Thank you for sharing your photos - this is exactly what this project is all about! :-)
Testing a new lens. The result is decent, the background is terrible, but it works for capturing M51.

Good lens. Perhaps ISO 400 and a longer exposure will reduce the background noise.

Well, I'm still inexperienced at this. Plus, on the first night, there was humidity and the focus was a bit off. But I liked the lens.
