Interesting, I had looked at thee when they came out, but of course they were sold out, now that availability is improving I might have to pick one up.

Are you using a wireless wi-fi adapter to do ad-hoc networking so you can simulate a sky-fi, or is your system hooked up to a hub/router?

Mike,

Yes. I use the Orion Starshoot Autoguider (aka QHY5) for the development.

I tried a wifi dongle (Asus N10) and found that it was pretty slow for an adhoc network. I use an Edimax Nano router instead.

This is the interface of PiAstroHub. A user can control Linguider and DSLR from a webbrower in a mobile device.

There is a feature to find a guide star automatically in the new version of Linguider. The feature is incorporated in PiAstroHub. A user can also manually select a guide star by clicking "Tool" in "Guide Star Selection". That will open another window to manually select a guide star.

I have now installed the PiAstroHub on my Raspberry Pi. It's using Nginx and php5-fpm for the webserver.
My QHY5 should arrive today or Saturday.... will report on how it performs late on.

To use PiAstroHub as SkyFi to connect between SkySafari and a mount, follow these steps:

-------------------------------------------------
sudo apt-get install ser2net
sudo sed -i '$ a\5555:raw:0:/dev/ttyUSB0:9600 NONE 1STOPBIT 8DATABITS' /etc/ser2net.conf
sudo /etc/init.d/ser2net restart
-------------------------------------------------

It is that simple Now all tcp communications via Port 5555 will be redirected to a serial port. I recommend using a PL2303-based usb-serial adapter.

Then set Port as 5555 in SkySafari. Done! PiAstroHub will function like SkyFi.




Hi there,

First post here, but been reading loads! Thanks for a great post on integrating the Pi with a scope!

I have a Skywatcher 130p AZ Goto with the latest synscan firmware. I am quite IT literate (I'm an IT consultant!), so I do understand all wonderful the things you are doing. I am mainly a Windows consultant, but do come across Linux and use it daily so I am quite comfortable at the command line. I have tried the above on my Pi, but Sky Safari will connect briefly, then ALL tcp communications stop until I reboot the Pi!

I have tried changing a few things inthe ser2net.conf file such as prefixing it with 192.168.0.114,5555 that should only use my WiFi adapter and keep the LAN connected. One thing though, I do have the WiFi connected to my LAN and not in an adhoc network...is this the issue?

Would love to hear from someone, as it's been driving me mad all weekend !!!

Clear Skies!

Tel

Hi Tel,

I didn't have the issue. I mainly use Ethernet connection. I also tried Wifi connection using an Asus N10 USB adapter once without any problem but it was a bit slow.

Is your Wifi adapter connected to a powered hub? It is recommended to use a powered hub because the power from Pi is not sufficient.

I finally got Pi to work with both QHY5 and QHY8L

Nice work Anat.

I have the 256MB version of the RaspberryPi. Are you using the 256 or 512MB version?

Also, are you overclocking the processor any?

This is going to be my next project.

Thanks,
Brent

Hi Brent,

I am using the 256MB version. It is sufficient for controlling both QHY5 and QHY8L. I overclocked it to 900MHz

Hi Everybody...

My name is Klaus and I am new to this forum, but familiar to many kinds of guiders and also a bit to Linux.
I have bought a RaspberryPi (Rev. B) and installed the actual 2012-10-28-wheezy-raspbian.img. Then I followed the instructions from Anat's post from 08/26/12 to install Lin_Guider and the QHY5 driver.

Everything went well with no errors at all. When I connect the QHY5, I can see, that it is recognized by the OS (looking at /var/log/messages). I started Lin_Guider and configured it to "QHY5".

But now - whatever I do - the QHY5 is not recognized by Lin_Guider. "Cannot open device QHY5"...

Any idea for me?


And beyond that - a few questions about the project:

Is there a chance or are there any plans to enable binning on the QHY5?

And what about dithering - has anybody thought about that?

I am really exited waiting for your answers;-)

Best regards
Klaus

Got it...

I also installed indi & PHD - after that, Lin_Guider worked!

Best regards

Hi Klaus,

I think that the camera firmware is not properly loaded. You don't need to have INDI and PHD. Download the firmware from
http://sourceforge.net/projects/cccd/files/firmware/

And use the command
sudo dpkg -i firmware-ccd_1.0_all.deb

use lsusb to see if the camera is recognized.

Great work Anat!!

Since the Rasberry Pi seems to have a MIPI CSI-2 camera connector, do you think it would be possible to connect a daughter board with a CCD fitted on it one day?

I'm just thinking of new ways to play with this cute piece of hardware...

I think the CSI-2 interface may work only for webcams.

Anat great work, would this work using the odroid boards.
http://www.hardkernel.com/renewal_2011/main.php
Also what application are you using to capture from and control the qhy8l? Could this work with other dedicated ccd imagers.

I think this would work with odroid. I am now using MK808 (Dual core Rockchip). It is small and fast. I am using a modified CCD program
http://sourceforge.net/projects/cccd/
to control QHY8L

Congratulations for this project! I'm truly interested on it!

Have you done any field tests? I'm mainly interested on autoguiding. Shutting my DSLR is just a secondary objective.

Just to clarify, I think almost prepared to run it: I have a QHY5 with a guider scope, a Raspberry PI with a USB WIFI dongle, a GC5-GT mount, experience with linux...

Hi GonZoo,

It is not tested in the field yet. Please send me your email address. I can send you the code for beta-testing.
