pauledd replied to the topic 'Image Autoguiding' in the forum. 3 days ago

What I do not understand is that 15 seconds exposure mentioned in the video. If I remember correctly he said he broke the exposures into 15s subexposures and sum them in ram for the final exposure for
the image autoguiding with the main camera. Then another person in the video asked for that 15 seconds because astroimaging would normaly use exposures 1 to 15 minutes and he said you could also use the guiding scope to do the image autoguiding and use the main camera for longer exposures. That was the point where I was wondering because at the beginning of his presentation he claimed the errors that are introduced by those other methods to guide (fov, differential flexure,jitter) and then he recommends one of those to have longer exposures on the main camera. Maybe I missunderstood something :oops:

Thank you, I'll do that when I finish the hardware part and everything works manually.

I am not shure about the FlipFlap but when you say "command set" you mean I need to built some kind of USB controller to drive my dustcover with the FlipFlat driver?
:whistle: thats far beyond my skills, then I will stick to the ServoBlaster and wiringpi like in the article.

pauledd created a new topic ' DIY Flatfield Dustcover with RPi' in the forum. 4 days ago

Hi there

Since I discovered a regional dealer that got flatfield foils with a evenly white spectrum
I plan to build a DIY flatfield dustcover in the next 2 to x months.
My plan is to follow the nice article
indilib.org/support/tutorials/165-diy-au...telescope-cover.html
but since I never had anything to do with servo motors its a bit unclear to me
what kind of servo I should look for. Especially what force and what gear (metal or plastic).
And of cause it should be as cheap as possible.

I currently focus on the BMS-390 DMH servo that has metal gear and a force of 46NM/cm/4.8V.
That mean that it should handle about 4,6 kilogram 1cm away from the axis. 10cm away makes
460 gramms. My flatfieldfoil will be taped on an 22x22x0,1cm aluminium plate that weights about 200g.

The flatfield would be switched on/off by a relay.
Now my qestion is would it be possible to integrate the flatfield into indi, is there already an solution in indi or do I need to write a new driver
for that.

pauledd replied to the topic 'Stepper focusser directly from Raspberry' in the forum. 1 week ago

I maybe solved it by myself by changing a few lines in rpi_focus.cpp:

I commented out two lines here:

...
bool FocusRpi::initProperties()
{
    INDI::Focuser::initProperties();

    //IUFillText(&PortT[0], "PORT", "Port","RPi GPIO");
    //IUFillTextVector(&PortTP,PortT,1,getDeviceName(),"DEVICE_PORT","Ports",OPTIONS_TAB,IP_RO,0,IPS_OK);

    IUFillNumber(&FocusAbsPosN[0],"FOCUS_ABSOLUTE_POSITION","Ticks","%0.0f",0,MAX_STEPS,(int)MAX_STEPS/100,0);
...

and I changed this:
...
bool FocusRpi::saveConfigItems(FILE *fp)
{
      IUSaveConfigText(fp, &PortTP);
 ...
to this:
...
bool FocusRpi::saveConfigItems(FILE *fp)
{
    //IUSaveConfigText(fp, &PortTP);
    INDI::Focuser::saveConfigItems(fp);
...

and to remove the deprecated warnung of auto_ptr I changed this:
...
std::auto_ptr<FocusRpi> focusRpi(0);
...
to this:
std::unique_ptr<FocusRpi> focusRpi(new FocusRpi());

and finally I have absolutly no clue if this was the right way to do it but my changes seems to work so far with the focuser.

Dear Kaczorek,
Today I tried to compile your astroberry driver again but I get errors from make regarding 'PortT' / 'PortTP' was not declared...:

Do you have any ideas whats wrong now? Maybe indilib has changed something recently or is my compiler to new?
