I attach the steps to make the image of iAstroHub 2.2 with the working AP mode in CX919.  See the previous post for the image file and details. 

Hi Anat,

 

thanks for all the good work!

I've ordered the CX919 from your link, am still waiting for it to arrive. One thing is not clear to me; do i need to use the image file "iAstroHub2.2_CX919_20150311.img", write to SD, insert & run and that's it?

Or do i need to use iAstroHub2.2 src.zip from Sourceforge and follow steps as described in file "steps CX919.txt"?

 

Kind regards

 

Jasper

Jasper,

 

You can just flash the image file "iAstroHub2.2_CX919_20150311.img" Nothing else to be done. The step is for people who want to build everything from sources.

Hi anat,

Could you please give a detailed camera list of which are supported in ver 2.2?

I use the latest version of gphoto2 and pktriggercord. Please refer to the following websites for supported cameras

Thanks Anat,

But I also want to know the list of QHY and SBIG CCD cameras

I see.  For SBIG cameras, iAstroHub should work with all recent cameras with USB ports. It has been tested with ST10, ST2000, STF8300. 

For QHY supports, please refer to the website on openskyimager:

Anat,

Perhaps a noob question, but this is baffling me.  Pointed West, auto guiding is fine.  Pointed East, guiding works for a few seconds and then is rapidly lost only in one axis.

I aligned on a different star, and the same issue.  I rotated the camera (QHY5II-L-M), recalibrated, and the same result.  This happened over two separate nights, only when pointing East.

 

Thoughts?

Jeff

Set Dec gain to zero and see the result. If it happens, it means the problem with your mount setup

Hi everyone

I'm new to this forum and also new to iAstrohub and I'm confused.

I have a CX919, an SD card with iAstroHub2.0_CX919_20150106.img, and no idea what to do next because instruction mention MK808.

 

Therefore just need to know if I should follow these steps:

        "3) Now you need to make the MK808 boot Linux in the micro SD card directly instead of Android. This process is called "Flashing Kernel".

      3.1) Download the Linux kernel image from: https://drive.google...dit?usp=sharing

      3.2) Download RKAndroidTools v1.35 and the Finless ROM from: http://www.freaktab....-1-6-Custom-ROM    3.3) Unzip the Finless ROM and follow the instruction to install the device driver.

      3.4) Run RKandroidTools

           3.4.1) Erase IDB

           3.4.2) Leave all checks as default but replace the recovery image with the new "Kernel_iAstroHub_MK808.img" by clicking the rightmost column.   3.4.3) Flash ROM", etc?

 

Any help most appreciated. Thanks

 

Get the latest image file

http://www.cloudynig...true/?p=6490170

You just uncompress and write the image file to your uSD card.  No need to flash the kernel. 

 

Skip Step#3

Hi Anat

Thanks for the help ... works like a charm! Just have to figure out how to use it.

Great project especially for remote field work.

Thanks again

Phil

Hi Anat

 

I installed your software on my RPi2 this week and would like to thank you. It's amazing.

I use a Canon T2i (550D) as my main camera, and I have the Magic Lantern on it. One of the functions I like in ML is the silent shot. I use it to avoid vibration due to mirror flip. As a suggestion, I modified your shooting script (shutter2.sh) and added the "live view" command to the script. It acts like a delayed flip mirror and make things work perfectly. The only thing I could not correct yet is that the shot time counter became incorrect. It do not consider the delay and the counting finishes before the camera.

 

This is the command line I modified:

sudo gphoto2 --set-config viewfinder=1 --wait-event=5s --set-config eosremoterelease=Immediate --wait-event=${Exp}s.......

 

I wish you could help me to correct the shot time counter when you can...

Hi Anat,

What is the lin_guider version now in iAstroHub?

I see the 3.0.0 version is released with more astrocams supported.

Daniel, 

 

Nice to see you modified the code. You may need to observe the delay for various exposure times and add/subtract the value from $(EXP) if the delay is consistent. 

 

Best regards,

Anat

I use LG2.11 on iAstroHub2.0. If you want to use LG3.1, you may need to DIY for now. You can find the diff between my code and the original code. Then apply the diff to LG3.1.
