| Jul 8, 2020 at 10:34 | comment | added | Saaru Lindestøkke | @Dan I'm a bit confused on the 200 seconds max exposure time. My understanding is that the raspberry pi camera has a max. exposure time of 10 seconds. I could've misunderstood the documentation though. Can you please point me to a resource that explains how I can get the 200 seconds exposure time? | |

I’m tempted to do it, though don’t know If I need any more cameras. Allowing to miniaturise equipment is beneficial and reduces cost for everything substantially, since you’re already running Pi you could potentially do autoguiding with a webcam attached to whatever optics you decided on. Only if it wasn’t limited to 200 seconds. | |
| Jun 20, 2020 at 9:46 | comment | added | Dan | Same optics, different camera. To get equivalent detail you’ll need obviously a much greater focal length which comes with much greater expense for the lens or telescope and also the camera, slower f-stop to deal with (which could end up better), or also vs same cost. I’ve used old 70s lenses - 50mm and 200mm on my A7s and also on a thieye T5e (imx117) and get incredible detail out of the 50mm which is around 300-400mm equivalent, and 200mm as well, though 200mm has some optical issues with fringing when image is enlarged that much | |
| Jun 19, 2020 at 1:34 | comment | added | scottbb♦ | you’re going to get a lot more detail out of it due to magnification. I think I see where you're heading, and I'm not sure I agree. What do you mean by 'magnification"? And when you say "get a lot more detail", more compared to what, exactly? A different camera? Based on the same lens, or the same field of view -equivalent lens, or... ? | |
