Starry night photography having fun with f stops

Hi all, I've been continuing my experiments with astrophotography using my EOS Canon 70 D and the results are becoming better and much sharper. Here are my latest #longexposure photographs.

I started with the ISO set to 100, f/4 and an 8.5 second exposure for this first shot of the moon and as you can see it is a little blurry and quite blown out.

Next image below was ISO 100, f/4, 43.9 seconds.

Next image ISO 100, f/1.4, 14.9 seconds

The next image settings were again ISO 100, f/1.4 and 17.6 seconds using the Sigma 30 mm lens

Final image settings ISO 100, f/1.4, 16.1 seconds exposure. Again with the Sigma 30 mm lens

As you can see hopefully. The images got progressively sharper at f/1.4 and now it's a case of making smaller adjustments to select particular elements that you want to photograph in the night sky.

I'm having a lot of fun with this and got a couple of clean photos of the moon but they came out tiny like these below?

I don't know what I did there but they were just super small? You can see the craters of the moon if you squint lol

Have a peaceful weekend folks.
