 My telescope and camera captures a two-degree field. That's about the width of your thumb at arm's length. I get plenty of detail, but if I want to expand my field of view, I build a mosaic tile by tile by moving my telescope a bit and taking more and more photos over many nights. This is a multi-year project in the constellation Cygnus. I started in 2018 and so far I've completed 24 tiles and I'm currently planning on at least 66 panels. This will be a video series and in the next one I'll talk about color.
