Stellarium - select star by galactic coordinates

Recommended Posts

Hi,

is there any way to select stars in Stellarium (I'm currently using 0.15.2 version) by its galactic coordinates? 

If it's possible, I need to select the stars that are as nearest as possible to the galactic equator and at 0º, 90º, 180º and 270º longitude (and 0º latitude). 

 

Thank you for advance

HI, 

I tried to do what you want by going to the sesrch menu,  then clicking on position and then choose galactic,  but after we enter the coordinates it just centers the screen on it. 

I guess the easiest way is to go the sky and view,  markings,   choose galactic grid,(you may want to uncheck equatorial grid to avoid too much things showing on the screeen) mark galactic equator, then do a search like mentioned above and select the stars near it  by hand.

HI Treta, this is the way I was working currently, but I found it not very exact... Thanks anyway

 

Maybe I should submit as a request for the next Stellarium version or update...

That would be a nice feature.  

To be more accurate you may use ocular view after you choose the stsr near the coordinates you want.  This way will show plenty stars near the regiion.

I'm not sure I understand what you want to do.

But I recently learned how enter RA and DEC settings by copy and pasting them from The Sky Live into Stellarium slew control (The telescope icon on the bottom).

Then click 'Slew to' and away it goes.

I've gotten really excellent results doing that.

Are you tried the enable visibility of galactic grid and use zooming to solve the task?

Yes. It was the first approach to select the nearest star to this galactic coordinates. But it'll be very useful to have a tool or something to select a star by coordinates.

Hi SoonyE,

the telescope icon from the bottom isn't for changing the type of mount from equatorial to azimuthal and backwards?

No, no it isn't for EQ/AZ, that is toward the left in that lower menu.

The Telescope Icon is for telescope control. When Stellarium is used to control the mount, allowing to select a star or object, then slew to it. When Stellarium is used for control, in that window there is a place to enter RA and DEC coordinates for direct slewing to those coordinates.

I fairly strictly run in EQ mode. But occasionally I do use the EQ or AZ grid display.

OK, I see where the confusion lays... you are referring to the first Telescope Icon (#11 from the left.), while I am referring to the second telescope Icon (# 20 from the left.). Sorry for the confusion.

 

Maybe more clarity could be found here.

I went into the Left window of user options, Configuration window (The spanner wrench symbol), then under the i (Information tab), in the Displayed fields, right column, make sure Galactic coordinates is checked. Check it if not. Then restart Stellarium and see if it helped.

Sometimes the devil is in the details, and I mention this from my own struggles getting Stellarium tweaked into what I have now. Why just yesterday, Cosmic Geoff helped me update my catalog of Comets. So my own use of Stellarium is still evolving, you see.

I'm still using Stellarium 0.15.0 version as I prefer it. But then, I preferred classic Windows to the end.

We are a bit like chickens. If we keep pecking at something, pretty soon we got all of it. Or at least our fill... :wink2:

I'm not using Stellarium as a telescope controller, only for calculations purposes. (using Stellarium 0.15.2 and all the stars DB downloaded).

 

As you can see in the attached image, I've found a pretty close star to the point I was looking, but there's no name for the star, so I cannot get the proper motions and so on for my calculations. Even the other stars in the view have no name. Any idea how I can get the name for certain stars and the look in Symbad or another online star DB.

Well, I guess not. I, too, have my Stellarium as loaded as is practical for me at this point. All Star databases.

I did find a java script converter, took your coordinates, and got in the area with Stellarium. But mine took me to a void in Stellarium.

So I think what you are seeking, I'm not finding. I do know there are a lot of stars out there that have not been named, or cataloged.

Perhaps that is what you have come across? Maybe the above converter can be of help?

I have a workaround for you: you can put an custom "objects" in the place with some galactic coordinates and use them for selection.

Never thought of that. But, how I can do that? I mean, create some custom objects and put on selected coordinates for testing.

Just try press Shift button and click left button of mouse on the sky. Some details available in Help window (F1).

P.S. We might add scripting method for add/remove custom objects by galactic coordinates.

      Hi guys,
      With new mount and upgraded scope features, now looking to venture into imaging.
      Before I start, I'm not looking to get feedback on polar alignment, mono guidecam, better imaging cameras, etc; this is more a 'dummies guide' setup discussion! I'm not expecting to get great images at this stage, just more the options available, getting over some issues, so that I can jump outside on a clear night with an ideal, foolproof(!), setup for either imaging or visual as time would permit and what may work best for me. As you may guess from the topic name, I'm a mac user (Macbook Pro) and would rather keep to this if possible (whilst I do have Windows (and Ubuntu) via parallels, I'd rather not use these).
      I've got a setup which has worked well for visual, and obviously want to have a couple of 'staple' setups that I can use depending on expectations of night observing or imaging. So far, the best one for me has been the Skywatcher Wifi Synscan controller, which has worked a treat with my Android phone - I use the Synscan app to complete alignment and GOTO stars/planets/DSO etc, or Stellarium_plus after completing alignment. This removes the need for the Synscan Handset and any USB cables to the mount altogether. But I don't know if this will work for guiding.
      That then brings me to my issue on mac - connecting USB(A) between Macbook and Handset, I've attempted to control the mount through Stellarium. Trying each of the available connections (/dev/tty.usbsetial-1420, /dev/cu.usbsetial-1420, and just for sake of it, the /dev/tty.Bluetooth-Incoming-Port and /dev/cu.Bluetooth-Incoming-Port) in the dropdown menu under DeviceSettings/SerialPort, I cannot get the mount to connect (well, more like selecting the telescope and clicking the "Start" on the TelescopeControl just results in the spinning icon and I have to Force-Quit Stellarium and start again with the same result each time. Annoyingly (for fellow mac users!), Parallels/Windows/Stellarium connects and controls the mount fine! As the mount is the newer "pro" type, I also have a USB connection directly under the hand-controller RJ45 and AutoGuider ST4 sockets, but using this still results in the same issue. Another issue I have seen is that when I unplug the USB from the computer when connected to the handset, the date on the controller jumps significantly - for example, last night at ~23:30, I was transported through the local wormhole galaxy to Jan 2048 according to Synscan! Obviously unplugging isn't going to happen during a genuine session, but just wondering if this is a possible issue somewhere?!
      Any other mac users connecting USB directly to the SW 'Pro' mounts?
      Software wise, would folks generally suggest steering away from Stellarium towards KStars or SkySafari(Plus) for controlling the mount?
      Can the Wifi dongle be used for controlling mount from computer (any OS) or do I need to go USB either to handset or directly to mount?
      Is there an issue in using Mac USB to the telescope compared to 'straight' Windows (i.e. PC/laptop with Windows instead of virtual)?
      Anyway, back to topic... I've a Nikon DSLR to use for primary camera at this stage, which would be triggered independently from guiding software. PHD2 is my hopeful choice of guiding software (is EKOS with KStars similar?), with T7C guide-camera on 240mm f/4 guidescope, and at this stage, I can confirm PHD2 at least connects to the camera on OS-X. There is an ST4 port on the camera, but having read several topics, I think I want to pulse-guide directly - is this correct or is ST4 best for this setup? This sorta comes back to software and connections - my understanding is one of the following cable setups for guiding (as a minimum) :
      Guiding-camera => USB(A) => Macbook => PHD2 => USB(A) => SynscanHandset => AZEQ6
      Guiding-camera => USB(A) => Macbook => PHD2 => USB(A) => AZEQ6
      Guiding-camera => USB(A) => Macbook => PHD2 => Wifi => SynscaWifi Adapter on AZEQ6
      [using ST4: ST4_on_AZEQ6 => Guiding-camera => USB(A) => Macbook => PHD2] (no additional connections needed if ST4 is used)
      Additionally, I'd like to use an observatory package, say Stellarium/KStars/SkySafari, to select objects and drive the mount, then use guiding software to keep good 'tracking'.
      Where in this train does EQMac fit in, or when is it used?
      What about the 2019 addition to EQMod (ASCOM Alpaca)? Can this be used or is it already in other packages?!
      For Windows users, how does EQMod fit in (if I go down route of getting Windows laptop for controlling things, is the setup similar to above?
      There may be bits in the above that repeat, and for that, I'm sorry, just want to get across the message that I'm new to the guiding but haven't quite settled down into the software/hardware I'm expecting to use for 'goto' and 'guiding'
      TLDR:
      For a mac user, what setup and software are folks using for guiding and observatory softwares for the newer USB-on-mount 'AZEQ6/EQ6-R Pro' mounts from SW?

      I'm trying to set up Stellarium with my cameras (Canon EOS 1300D and a Canon EOS 2000D) and my telescope (Celestron NexStar 127SLT). I think I've found the correct values for everything like focal length and sensor size etc... but the FoV in Stellarium it is different to what I actually see. I've attached screenshots of the settings, as well as the predicted image and an image I captured using the EOS 1300D and the Celestron NexStar 127SLT (it's not very good, I know).
      Any help would be much appreciated. (And I apologise if I've posted this in the wrong place - I'm new)

      Today we published a fresh weekly snapshot of Stellarium (v0.20.2.18140): https://github.com/Stellarium/stellarium-data/releases/tag/beta
      And we need some feedback from users. At the moment we need to know your opinion about changes in 2 plugins - Satellites and Oculars. Of course we'll accept your opinion about changes in other parts of the planetarium too, but those 2 plugins in our focus.
      Thanks for your attention and testing.

      I've always used the web version, but since I got the telescope I decided to install the full desktop version. I managed to save my setup and eyepieces etc.
      Things that I unable to save and not sure whether I should be able to:
      - start in Windowed mode
      - fixed both settings and viewing bars bottom left corner
      - Object information - I set my 'Customised' options, but after relaunching the app they are lost_
      - basic stuff like date format, start-up time (default to 10pm)
      - I think I can say that NONE of the Configuration [F2] settings save
      - Sky and viewing options window [F4] - NONE of the options changed here save between sessions
      The only thing that saves is .. my location.
      Am I missing a plugin, some sort of trick to save those, should I reinstall or does Stellarium simply not save these F2 and F4 settings between sessions?

      Hi SGL,
      is there any plugin or setting that can (more) accurately depict views through an eyepiece?
      I'm aware of the oculars, but what I'm after is the shimmer of the planets, dimming of DSOs when using smaller scopes, planetary detail dependent on telescope size etc.
      Thanks
