Hello Jaseem,

okay, thanks for the confirmation, so I know what to do, tilt the earth a bit ;-)

Now the object is a bit more away from the zenith and calibration worked. Guiding deviation 0.8".

Hello wvreeven,

thanks for the quick reply. I am pretty sure, it has nothing to do with the things you mentioned. I just tested again with an object near 30° height, calibration works like a charm. back to the zenith it fails.

I am using a stellar mate with the Indi_eqmod_telescope driver. The mount is connected via the PC-direct cable (lynx) to the raspberry.

Regards

Hello,

I always have guiding problems near the zenith. Yesterday I was observing M31 and it worked flawless with guiding variation around 1". Today I tried IC5067 (pelican nebula) which is right now close to the zenith and I canÄt even finish guiding calibration. I had that in the past and I wonder, if my mount is defect or if there are any settings to change.

I am using the EQ-6R with a very lightweight wide field set up currently.

any hints?

Regards

Amin

Ok, I am slowly getting closer. As the setting of 16 bit RAW is correct, I tested the coordinate origin setting in PixInsight for FITS files and set it back to Upper left corner, so now I don't get the grid anymore after debayering, but a very blueish color, even in my darks, what to me does not make sense for a RGGB matrix, I would have expected it to be greenish.

Thank you for that link, I know this site.

I still think there is something wrong either in the settings or in the Pixinsight import process.

Please see below a comparison of the RAW 16 bit after: debayering, linear fit of the color channels, ABE and Background Neutralization and Denoising using MultiScaleLinearTransformation. It has nearly no color and still so much gridding.

To the right is a RAW(!) I took of the same object just mirrored with the camera setting to RGB 24.

Thank you guys for confirming RAW 16 bit is right.

But how do I get rid of this grid in Pixinsight? Do I have to set something special for the fits-fileformat? I changed the coordinate origin already as I read somewhere this is the reason for blueish instead of greenish pictures after debayering (wrong starting point of the RGGB-patttern). But I still have this grid.

Thanks in advance

Hello Helge,

thanks for your reply. That is exactly what I am experiencing as well, a huge amp glow with USB 2 and no amp glow with USB3.

What confuses me right now though is what settings I should use with an ASI color camera in INDI. So far I was using RGB 24, but ZWO says I should rather use RAW 16 bit. When I open up these RAW 16 bit images in PixInsight I see a grid which I can't get rid off. (picture to the right). So I wonder if this is really the correct setting.

Regards

Amin

I am currently checking with ZWO, if the amp glow of my camera is a defect or not and they asked me for raw files from the camera.

I sent them the files I took so far with image setting set to RGB 24. They told me this setting is wrong and I should use RAW 16 bit.

And now my whole calibration workflow in PixInsight is screwed up, after calibration and debayering, I get RED images now with stronger amp-glow!

So I am trying to isolate the problem and want to start with checking the settings in Ekos: for the ASI 183 MC Pro (color camera) is it correct to use Raw 16 bit as a format and RGGB as debayering mask?

I am asking for the debayering mask as well as I see a blue tone when I debayer even my darks with this mask, so I am wondering, if this is the correct mask to use. Additionally, I don't know, if this settings has any effect on the transferred image rather than the metadata entry in the FiTS-header.

Any help appreciated!

Does nobody have the same issue? Can someone from the developers confirm this?

The setting of half step / full step is not stored properly. Even if set to half step and saved the driver is set to full step again when restarting.

This might not look like a big issue but it complicates atomization as you have to start the system manually and correct the setting prior to the imaging.

Thanks Eric,

focussing enhancements are highly appreciated. This is my weakest point in my setup right now. looking forward to my Moonlite clone.

Will it help the autofocus module to use a Bahtinov mask? I am thinking of getting one for manual focussing for the time being until my focus motor is ready.

Amin Sharaf replied to the topic 'Re:Horizon Data' in the forum. 2 months ago

I am using the same program and had a look at the export file. It is basically a list of lines with 2 values, one for the azimuth and the other for the altitude. I wanted to enter the values manually. For 0° it say 31.8 in the file, so I tried to enter 31 anyhow but failed.

Amin Sharaf replied to the topic 'Re:Horizon Data' in the forum. 2 months ago

Thank you Eric, I found it, but excuse my dumbness: how do I enter Altitude information. I have a series of data from Observer Pro with e.g. 31° (tall tree), I tried to enter 31, but it does not accept it.

I read in old posts from 2016 about a horizon module to take local horizon constraints like neighboring buildings into account.

I could not find it in the latest KStars version. Is this module still around? Would be very handy to incorporate this in the scheduler's calculation for the best targets.

Amin Sharaf created a new topic ' single complete frames in-between correct ones from my ASI290MC' in the forum. 2 months ago

Hi, I use an ASI 290 MC for guiding and recently it starts showing complete black frames in-between guiding. First I thought it was clouds in the sky, but that's not the case.

Sometimes it helps to switch binning to 2x2, it then displays stable frames, immediately when switching back to 1x1 the frames get completely black again.

I use sub framing with a 128 pix box. Does anyone else have this issue?

Cheers
