Now the
Rothney Astrophysical Observatory
Baker-Nunn telescope was never designed for colour imaging (the imager is buried deep inside the telescope). So to do colour, we use theatrical gels large enough to cover the entire 0.5m aperture. We then get the R, G, and B channels from that. (eye contact in one pic)

For those joining #Mastodon from Twitter, Facebook, Instagram, etc. things might seem quiet at times and not as active when you first join.

Remember that no on here is collecting your data, building a profile of you, algorithms trying to keep your attention to sell ads, and you are not a product.

In a way the more time you spend looking for people to communicate with, replying to toots, and boosting toots will connect you with more people.

Also remember use a couple hashtags once in a while for things you're interested and excited about.

Although right now my posts are heavily -related, that’s only 50% of my passions, the other being ! Actually, the latter is a byproduct of getting clouded out too many times while trying to do the former! My favorite game genres are games and , with a notable exception being on (6 years and counting).

@Cityspsceastro hey thanks for the follow! Glad to get more enthusiasts in the platform 😀

@stux do they accept PayPal or a similar alternative? That could be a workaround...

So it seems is back online... still a bit slow but I can refresh my news feed without getting an 502 error.

Another #introduction tip for new Mastodon users ( like me ):

Unlike Twitter, which shows strangers' posts in your feed once they get popular or once your friends like them, Mastodon appears to only show you posts by people you're following and posts they've boosted ( which is Mastodon-ese for RT )

So if you appreciate someone else's post and you also want your followers to see it too, you need to click those boost arrows. Just clicking the fave star won't make it visible to your followers.

@spacetides I don’t mind the 🧵, it gives me the opportunity to ask questions to specific posts 😅. However, the character limit is server dependent, in my case my character limit is 65,535 (!). Not that I intend to write that much!

@spacetides @dpthorngren an interesting and related side topic is the Roche limit, which establishes how close a satellite can get to its planet or other massive object before the planet’s tidal forces acting on the satellite overpower the satellite’s own gravitational attraction. In other words, following the same example, the planet would disintegrate a satellite that gets too close to it. See: Saturn’s rings (?), Phobos’ future.
