Get a #solar H-alpha scope of you're really into #astrophotography. It's an investment, but it gives you something to do when the weather isn't favorable for dark sky stuff. It's a slightly different skillset to learn and will keep things varied.
Plus, the sun is really fucking awesome. Especially for the next few years as we hit the solar maximum. The sun is different every day you look at it. If you're lucky you might catch a flare or some other transient event.
