    That's a good question, the effective magnification. Very high, I know that. But the situation is different, because you can view the image at different sizes and distances, I'm not sure it even applies. I have not researched these issues.

    The lens has been removed, so some kind of objective lens is needed. Any lens projecting an image will work. Telescopes are best for astrophotography, I'd like to experiment with a microscope as well.

    The batteries I used were purchased from 5 Below, which no longer carries them. Batteries are changing, I'd look for anything larger capacity so I don't need two. Check this out - Qualcomm Certified Quick Charge 3.0] Poweradd 20100mAh Portable Phone Charger Power Bank with LED Display (Amazon). The display is Elecrow HDMI Display Monitor 5 Inch HD 800x480 TFT LCD Display for Raspberry Pi 2B B+ Raspberry Pi 3B with Touch Screen.

    What's TV? ;-)

    Yes, this is "toy" code just to try it out. I already shot myself in the foot with several times. I'd like to have an actual app for this.

    Thanks! Never heard of a CIS, I'll have to check into this.

    Thanks! Amateur astronomy now has many possibilities that didn't exist before.

    Excellent suggestion! We teach kids to make videos, maybe we can get them to make one for us.
