I have a 900mm refractor - it's a simple telescope with two lenses. I bought a T2/EOS adapter on the eBay , and I installed it to the refractor.
Few days ago I couldn't sleep. The Moon was very bright. I went to the garden and shoot some pictures about the Moon. The full Moon doesn't have much shadows - and we can see the craters, mountains only on the darker side.
The simple lens has a little chromatic abberration - blue border on the right side.
I convert the image in BW - it's highlights of the Moon shapes.
