Preparation for Second Piece

I briefly mentioned the basis of my next piece during the first class, that it will focus on my great grandfather as an astronomer. I previously posted this photo, but here it is again:

Since I began looking through photographs, this has been one of the most intriguing for me. When I first saw it, I didn't know what was happening in it and I had to ask what the spider web-like formation was. I was told by my great aunt that, because there wasn't a lot of room for a garden at their duplex in Chicago, so my great grandfather would string up supports and grow morning glories on them. Around seventy years old, he would climb up on the roof to string up his flowers perfectly. I find this photo very visually interesting and have been wanting to use it somehow.

More recently, I was looking through the photographs and I noticed the radial symmetry of this "web," and it reminded me of my great grandfather's hand crafted moon chart. This is a cardboard structure that he made to locate the moon on any day of the year, and it is circular.

I knew I wanted to pair these two... The moon chart will not sit directly in front of the photo, it will likely be attached off of one of the sides. I have vectorized the chart and am hoping to screen print it on a circular piece of plexiglas. Chinn, I do have a question about illustrator, how do you create separate layers from the same vector? I'm thinking of doing a grey layer and a black layer so it looks like this:

As for the panel with the photograph, I am going to choose a relevant constellation to sit directly above the radial pattern in the photograph. On the back, I am thinking about using some raw data written by him concerning the planets.
