<QuinnDunki> @a2_4am @scanlime First rule of having a shopcat. Everything you need is always behind, under, or inside the shopcat.

Also consider what happens if a pen gets inside the cat.

It could mark up the mirrors or lens!

<egg|zzz|egg>
GreeningGalaxy: I think anything deep-sky isn't really visible unless I get very close to the window (high altitude)
<egg|zzz|egg>
GradingRaptor: but Jupiter is cute
<egg|zzz|egg>
yeah, it has bands at times; not very easy to see though
<egg|zzz|egg>
also it's now out ow the tree
* GradingRaptor
blames the window.
<egg|zzz|egg>
GradingRaptor: ok, in the 2.5 I definitely see some banding when it comes into focus
<egg|zzz|egg>
problem being that the image wobbles in and out of focus all the time because atmosphere
<egg|zzz|egg>
probably because of air currents inside the room from the window rather than outside?
<egg|zzz|egg>
not sure

<egg|zzz|egg>
I'm in a city
<egg|zzz|egg>
and I'm looking at 35 deg alt
<egg|zzz|egg>
GradingRaptor: mind you the 2.5 mm eyepiece is definitely pushing this scope to its eggstreme limits
<egg|zzz|egg>
GradingRaptor: not in terms of magnification per aperture, because short focal
<egg|zzz|egg>
but in terms of chromatic aberration and focuser precision etc.
<egg|zzz|egg>
it *is* a finder after all :-p
<egg|zzz|egg>
just a very fancy finder

Any Jovian cows?
<egg|zzz|egg>

<egg|zzz|egg>
Europe
<egg|zzz|egg>
GradingRaptor: ah no, Zeus turned into a bull
<egg|zzz|egg>
(to abduct Europa)
<egg|zzz|egg>
GradingRaptor: ah, Io was turned into a cow
<egg|zzz|egg>
GradingRaptor: well, clearly a job for the bovine observatory

GradingRaptor: though the whole tuco flyer project is about making a wire-suspended camera+lidar+whatever thing that swoops around to track the cat...
<egg|zzz|egg>

<egg>
UmbralRaptor: done
<egg>
UmbralRaptor: note on the penultimate image (Kerbin-centred, sun-aligned, long duration) that the orbit does precess in a way, but not around the pole; it's just that Kerbin is tilted
<egg>
and as the precession is around the pole and not the normal to the eggliptic it does that
<egg>
(I could probably tune it more, but the general pattern due to the equator not being the ecliptic is eggspected I think)

whitequark: have a couple of cfgs for Kopernicus + Principia with a tilted oblate Kerbin and an oblate Jool (no tilt aside from Kerbin because then I'd have to mess with the orbits of the tidally locked moons and I'm lazy). It also puts KSC at 40 deg. lat. so there are seasons at KSC. https://drive.google.com/file/d/0B4y-shYXMH9Bcm9Uems0blR2NWM/view?usp=sharing
<egg>
whitequark: note that this requires Kopernicus as well as principia, because with principia only the gravity models will be read, the system will be hashed and found non-stock, and nothing will apply the retrobop correction to prevent the apocalypse.

one of the FETs on the board doesn't seem to work or something
<egg>
whitequark: so you send this in a plain text email, and then you get ephemerides for the bodies you requested
<egg>
whitequark: so if you ask for a long ephemeris for one body that comes in one email
<egg>
whitequark: but it comes in one email per body
<egg>
whitequark: and here we want an initial state, so we get one email with 6 numbers we care about, per body
<egg>
that's about 30 emails getting sent at the same time, which generally takes some time (maybe gmail is rate-limiting?)
<egg>
then we have to parse that madness, which would be easy if they were all in one place, but here it's 30 different mails, so we dump them into a file with google takeaway and awk the thing
<egg>
whitequark: now arguably asking it for one point and using that as an initial state is not ideal; the data that comes from those ephemerides is fitted to observations, sometimes derived from analytical models, and isn't always suitable for integration
<egg>
the "proper" way to do that is to tweak your ephemerides to get a best fit of observations
<egg>
but, well, fitting VLBI data is not on the yak stack nor on the bikeshed heap yet
<egg>
whitequark: oh, HORIZONS also has an interactive interface
