It’s been a while since my last blog post. During this past year, I’ve built a few other cameras yet released on this blog. In the meantime, I have been looking into options to make this work available to fellow amateur astronomers as a viable product. One major blocker here is the cost. FPGAs are expensive devices due to two factors: 1. They are less produced compared to ASIC and still uses state of art silicon process. 2. Massive area dedicated to routing and configuration logic. Let’s look at a simple comparison. The MicroZed board I’m using cost $200 with dual Cortex-A9 core clocking at 666MHz. This contrasts with quad core Ras Pi 3B clocking at doubling frequency. And it only cost $30.
