Is there a MIPI camera that doesn't suck? I have every official Pi camera, and they are all just terrible. I would never use them for anything artistic, when it's easy to get far-superior results from even a cheap regular camera or used SLR. I'm just curious if there's a very-high-quality camera with a MIPI interface. Thinking it through... I only really care about video. Even if it's only HD resolution, something wi…

>Is there a MIPI camera that doesn't suck? No there isn't. Sorry. I've tried them all and their dynamic range sucks so bad.... Anyway, who thinks otherwise, I recommend you see the same non-ideally lit scene with for example a modern "analog" fpv camera like Foxeer Nano Toothless 2 (a starlight 0.1lux camera that maintains it's great dynamic range in full sun). The only mipi camera that has a shred of a chance to com…

Ha, thanks for the reply.

Tangent to your IP-camera comment: I replaced all my old SD, composite household security cameras with cheap-O TVI cameras, and I am impressed at how well this oddball HD format works over the same coax cables.

I really wish RPi would come out with a truly HQ camera.

Their "HQ" camera is really a LOW quality camera with a shitty sensor that isn't even micro-four-thirds. The lens choices are abysmal. I want to see at LEAST APS-C or better yet full frame. Considering a full-blown mirrorless full frame camera costs $2400 it shouldn't cost more than $1000 for sensor only, and I'm 1000% willing to pay for a hackable, programmable full frame sensor especially for night sky photography that can accept the vast variety of full frame lenses already available.

There's the Sony QX1 which comes close to what I want but sadly they didn't continue that or produce them anymore.

Anyone knows how did they make the beautiful diagrams?

He has a bunch of interviews at https://technicalillustrators.org/ (which he co-founded) but I didn't find an interview of him.

On his blog in 2014 he notes in passing some of the tools he uses. https://jamesprovost.com/blog/surface-pro-3-for-illustrators

The camera is good for its price. If you want a MFT sensor, why don't you use something like a Lumix G9 and connect it to the RPi via USB? It's a lot less than $1000 these days.

Slightly off-topic, but did anyone ever run a sky camera with a vision model that recognize what it sees? Like Meta’s SAM.

Plate solving - identifying constellations and deep sky objects by the relative positions of stars - is a pretty common part of astronomy software and possible on a raspberry pi. For example https://github.com/dstndstn/astrometry.net

I'm not aware of anything that can, say, identify a meteor and differentiate it from a plane or satellite, but I'm sure it's possible.

I do think the HQ camera is due an upgrade, though I'd prefer a proper low-light camera, ideally Sony Starvis.

Although you can buy cheap Starvis modules you don't have full control over the exposure time and/or can only shoot in a compressed format. The HQ camera is well-supported with good drivers, like all Raspberry Pi hardware, which is why people still use the HQ Camera for cheap astronomy projects despite having a small sensor and poor low-light performance.

The Pi cameras might seem like a good choice because they're cheap, and might be a good way to start. But with all of the work required to build, install, and maintain one, the cost of the camera is a drop in the bucket. I used a much better camera from ZWO (ASI462MC) for about $300 (I actually ended up building a second one with the ASI462MM (monochrome)). It even comes with an all sky lens. IMHO it doesn't make a l…

For light sensitivity there's an Arducam IMX482 MIPI module. Unfortunately you don't have a lot of control over it and can't take long exposures, but it's probably fine for HD video. Every other cheap low-light module I've seen is hobbled in some crucial way, either at the hardware level or drivers.

I've been in the process of planning a backyard observatory some and have been looking at all sky cameras to measure clouds, seeing and sky glow. This project looks really promising, especially if it has an ascom driver
