荷兰采购需求：投影穹顶、穹顶投影屏幕、天文馆、天文馆穹顶、穹顶天文馆、金属投影穹顶

I'm looking to purchase an astronomical dome with a diameter of around 5 meters for our school. Ideally, it should come with additional telescopes and equipment to ensure it's fully functional for educational purposes. Can you provide me with details on the available options, including pricing and delivery timelines? I'm based in Russia, so any information related to shipping would also be appreciated. Feel free to contact me at my phone number if you need to discuss anything further. Thanks!
