roll not to mention the fact that you needed to use it as soon as possible or freeze it to help it last. I was just looking over the work here that can be done today with the equipment we have available and was remembering back to the days when digital photography got started. If you’re not familiar or just wish to reminisce check out the web page and the images that was being done back then. Or just look up Richard Berry’s Cookbook 245 camera.

Very interesting Anthony

Been recently going down the Natalia Road …
have a look at one of the first amateur go-to mounts

My first goto scope was a set of setting circles and I used a radio shack portable computer, the size of an iPhone 14, I think it was 8k, no not 8meg or 8gig, but 8k, and a book that you used to program the computer called programs for astronomers. Punched in the code, basic, then after a month of debugging, you imputed the object R.A. and Dec then it would convert it to Alt Azm then you pushed your scope to the area. So you read the computer and went to the object. This was late 80’s early 90’s.  Oh and it never worked. Lol. That was during the whole make your own scope craze. Then the GoTO craze and now we’re in the astrophotography craze. What’s next the AI craze.

I once build a cookbook 245 camera. It wasn't very good but was a start. The giant leap forward was the Audine of which I built 2.

Never did. Just take a few pics with film. Wasn’t that all impressed with the images and prints looked like garbage. Thought why do that when you can just use film, but that was then, stuff we are getting these days is worlds better than anything the big observatories were getting back in the day.

This is what got me into astrophotography! I traded in a C8 for an 80mm APO and an Orion Atlas so I would have a suitable scope for it. It was a challenging build for sure. I only managed to get one good photo from it—a globular cluster. That night was perfect, and I finally got good focus. Unfortunately the windshield washer pump died at the end of the night. I replaced it with a continuous-duty pump, and it was too much for the seals and they blew out. I was never able to fix it, but when the Nikon D70 came out I got one. It was better in every way but one—I hadn’t built it.

Built a CB245 to use with my C8. Took a bunch of images over several years. This was as good as I could get. Was fun! I certainly couldn't get results like it with film from my light polluted backyard and I couldn't always drive a hundred miles to a dark site so having the CB245 let me enjoy imaging from home. This image is from 2002.
