I installed Open-PHD-guiding on the Pi with an assistance from a friend: http://stargazerslounge.com/topic/158463-open-phd-indi-server-qhy5-on-a-raspberry-pi/ Now I can run PHD guiding on the device from iPad or Android via a X windows program (iSSH for iPad). I am now writing a web application to control a DSLR camera and to view photos taken by the camera via a web browser on the device. And yes, Goto can be commanded from SkySafari I will keep you updated Anat Edited by anat (08/15/12 10:56 AM) Post Extras:       gonzothegreat journeyman Reged: 11/20/11 Re: PiAstroHub: RaspberryPi for Autoguiding+DSLR+GOTO [Re: anat]       #5370175 - 08/15/12 01:49 PM Edit   Reply   Quote Quick Reply   Greetings, I'm the 'friend' I'm also behind the following joined project with somebody else: http://code.google.com/p/eq-polar-alignment/ Still have to order my QHy5....

First we had the rush of people planning to buy a Pi to use as a regular computer with little IT knowledge, and I was a bit concerned about how it would work out, but now I'm starting to see lots of really cool projects like this Is it fast enough to handle the guiding software? I know the CPU in it is particularly weak (attempts to run linux with a GUI without GPU acceleration have been very painful!), but it's enough to handle a lot of stuff. And the GPU looks reasonably good, and could definitely take a lot of the load in a guiding app. Post Extras:       anat sage Reged: 06/03/04 Re: PiAstroHub: RaspberryPi for Autoguiding+DSLR+GOTO [Re: psonice]       #5370677 - 08/15/12 08:46 PM Edit   Reply   Quote Quick Reply   I am using a low-quality Class4 SD card to run Raspbian and it takes about 8 sec for a 2sec shot to complete a cycle.

I've finally got my Pi up and running in wifi master (AP) mode and have ser2net configured. I can't believe it was that easy -- to think I nearly bought a SkyFi for more than twice the price of the Pi! This will be great for me as I'm usually stuck up on my apartment roof with a netbook. I'm slap bang in the middle of Shanghai and due to poor visibility and blocked view in various directions, I can't always align properly, and used to rely on "syncing" a lot using KStars / INDI, which was painfully slow and cumbersome on a netbook. I've also been using gphoto2 for a while to control my DSLR, so I'll be doing that too. I'm interested in the astrometry.net solver too, I wonder how that will work in my orange skies. For autoguiding, I've added a piggyback mount to my ETX-125 and have a modified webcam, but have never been able to get a decent polar alignment, and the ETX mount isn't great anyway. With all the functionality sitting on the Pi however, it's one less item of faffing around to get set up, so I'm much more likely to try it now and succeed I think. I wonder how a focuser would integrate into this setup -- I remember LibINDI allowed for controlling focusers. An ideal setup would be taking a few photos with gphoto2, and doing rinse-repeat trial & error autofocusing. I plan to integrate my Pi in a project box with 12V / 5V PSU so I basically have everything contained in one box with one power plug. The dream setup would be an automated setup as the Autostar is so slow and archaic -- auto align, auto focus, Goto provided by Skysafari.

"Semi-auto" focusing is possible. The focuser movement and camera exposure are done in a series. Then the star images are compared by a user. The focuser is commanded to move to the position of the sharpest star image.

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!

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 assuming for this project, you are fork-lifting the whole thing to make it Linux for easier to support?? BTW, if it ends up to be not the optimal solution, one can always change it back to XBMC video player . On that front, will RaspberryPi or MK808 be a better dual-use solution?

It works very fine. But the 2 usb ports are occupied one by the usb wifi dongle the other by the Raspberry which handle the mount. To answer a question I have seen somewhere: the handle is needed to make it works. So there is no other room to connect a cam. The amount of the installation to drive an Orion Atlas mount is as follow: raspberry B 42€ box for rpi 10€ wifi dongle 10€ usb/RS232 14€ for a total of 76€ (100$) which is the half price of the skyfi orion device (in Europe). Unfortunately I have read somewhere that the usb inteface is unique and the 2 plugs share the same interface. So there is nothing to wait in term of performance. But maybe it is sufficient for autoguiding. Anat you are true, the MK808 looks to be a better alternative, wifi, bluetooth are included in device. But unfortunately there is only one usb plug. It would have been fun to make acquisition with the same device as the one that autoguide and drive the mount. But it seems not to be done even with the MK808.

I got several MK808 sticks from http://www.geekbuying.com/item/MK808-Dual-Core-Android-4-1-Jelly-Bean-TV-BOX-... It is the right one.

Both Raspberry Pi and MK808 works with a powered usb hub. In my setup I use: QHY6 for autoguiding QHY8L or DSLR for image capturing USB-serial adapter for mount control USB sound adapter connected to a hub without any problem.

Thank all testers and developers for your support. https://sourceforge.net/projects/iastrohub/ Now a tablet can control the autoguider, CCD, DSLR, and mount via a tiny hub I recommend MK808 (original with RK901 Wifi chip).
