Hi,
There's any way that FITS Viewer can shows the HFR in all stars at the end of the exposures, just like it shows when it's focusing ?
Thanks

I made a similar project with this one:
elpanelandtape.co.uk/product/13-x-13cm/

Keep in mind that it's very dificult to use the same exposure for all the filters and adjust only the pannel brightnes.
I have an Atik 383 with a shooter that needs at least 2s of exposure to hide the shadow of the shooter, so i use about 2 seconds expusure with the brightness set to 90 (in a range 0-255) for Luminance, but for HA filter, with the brightness set to maximum, i have to rise the exposure. This will hapen with a DIY Flat Pannel or with a comercial one. It will be the same.

Yes the Arduino board will manage the brightness of the EL Pannel using PWM. The board will receive the value from Ekos (or another client).

A word of advice. It's very difficult to mantain a very low value of brightness of the EL Pannel without flickering (mine starts to flickering at below of a value of 50-60). There are diferent ways to connect the EL Pannel to arduino, some more elaborated then others, but you can start with something as simple as a Mosfet.
So, if you will do flats with a C11 and a CMOS, i have no doubt that you have to use very low values of brightness, or using something to lower the brightness without dimmering the EL Pannel (some sheets of paper, for example).

The Arduino IDE it's just like a text editor, you just have to open the ino (the firmeware file), make a change in the code if needed, choose your board, the port where it's connected and press a button. It's really that simple.

If you read the code you will find that if just want to use the brightness control, you have to replace just the line 79 line of the code...

You will need the dimmer if you want to set the brightness manually. If you want to adjust only using Ekos, you don't need it.

These kind of DIY projects, even a small one like the one you need, will always involve some adaptions / cuts / solder. But it's where the fun is :)

Exactly

There's actually two versions of the same arduino ino (one for Revision 3 and another for Revision 4).

I believe that both will work with Alnitak INDI driver, but just in case, get both :)

You can always use an EL Panel with an Arduino, load this firmware to arduino, and use the Alnitak driver

Nuno Gameiro created a new topic ' EQMOD Slew issue' in the forum. 8 months ago

Hi,

I'm trying once again to migrate from Windows 10/NINA/ASCOM to Kubuntu LTS/Ekos/INDI, in a permanent and remote observatory, but I'm facing a strange problem.

I'm using the latest stable version of Kstars with an EQ6 mount. Connecting to eqmod was successful, the polar alignment tool was a pleasure to use and setting a new park position worked fine too.

The problem it's that every time I try to slew the mount to West (ex.: from parked position or from East), the mount does not flip.  When pointing east the counterweights are facing down as they should but when the mount is slewing to  West the weights keep going up, causing the setup to almost hit the pier.

I've never had any problems like this with ASCOM.

There's anyone facing the same issue?

Hi,

I'm using EQMOD Simulator and / or Telescope simulator provided by INDI, not a "real" mount.

Thank you

Nuno Gameiro created a new topic ' Auto meridian flip issue' in the forum. 4 years ago

Hi,

I'm trying the INDI / Kstars / Ekos in simulation mode before doing a full install on the observatory PC.
I'm using the CCD simulator and EQMOD (in simulation mode).
So far, the only problem I have is the automatic meridian flip. The Log shows that the auto-meridian flip is started, the sequence is interrupted, but the mount doesn't slew.

After a while, the log shows:
"The meridian flip of the telescope has timed out. Please make sure your mount supports the Meridian Flip."

And then:
"Retrying meridian flip again ..."
But nothing happens.

I've also tried the Telescope simulator, but it's the same.

I know from other users that the problem happens with other "real" mounts, which indicates that the problem is not by using the simulator.

Any idea ?
Thank you

Hello

Just to say that i successfully finished the driver :)

Thank you very much for your help :)

Ok, thank you a lot.

As i said in the begining, i'm ASCOM formatted. B)

The command of my filter wheel it's very simple. "M23" to move from filter 2 to 3. But even setting Ekos to load configuration file on connection, the comand sent when i connect it's M02 (2 it's the filter saved on FILTER_SLOT property) .
CurrentFilter it's 0, i believe.

I'm almost there :)

Thank you very much, that's works :)
One last question, and one thought...

When the client (Ekos) connects the wheel, the slot number it's defined by currentFilter or it takes the slot number on the config file ? If it's the first option how can i get the slot number in config file (currentFilter = <get_slot_number> ) ? If it's the second option, i'm doing something wrong :dry:

A thought...
What's the reason for the client don't save the slot number when the filter change ? If it's the case, everytime I stop and start INDI, the slot number in the config file never correspond to the efective slot number in the wheel. Am i wrong ?

Thank you once more
Nuno Gameiro
