HI,

I'm having an issue when tying to use FITS image format. Hoping someone could help. The imaging camera I'm currently using is a modified Canon 450D DSLR along with the the Canon DSLR Indi driver. To date I've been taking NATIVE images in the Capture module because whenever I try to use FITS format the images always show corruption at the top of the image. Native images show no such problem. I can see benefits for me to move over to FITS images so it would be nice to identify whats going on here. Has anybody else experienced this and can possible shed some light or maybe Jaseem can offer some advice. I have attached a screenshot of a FITS image that demonstrates what I'm experiencing on all FITS images.

Thanks.

Hi Jasem,

I've tested the nightly build of Kstars 3.3.3 dated 23rd July but the issue is still there. I suspect you may have changed the wrong occurrence of code as the lines I changed are still there unchanged in capture.cpp at lines 5194 and 5197

// Wait until cap is unparked <<<<<<<< line 5194 changed by me from // Wait until cap is parked
if (calibrationStage == CAL_DUSTCAP_UNPARKING)
{
if (dustCap->isUnParked() == false) <<<<<<<< line 5197 changed by me from if (dustCap->isParked() == true)
return IPS_BUSY;
else
{
calibrationStage = CAL_DUSTCAP_UNPARKED;
appendLogText(i18n("Dust cap unparked."));
}
}

This is the output from Kstars. See the times from uparking Dust Cap to Dust Cap unparked - one second.

It actually takes 20 second as you can see from The FlipFlat output.

Thanks Jasem,
I'm running the latest viersion 3.3.2 on edu.kde.org/kstars/#download . Guess I just need to wait until v3.3.3 is available.

Much appreciated.

Ray.

Hi Jasem,

This is a paste from a previous comment I posted a while ago . Just wondering if this bug will be corrected at some point? I can correct the issue under Linux by making the changes to the source mentioned but I prefer to use Kstars under Windows and I don't have the build environment to recompile under windows.


When taking a Light frame from a starting position of Shutter closed all works as expected.
When taking a Flat frame (external light source) from a starting position of Shutter closed
Kstars/ekos commands the shutter to open correctly but doesn't wait for the Shutter to open, it
immediately takes the frame while the shutter is still opening. I was able to get this working
correctly by making the follow change to capture.cpp in Kstars. Hope this is useful to you.

Change from...
// Wait until cap is parked
if (calibrationStage == CAL_DUSTCAP_UNPARKING)
{
if (dustCap->isParked() == true)
return IPS_BUSY;
else
{
calibrationStage = CAL_DUSTCAP_UNPARKED;
appendLogText(i18n("Dust cap unparked."));
}
}


..to...

// Wait until cap is unparked <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
if (calibrationStage == CAL_DUSTCAP_UNPARKING)
{
if (dustCap->isUnParked() == false) <<<<<<<<<<<<<<<<<<<<<<<
return IPS_BUSY;
else
{
calibrationStage = CAL_DUSTCAP_UNPARKED;
appendLogText(i18n("Dust cap unparked."));
}
}


Tanks.

Hi Jasem,

An update on this.

I have been able to get my DSLR working with FlipFlat by adding 'CCD_HAS_SHUTTER' to the 'SetCCDCapability' function of gphoto.cpp.

I have also detected another issue that affects both the CCD Simulator as well as other CCD's.

Thanks Jasem,
Could you also clarify for me too. In Calibration it is only possible to select 'Dust Cover with External Flat Light' OR 'Wall' location. When using the Wall option it only moves the mount but doesn't control the Flap or Light as the External Flap Light option does. Could it be possible to select BOTH these option not just one? I can work around it by taking a dummy flat frame with Wall option selected to move the mount then follow with the real Flats with the External Flap Light selected but it would be nice to do it in one step.

I'm relatively new to ekos/indi but loving it.

Hi all,

I am trying to use FlipFlat driver with a Canon dslr but i'm having problems. Everything works OK when using the CCD simulator with FlipFlat as you can see from this log extract...

Should FlipFlat work with a dslr ? Is there some configuration setting I'm missing?

Any help appreciated.

I guess noone else has experienced this. I'm wondering if my small focal length could be the issue. On the Polemaster setup a 25mm focal length is used. For Sharpcam a focal length of around 120mm is recommended. For ekos greater than 1 degree FOV is recommended as per the youtube video. My 25mm focal length gives me a FOV of around 10 degrees. Is there an upper FOV limit when using ekos Polar alignment?

Hi, I'm new to ekos/indi and first post here. I've spent the last two evenings trying to set polar alignment on mt eq6-r pro using the polar alignment method in ekos. While the procedure works sucessfully as per the youtube video I cant achieve any level of accuracy or consistancy of results. For example my initial attemp showed my polar alignment to be out by 56'. I adjusted for this and retested. Retest showed PA to be out by 9'. I readjusted and retested. subsiquent tests/adjustments gave ever worsening degrees of error. Last night I setupPA using Polemaster and quickly got to a point where Polemaster said PA was 'spot on' and subsiquent retests using Polemaster confirmed this result. At this point I measured the Polemaster derived alignment using ekos several times without making any changes or adjustments to the mount and results fluctuated from 4' to over 10' of error. I'm running Astrometry local but also confirmed results using online solver. My setup for both ekos and Polemaster are the same using a qhy5l-ii camera with 25mm FL lens mounted on the RA axis and also tried with similar results using canon dslr 450d. Assuming Polemaster is giving the correct alignment can anybody suggest what I may be doing wrong to be getting inaccurate and fluctuating results using ekos.
