      I'm here on the invitation of someone else, and not sure what this new website is all about yet/ the space stuff seems pretty scant, so anyone got a question about space they need answering?

      For those who don't know me from the certain other website, I am a radio astronomer currently at the Center for Astrophysics | Harvard & Smithsonian. Known under this user account on a certain other website for comments that begin with "astronomer here!"

    2. Quasar hunting in amateur astrophotography

      I'm not sure how big the astrophotography community, if any, is on ~tildes but I'd figure I'd open a topic up and see! Astrophotography is one of my hobbies, and it was brought to my attention (see link for two quasars near the M3 globular cluster) that it's actually pretty easy to photograph quasars. The same are visible in my attempt at photographing M3. Anyway, my question here is does anybody know of any particular interesting or distant quasars to photograph? I assume most will just be "dots" but it still sounds like fun since they're among the most distant objects you can see. I assume most quasars would be broad spectrum, so no filters are really needed, but I'm also curious if there's any bright yet redshifted objects you'd need infrared to capture.

      My setup is an Astro-Tech AT80EDT 80mm Refractor f/6. I just got the f/0.8 reducer which I'm excited to take for a spin. It's a chonky piece of glass. My camera is a ZWO ASI585MC which does decent enough for deep sky.

      Edit: To add, using something like http://simbad.u-strasbg.fr/simbad/ is great for finding interesting objects once I've already taken a photo, but it's less helpful to plan my shots.

    3. Shooting Stars as a Service - Japanese space entertainment company ALE will provide on-demand shooting stars for your event

      I was watching my favorite weekly space show on YouTube, TMRO, and I learned about Astro Live Experiences (ALE.) They will soon launch two test satellites which will be able to provide a burst of 30-40 man made shooting stars at a prearranged time and place, for a fee.

      Japanese company ALE is the first "space entertainment" company of which I am aware. The only event in the same ballpark was New Zealand based RocketLab's Humanity Star which caused a large amount of controversy. ALE's initial technology will allow a 200km radius of earth to see their multi-color shooting star show. According to the interview on TMRO, in the long term, they are planning to allow image rendering and even artificial aurora.

      This type of business seems inevitable as we advance into space. I can see some benefits and some downsides to this technology. What do you all think of this?

      Maybe this topic belongs in ~misc
