I made a video that covers some of the basic steps when first using your DSLR cameras in Ekos. This doesn't go into starting INDI server...etc, just Ekos setup.

New version of Celestron NexStar Evolution driver (0.3) - by: Jochym

I have just released a new version of nexstarevo driver.
There are many internal changes and clean-ups in the code.
Here are the most important ones:
  • Much better tracking performance
  • Always approach from the direction of tracking
  • Telescope autodetection implemented
  • Telescope simulator added with stellarium monitoring connector
  • Dropped dynamical memory allocations in the driver
  • Improved stability (still a bit problematic though)
  • Some code clean up and refactoring
  • Constant approach distance on encoders
  • Periodically update target position on long goto
The resulting driver is much more stable and seams to work better.
This is a stepping stone to more work on polishing the interface and implementing niceties like mount monitoring and setup (battery, lights etc) and extensions like serial communication with the mount (AUX protocol) via hand controller or direct serial connection. This version may be regarded as beta quality and is suitable for careful end-user testing.

For now you need to build it yourself or get it from my PPA (ppa:jochym/libindi-3rdparty is building it at this very moment).
I hope it will be included in the regular nightly builds soon. It was tested on debian on the pc and raspberry pi2.

PPA: launchpad.net/~jochym/+archive/ubuntu/libindi-3rdparty
Development repo: github.com/jochym/indi/tree/nse

I would appreciate any feedback and bug reports/patches.

Two questions on how to implement a feature - by: camielseverijns

Hi, I would like to implement two features but I am not sure about the best approach to this within the INDI framework.

1. My mount supports a meridian swap command. My idea is to add a property to the driver that starts the swap with a push button. How can I best implement this push-button style behaviour? Can I user the INDI Switch property for this?

2. I have developed a automated dew heater. This device also measures the tube temperatures of my imaging and guiding telescopes. I would like to use this information to build temperature compensation in the INDI SmartFocus driver. My idea is to have a single executable implement three INDI drivers: a dew controller and two temperature sensors. The latter can then be snooped by the focuser driver to implement temperature compensation. My second question is how can I implement these three drivers in a single executable?

Regards,
Camiel

Joystick behaviour - by: Kevin

I am using a logitech gamepad as a joystick with an AZ-EQ6 running under the Eqmod driver.
I have just got this going (I am new to indi, having come from the Windows world...) and noticed what I thought was slightly odd behaviour. Thus, when I pushed to mini-joystick paddle in RA, there was a DEC slew as well. I eventually realised that the interpretation of 'right' or 'left' movements (nominally RA) was extremely narrow, and any small component of 'up' or down' in the overall movement was interpreted as an additional slew command. In Eqmod running under Windows, I don't think its possible to combine slews in this way (?). This is actually quite useful ('feature' rather than 'bug') and, while combined slewing is a not a deal breaker, I found it hard to induce a 'pure' RA motion under indi control.

First, do other people find this? If not, is there some setting to manage it? Finally, perhaps there are joysticks out there better matched to the indi driver?

thanks

Hello,
I've installed Kstars on my Raspberry Pi 3 / Ubuntu 16.04.
I also installed the QHY drivers :
sudo add-apt-repository ppa:mutlaqja/ppa
sudo apt-get update
sudo apt-get install indi-qhy
But when I open Ekos, start Indi and try to connect de camera, the connexion doesn't work.
I only have access to a CCD simulator. I don't find the camera.
How do you do to connect a camera and particularly a QHY5 ?
Thanks for your help.

Kstars crashing from slews - by: Ihoujin

I have encountered an issue which causes KStars to hard crash and leaves no useful info in the log. I've so far caused this to happen in two ways what appear to have caused some sort of corruption.
1. Using EQModGUI to move mount
2. Using the Sattracker script from the satellite tracking thread.
After either of those triggers KStars became permanently unstable. It will now crash whenever I make a track target selection in KStars. It does not matter if I am driving my real mount or Telescope Simulator.
Manual slew commands with the buttons from within EKos does not cause a crash.
I have tried reinstalling kstar-bleeding, and found it did not clear up the corruption.
My only recourse at this time is to reinstall my backup image and avoid those initial triggers.

I dont know if it wuld be useful for others but I just tried to simulate my Canon 700D with the CCD Simulator but it seems that SIM_XRES/SIM_YRES is limited up to 4096.
My canon has X res of 5184, so I cant simulate it.

cooling on ASI 178MM cooled - by: patdut

Hello,
I don't know if this is pertinent to open a new thread for this purpose but, I do:)
As I explained in another thread (maybe my remark was lost in a too long message) I met a problem with the ekos cooling management for ASI 178MM-S.
Firstly, the cooling setup (ON or OFF) is not saved in configuration.
Secondly, the cooling can't respect the temperature set: asking -15C and get at least and always -10C with a cooling power never reaching more than 25%.

Apart from this all works fine again. And I am very impatient to test the new polar alignment method.

Kstar crashes on new Lubuntu virtual machine - by: mlarsson

Hi!

I just made a fresh install of a Lubuntu virtual machine on a Win10 host, and installed kstars and Ekos along with the astrometry files. What I experience is a series of crashes, either when focusing or aligning. Not just once, but maybe 10 times. I attach the last kstars log. What to do, what to check with it?

I should perhaps add that I connect to the Indi server remotely, it runs on a Raspberry Pi at the telescope.

INDI/Linux driver for the QHY Polemaster, developers needed. - by: anderslange

Hi Guys

I would like to get my QHY Polemaster camera to work on Linux, in order to use it with the new Polar Alignment Assistant in Ekos.
QHY currently dosn't provide a linux driver, nor do they support the Polemaster via their Linux SDK.

But Qiu Hongyun (QHY) has offered to provide their Low Level USB Protocol specifications, provided I/we sign an NDA.
Read more here: qhyccd.com/bbs/index.php?topic=5718.0 and here: qhyccd.com/bbs/index.php?topic=5602.0

Although I'm a professional Embedded Firmware developer, I currently have no experience in Linux device drivers, nor with the USB protocol.
So I would like to hear if there are anybody in this forum who would like to participate in developing a Linux INDI driver for the QHY Polemaster camera?

I know there are people out there in the same situation as me... who already own a QHY Polemaster, and who would like to use the hardware together with INDI/Ekos.

Best Regards
Anders Lange

OpenCV - by: emk

Hi,

I'm currently writing a little client in cpp to automated evaluate images and check wethere there are satellites in image. I'm using linux, the cameras are an EOS 6D and an ASI Zwoptical 120 color CMOS.
For image processing I'd like to translate the images coming with the newBlob Function of the baseclient as IBLOB structs to an cv::Mat. What the constructor of the cv::Mat needs is a pointer to the start of the image data, not sure if void* blob does that job (?), and the bytes per pixel. Last is in the CCD_INFO NumberVectorProperty, but I'm still needing the void pointer to the binary data. Can I use the pointer contained in the struct or is there f.eks. any fits header i've to consider as well?

By the way, what exatly is in the format string?

Thanks for any help! :cheer:

matching dark frames with linux - by: rkonrad

Sorry that this may be off topic for the forum - but since it's a mainly linux body, I thought I'd ask it.....

I'm trying to find a programme that will accurately match the temperature of my dark and light frames. I use DSS under wine with success. However, the windows, "Darkmaster" which does just this, will not work under wine. Does anyone know of a similar programme for linux?

Thanks!

OBJCTRA & OBJCTDEC keywords - by: psjshep

I managed to finally get all my equipment working with the Raspberry Pi last night, using KStars & Ekos on the Obsy Windows 10 machine - very nice!

What I have noticed with couple of test images is :

OBJCTRA & OBJCTRA are in the format nnn.nnnnnn (which I believe is a TDOUBLE result)

For the astrometry I have done in the past with MaximDL and more recently with PixInsight, the OBJCTRA stored in the FITS header is character in the form 'HH MI SS' (Hrs Mins Sec) and OBJCTDEC is character in form 'Deg Min Sec' (degrees Minutes Seconds)

I was unable to solve any of the images in PixInsight which did not pick up the OBJCTRA & OBJCTRA stored via INDICCD...

Now I realise that the FITS header "standard" is somewhat abused, but at least 3 or the programs I have used expect the RA & DEC to be character long format.....

Comments?

Canon DSLR freezes R-Pi - by: mlarsson

Hi!

I'm experienceing a new strange problem here. Quite suddenly, after having taken hundreds of flats during the day, the Canon 350D starts having problems. I connect, it and take a picture, and get the message "WARNING: Could not wait for event." in the log window. After this the R-Pi freezes and I have to unplug and reboot it. I first believed this had to do with power failures, so I exchange the power connectors. And then switched USB cable, But it doesn't help. Problem seems to be intermittent, though. It was there, then disappeared and then returned when I was going to start on a long series of imaging.... Attached is a gphoto indi log from when the error happened.

Edit: I found out that the log file was quite empty. The log in the INdi console says:

gary@Observatory ~ $ sudo apt-get install indi-full kstars-bleeding
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
indi-full : Depends: indi-nexstarevo but it is not installable
E: Unable to correct problems, you have held broken packages.


Any idea how to fix this?

Steps to adding a custom driver to my git copy - by: fm

Hi,
Steps to adding a custom driver to my git copy.
all in the title. I already have it compiled and tested, but I probably messed up with a bunch of files from the indi tree
to get things working...
So I'd like to make that cleanly from a brand new and unspoiled git tree.
The code comes in two parts, one for a (relatively small) dedicated library, and the code for the driver itself.
I'd like to add that to the tree so that the standard indi build procedure also takes care of my lib and driver.
Is there a guide describing the proper way to do that ?

Thank you in advance
best regards
