Entering co-ordinates into EQMOD

Recommended Posts

I seem to be struggling getting the co-ordinates right in EQMOD :embarrassed:

Mine are N 53.XXXX,E -2.XXXX

Do I enter it as -2 and select E or do i enter it as 02 or just 2 and select W??When i select a target in CDC it either points in the opposite direction or at the floor :grin:

I've tried all manner of variations,none of which seem to work?

Any help much appreciated :cool:

I assume you mean your home coordinates? In my Eqmod window there are specific boxes for the site information a box to choose latitude N/S then a box needing two digits for hours, same minutes, same for seconds, then below that a box for longitude E/W then boxes for hours mins and secs like above. You don`t need any decimal points or + or - points anywhere.

You also need to ensure your coordinates in CdC are identical to those in EQMOD or things will go a bit wrong!

Thanks for the response chaps,in CDC my co-ordinates are lat 53.XXX and long -2.XXX so how would input that into my home co-ordinates?

Go to Setup>Observatory and enter your coordinates, Degrees and Mins are straightforward, seconds have to be xx.x format (ie seconds and tenths of seconds). Then name your observatory and click Add. If you find your site on Google maps go in as far as you can and right click, click on "Whats here?" and you get the decimal coordinates and a little green arrow. Left click the tip of the green arrow and you get coordinates in dd.mm.ss.s format.

Thanks Roger, I've done that bit,my problem is how do I enter a -2.XXXX co-ordinate into EQMOD ?do I select East -2.XXXX or do I select West and enter 02.XXXX or 2.XXXX?

If you are in Manchester then you are West of Greenwich. Set up through EQMOD set-up and enter degrees mins and secs. Each is only two characters. You also set N/S and E/W. There is no need for +- signs. You also need to set your elevation, I'm not sure how critical this is (Unless you live up a mountain!).

So i should set EQMOD to W 02.XXXX? But in CDC the long is -2,shouldn't they both be the same?Unless I'm missing something fairly simple?

Which version of CdC are you using? - the latest is v3.8. With that version you simply enter long and lat with N/S and E/W choice. No + or _ signs needed. Therefore you need your long and Lat in Degrees, minutes and seconds rather than decimal degrees for both pieces of software.

You don't, you enter degrees, mins and secs along with the N/S E/W choice, using the EQMOD set up screen. You need to convert your 2.xxx (which is decimal degrees) into degrees, mins and secs. If you look back to post 5 I explain how to do it using Google maps.

This is where it's getting confusing,to enter a east -2.XXXX I must select West and input 02.XXXX?

It wouldn't be east -2. The minus/plus sign denotes the direction either side of the meridian. So you can have 2 deg west or 2 deg east which is the same as -2 or +2. For example: Manchester (from google) = 53.4800° N, 2.2400° W. This is equivalent to 53 deg 28' 48" N / 2h 14m 24s W. Obviously you'll have to be more specific when you enter your observing location.

Well i've entered the lat/long as suggested by Stu but the scope still moves in the opposite direction to the target i've selected,this is doing my head,it must be something I've missed in EQMOD somewhere?

Perhaps its an aussie import :)

Assuming you are selecting the right mount when connecting via CDC then I don't know what to suggest. I'd check the time and location entries are identical in CDC and Eqmod. I notice you are using a modified mount. Has it worked for you previously?

Lol,I'm selecting Ascom mount in CDC etc,CDC time set to use 'system time' and EQMOD says LST?Can't see in EQMOD where it displays the correct time?

As a quick check you could open up the CDC clock which shouuld be in your start menu > programs> skychart/CDC. Then check to see that these correlate with eqmod. Other than that I would wonder about the mod. Am I right in thinking you would've needed a synscan type board for the mount mod? If so, maybe wires are crossed/soldered incorrectly?

Check that your PCsystem time is correct and that EQMOD and CdC times match it. I was caught out by a wrong PC system time a while back.

Do i set it to LST/BST/UT time etc??The AstroEQ needed to have the motors reversed so hopefully that's that fixed!!

How do I match the PC /CDC time with LST time as shown in EQMOD?

Thanks for the replies

You could locate the meridian RA in CDC and assuming all the settings are correct that should if i'm not mistaken be your local sidereal time shown in eqmod.

You don't they are two separate things, just make sure your PC time is correct.

Local Sidereal Time is the RA value associated with meridian line. EQMOD calculates this using the current PC system time and you site details - it is displayed for info only and is not directly settable.

Hi,

Just a thought.......

If setting lat & long manually is proving to be a problem, you might consider getting a GPS dongle (Maplins do them). EQ Mod can take co-ordinates straight from the dongle.

      Hi All
      Has anybody else had this problem?
      I use a single, ageing laptop (HP620 8Gb RAM) running Windows 7 Pro 64bit to control my imaging setup using the following software;
      Cartes du Ciel and EQMOD to control EQ5 Pro mount via EQDIRECT cable connected via powered USB Hub
      BackyardEOS to capture images from Canon 450D via same USB powered hub
      PHD2 for guiding using GP-CAM 130C and EQMOD pulse guiding
      What confuses me is that some evenings everything works absolutely fine.  Another evening, using exactly the same hardware, software and even connections (ie I always plug the leads into the same ports) the system will be working fine but then suddenly fail.  The failure affects EQMOD indicating a timeout or port not available issue and the Canon 450D also 'locks' requiring a restart of the camera and BackyardEOS.
      I have run USBTree during such a failure and it is showing that the EQDIRECT cable (ie serial converter) is still connected to COM4 (which is correct) and the Canon 450D is also still connected.  I basically have to ensure that all the software is closed and any associated services also stopped.  Of course, the scope is now pointing away from its home position so I have to move it manually back to 'home' before starting again.
      My thoughts are that there could be a number of issues;
      1. Use of a USB hub
      2. A dodgy EQDIRECT cable
      3. USB cables too long (ie about 5m)
      4. Windows is turning off a connection (I have set the power management for each USB port to 'off')
      5. Canon 450D somehow 'freezing'

      When using this laptop, I turn off the Wifi and Anti Virus and Automatic Updates are also off.
      It just baffles me that sometimes this system works flawlessly for hours and yet other nights it keeps failing.
      Any suggestions gratefully received.
      Thanks for looking.

      I am at a complete loss to understand why eqmod was not syncing on CdC last night. I have had a look at this video, I had the star centred on the screen [3m33s], I pressed sync on CdC, I got the dialog box [3m39s], I clicked 'yes' and NOTHING happened: the white circle stayed where it was, no sync points were added to EQMOD, zilch!
      I can get round most problems, but this really one stymies my GOTOs and, therefore, my imaging process.
      I have been unable to find anything in the EQMOD documentation that deals with such an error and a search on here has turned up no help (but that always depends on the words put into the search!). I checked all the obvious things (location, date/time, etc - but why any of these should stop sync working is beyond me). It's all running on Windoze 10.
      Any suggestions on why this should have stopped working and (more importantly) how I might get it working?
      Thanks.

      I have several parts, motors, and an arduino based AstroEQ controller that I don't use and maybe they could be useful to someone else. Btw I currently live in Turkey and I will ship everything with registered post from here. It should take approximately 2-3 weeks to reach to UK or other parts of Europe. I can accept payments from Paypal and also UK bank transfer.
       
      First, I have the arduino based controller. I have put it in a plastic project box. Pretty much everything is connected by jumper cables and the stepper drivers are on a breadbox. So it would be possible to change the casing or the individual parts rather easily. The DRV8825 stepper drivers are fast decay modded so they won't jump steps with lower voltage motors. I have installed the latest firmware that Tom has put on the website. If you want I can also adjust the voltage on the drivers before shipping depending on your setup. I'm asking £20 for it and £7 for shipping.

       
       
      Next I have two nema17 0.9 degree 6V 0.8A steppers. I have attached RJ11 female jacks for connectivity. £15 each and £7 for shipping. Both of them are sold.
       
       
      I also have a Nema14 1.8 degree 4.6V 0.8A stepper. Again I have put a RJ11 female jack. Price £10 and £5 for shipping.

       
      I've two handmade motor brackets for EQ5 (or equivalent) mounts. One for Nema 14 motors and the other for nema17. I have used the nema17 for RA and Nema14 for DEC. I'm asking £7 each and £5 for shipping.

       
      I have GT2 pulleys and belts. Two 40teeth and two 16teeth. 40s are bored to 6mm and 16s are 5mm, so they will fit the EQ5 worm and the stepper motor shafts. That would make a gear ratio of 2.5. I've included two GT2 140mm belts, which worked with my setup by adjusting the space a bit. I'm not willing to split this as the shipping cost would be more than the parts. As a whole I'm asking for £15 and £5 for shipping. Sold

       
      Finally, I two 2 meter cables with RJ11 jacks. From my experience when the standard thin phone cables are too long sometimes the motors don't function properly. Hence, I've used ticker cables with these connectors. £10 for total of two cables. £5 for shipping.
       

       
       
      If I ship multiple items together it will be cheaper. I'm also open to offers. And please ask me if you need more info.

      Setting up all the software on my win10 laptop and getting things to talk to one another is a nightmare.
      I'm starting a new thread, so I can post all the problems I am having, one at a time, so issues don't get confused. This will also hopefully help anyone coming to similar situations later, as the problems and answers will not be interlaced.
      First issue: APT does not detect ZWO camera.
      I have got the camera (ZWO) drivers installed and sharpcap can see it and will connect to it properly. However, when I try to connect the camera in APT, the only CCD options it gives me are SBIG (which it isn't), QSI (which it isn't) and ASCOM. Now it shouldn't need to use an ascom driver, because the proper driver is installed, but I give it a go anyway, and this just offers me 2 simulators and 3 QHY cameras (I have one qhy driver installed for the guidecam .... I'll get to that later!). I have disconnected both the filterwheel and guide camera from the camera hub, so they cannot be interefering with the process.
      I am at a total loss ... any suggestions?
      Thanks.
