[09:54:12] <Ingar> Pluto moves into the sign of Aquirius!
[09:54:30] <Ingar> with a typo, but I'm still recouperating, so I don't mind
[09:55:11] <chromas> Getting some new photos?
[10:04:03] <Ingar> chromas: I was making fun of an astrological event :-p
[10:04:16] <Ingar> with the l of lalalala
[10:04:37] <chromas> oh yea; I didn't really read the message right before yours; I assumed it was nonsense :)
[10:05:11] <Ingar> coincidently, I am updating my pi
[10:05:24] <Ingar> 't seems the arch linux package is out of date (wtf)
[10:06:55] <Ingar> I might get some clear sky tonight but there's moon and I'm still not feeling great
[10:07:54] <janrinok> I have a huge rain cloud covering me at the moment, and it is slowly moving your way...
[10:08:42] <chromas> connect() to it and see if it's storing any goodies
[10:09:19] <Ingar> it's the french cloud strategy

[11:26:31] <Ingar> update seems to have succeeded
[11:26:42] <Ingar> I can photograph the inside of a lens cap!
[11:41:31] <janrinok> Ingar, you must have quite an extensive collection of lens cap photographs by now. Do you think they could be the next thing on Tik-Tok?
[11:53:54] <Ingar> janrinok: jokes aside, "dark frames" are a thing
[11:54:28] <Ingar> you take a bunch of them, stack them to even them out and you get a baseline noise level which can be subtracted from your image
[11:55:02] <Ingar> black level calibration as it were
[11:55:19] <janrinok> understood - a nice idea
[11:55:21] <ted-ious> What do you use your raspberry pi for?
[11:56:03] <Ingar> ted-ious: it runs my astrophoto setup
[11:56:25] <ted-ious> So like a robot controlling the telescope mount?
[11:56:28] <Ingar> the telescope mount and the cameras are connected over usb
[11:56:37] <Ingar> ted-ious: exactly
[11:56:38] <ted-ious> Oh nice usb cameras too.
[11:56:47] <Ingar> the best thing is, it has a timer
[11:56:52] <Ingar> so I can program it and go to bed
[11:57:03] <ted-ious> So you can get the images straight into a computer instead of having to go to a card?
[11:57:13] <ted-ious> Ooh very nice!
[11:57:29] <Ingar> ted-ious: the rpi is on my wifi, so I grab my images over ssh or smb or whatever
[11:57:54] <Ingar> messing with sdcards is for the young
[11:58:05] <ted-ious> :)
[12:04:08] <Ingar> http://ingar.intranifty.net
[12:05:51] <Ingar> the local console is mostly convenience because I was messing around inside anyway

[12:28:11] <chromas> needs moar cables
[12:30:05] <chromas> Ingar: so the main and spotter scopes are both usb cams?
[12:38:16] <Ingar> chromas: indeed they are
[12:39:18] <chromas> Maybe I need to start stargazing. I don't have a decent view here at all, but it's another place to spend some money :D
[12:40:14] <chromas> the light pollution isn't too bad here, other than a street light right next to my yard, plus I'm surrounded by view-blocking trees
[12:40:50] <chromas> Speaking of fab23's link from the other day, I didn't even know Cyrus has a mail server. I just know the name from their SASL thing
[12:42:58] <Ingar> stargazing is fun
[12:43:13] <Ingar> the easiest way is to just go outside at night and try to name constellations
[12:44:36] <chromas> Cup, cup, strap, big dot, little dot
[12:44:48] <chromas> and of course, W
[12:44:55] <Ingar> :D
[12:45:17] <chromas> or possibly M, depending on your perspective
[12:45:27] <Ingar> afaik kinda sideways these days
[12:45:59] <chromas> ∑
[12:46:15] <Ingar> casseopea
[12:46:19] <chromas> sideways recognizer
[12:46:21] <Ingar> wasn't she the chick chained to the rock ?
[12:46:27] <Ingar> or was that andromeda
[12:47:06] <Ingar> *cassiopeia even
[12:47:07] <chromas> I never remember. was it the same rock the guy had to keep rolling uphill like a linux distro?
[12:47:25] <chromas> or did they have more than one rock back then?
[12:47:33] <chromas> I just assumed they all shared
[12:47:54] <Ingar> that was Sisyphus Torvalds
[12:48:17] <chromas> I remember looking up the woman who turned people to stone once and discovered there were a few
[12:48:36] <chromas> I guess if languages can borrow then so can stories
[12:51:03] <ted-ious> Medusa had a sister?
[12:51:51] <Ingar> Margareth Thatcher
[12:51:57] <chromas> https://www.youtube.com
[12:51:58] <systemd> ^ 03The National Orchestra of the UKOG - The Life of Sillyphus
[12:52:10] <chromas> Seems like one was a pair of sisters
[12:53:58] <chromas> In Final Fantasy 13 Shiva is two sisters and for their ultimate summon thing they get together and become a motorcycle
[12:54:12] <chromas> I came up with the name Scissor Sisters, but it turns out that's an old pop group
[12:54:21] <chromas> ghey disco
[12:58:41] <Ingar> and the worst of it, I recognise one of their songs
[12:59:11] <Ingar> time to quit the internet!
[13:09:20] <chromas> You don't quit the internet; the internet quits you
[17:22:01] <Fnord666> Ingar: Do you control the motors on the mount directly or does it have a built in controller and you just send Ascension and Declination commands to it"
[17:22:06] <Fnord666> ???
[17:22:34] <Ingar> Fnord666: it has a controller, you can also use a handcontroller box if you want
[17:23:13] <Ingar> at the pc end, it's a serial-over-usb connector
[17:23:37] <Fnord666> Gotcha.
[17:24:13] <Ingar> you need driver software and all that
[17:24:30] <Fnord666> Of course.
[17:26:28] <Ingar> the next stage is to hook it all up to a powertank so I can go portable :D
[17:28:05] <Fnord666> It would be nice to be able to take it to a dark site.
[17:28:49] <Ingar> very
[17:29:33] <Fnord666> Alignment fairly automated?
[17:29:48] <Ingar> polar alignment is manual
[17:30:45] <Ingar> at the start, that was a bit of a hassle, but you get the hang of it
[17:30:58] <Fnord666> Understood.
[17:31:06] <Ingar> the software helps though
[17:31:16] <Ingar> it points arrows to the direction you need to turn the knobs
[17:31:25] <Fnord666> Having a camera on the spotting scope probably does as well.
[17:31:39] <Fnord666> Oh that's pretty neat.
[17:31:49] <Ingar> the spotting scope is for guiding
[17:32:02] <Ingar> once airborn, it tracks stars
[17:32:10] <Ingar> and moves the mount accordingly
[17:32:41] <Ingar> it's the key to long exposures
[17:32:49] <Fnord666> Oh that's cool. Everything I've ever used just follows a preplanned path.
[17:32:51] <Ingar> (expensive gear helps too ofc)
[17:33:01] <Fnord666> of course! :)
[17:33:48] <Ingar> I've been at it for over a year now, step by step
[17:34:04] <Ingar> there's too much crap going on to do it all at once
[17:34:33] <Ingar> and you need to become a pro with gimp color -> curves
[17:37:22] <Fnord666> I'm very much a casual observer and hadn't actually got into astrophotography other than a basic mount that I can attach my DSLR. No tracking though so it's just for things that can be imaged at 1/30th or faster.
[17:38:04] <Fnord666> I've looked into more serious gear but as you said, it can add up quickly.
[17:38:41] <Fnord666> We've had so much development around me that whatever I did would have to be portable to a real dark site also.
[17:39:43] <Fnord666> Apologies but I have to run an errand. Back later.
