<e_14159> So, the workshop I'm currently reviewing for has two tracks, with different requirements (mostly page lengths). But there's apparently no indication which paper has been submitted to which track?
<raptop> If the people running the workshop like the papers, they go to one track, and hate them the other?
<e_14159> It's published/deployed methods and future work ideas, respectively.
<raptop> Published in papers, and published in grant applications
* raptop <_<
<e_14159> I mean, I can pretty much guess from the content, but that's not how it's supposed to work
<e_14159> First track is even called Papers. Second future work, though; not grant applications. Would be a good title, though.
<raptop> I guess it's now a suggestion for future workshops
<raptop> iximeow: I'm struggling with some stellar identification (specifically if the star that appears to be at the center of M 57 is in fact the central white dwarf)
* raptop wonders how hard it would be to get some aperture photometry done with the campus telescope
* raptop ponders grabbing stellarium or something?
<iximeow> ooo
<iximeow> that sounds fun
<raptop> ...obviously this means get a grant to buy ixi a fancy CCD and set of Johnson UBVRI filters
<iximeow> yes

<raptop> eg: both of the brighter stars in M 57 in this image are visible with our telescope, but is central one the WD? https://www.nasa.gov/feature/goddard/2017/messier-57-the-ring-nebula

* raptop has questions for the green owl
<iximeow> what a nice picture :(
<raptop> ...why :( ?
<iximeow> i can't take pictures like that :(
<raptop> To be fair, that was taken with a 2.4 m telescope. In orbit
<iximeow> give ixi a 2.4m orbital telescope
<iximeow> actually give ixi a 4.8m orbital telescope
<iximeow> more airy disc
<raptop> Give ixi a 6.5 m telescope (if IR is okay)?
<iximeow> i'll acceptit
<raptop> well, poking at simbad and aladin suggests that the central star is the WD?

<raptop> hat's quite an acronym

<raptop> WeylandsWings: I'm immediately reminded of how much setup and troubleshooting a lot of goto scopes have
<raptop> I mean, waterproof and USB charging seem like nice things (ditto phone control, but I'd hope that it also plays nice with windows/linux/osx machines)
<raptop> huh, 50 mm f/4 apo
<raptop> IIRC, a 200 mm f/8 SCT with similiar electronics is ~$2k?
<WeylandsWings> eh you can get a 6" go to celestron for 700
<raptop> s/f\\8/f\\10/
<raptop> huh, cheaper than I thought.
<WeylandsWings> no camera tho
<raptop> ...why do they keep on describing bad things as "defaults"?
<e_14159> raptop: BGR for openCV, anyone?
<raptop> ?
<SnoopJeDi> OpenCV's preferred color model is BGR
<e_14159> openCV defaults to BGR for images instead of RGB. Every project I've done with it, I forgot about that until I looked at images and everything red was blue (which is surprisingly hard to notice, actually)
<raptop> hah
<SnoopJeDi> it's all over the place in computer vision
<raptop> Hm, nominally 3"/pixel
<raptop> Airy disks would be ~5" across with that, so probably all the resolution you can get
<raptop> Someone is going to be annoyed that they can't resolve the double-double
<raptop> Pros of system: can output FITS, low read noise. cons: tiny pixels, probably RGB restricted, 12 bits per pixel
<WeylandsWings> cons tiny aperture
<WeylandsWings> cons reliant on the software put out by that company
<raptop> yeah, I should have typed sensor, not system
<raptop> And also, costs are $1-4k, so you're not saving much (if anything)
<egg|cell|egg> Whitequark: The templated code point was evident to me (Principia!) but the compilation speed point I had not thought of, I should consider that https://mobile.twitter.com/whitequark/status/1314651199359135747
<WeylandsWings> raptop: i was just thinking if you got a 6" celestron at 600, plus TheSkyX Imaging (which has the auto calibration though TPoint Addon) at 500, all you need to add is a camera (that can be controlled by TheSkyX) and you would have a much better set up at about the same price
<WeylandsWings> and there are plenty of decent inexpensive astro cameras
<WeylandsWings> and i mean if you are looking for something more than those cameras or performance you arent looking at a 2k ish set up, you need to be looking more at a 10k set up
* raptop would consider a backyard observatory a major reason to buy a house >_>
<WeylandsWings> me too
<raptop> o_O
<egg|cell|egg> Quadrature of highly oscillatory functions whose evaluation is ill conditioned is hard
* raptop is going to assume that egg has strapped a piece of toast (butter-side out) to the back of a cat

<WeylandsWings> Oh raptop scope alignment question. Why would a certain mount manufacturer want to to roughly align to Polaris then choose another star within 5 deg to center with the azel adjust before going into a super detailed alignment routine? Mount is an equatorial
<raptop> Unsure, I'd have to guess something to triangulate on the north pole?
<raptop> ...guaranteed circumpolar star?
<WeylandsWings> But if you don’t do it is so weird because you can get lucky and your alignment will still work or unlucky that alignment will fail
<WeylandsWings> Maybe we just grabbed a really bad star
<raptop> dunno
<raptop> This is one of those things, where there is a clear reason, but unless one could see the source code or something...
