  1. I have searched SGL for a tutorial incase this has been covered so forgive me if it has. I've also searched the web in general and couldn't find a full tutorial to do this, so i have collated a couple of tutorials that make it work. I have managed to get SkySafari to work with a £32 ish Raspberry Pi3 and the cable that came with my scope with a usb to serial converter - the same things you need for connecting to a PC. It allows me to control the scope using the SkySafari Plus app on my tablet or phone AND it creates a wifi hotspot on the Raspberry Pi so it doesnt have to be on a network to work. This also turns the pi into a natty mini wireless router which is handy if you travel since it gives you a private wireless network when plugged into hotel wired internet ? ***STANDARD DISCLAIMER*** I AM NOT RESPONSIBLE FOR ANY DAMAGE THAT MAY OCCUR TO YOUR HARDWARE BY FOLLOWING THIS POST OR ANYTHING LINKED TO THIS POST It takes about 30 mins to do the tinkering, make sure you use the latest LITE version of raspbian. You need: Raspberry Pi 3 Portable power to it (preferably) Raspbian Lite Image file Appropriate cables to connect your Telescope to it via USB Computer connected to network Network cable to connect Raspberry Pi for initial setup A GoTo / Push To etc telescope mount compatible with SkySafari Plus / Pro A nice case for the Raspberry Pi You need to know a little about accessing the Raspberry Pi by SSH. For windows, use Win32 Disk Imager to burn the latest Raspbian LITE image to a micro sd card. Open the card on the pc (called boot) and make a blank file on it called 'ssh' - no file extension. This enables ssh access automatically. Stick it in your Pi and plug it into your network router and a power source. Find its ip address - i log into my router by typing its ip address into a web browser and look at connected devices, there are other methods though. I use a program called Putty to ssh. There are many tutorials on how to do the above and it isnt as hard as it first seems. I used 2 tutorials to do this and i will link to them directly as the original authors explain it better than me. The first one is muuuch longer than the second which is just 3 steps so bare with it. ***NOTE*** When the first tutorial suggests a reboot after the upgrade, DO IT! Then ssh back into the Pi and continue. Don't bother rebooting after tutorial 1 either. Tutorial 1 - Turn Raspberry Pi into a portable wifi hotspot See 'CONNECTING' after doing step 2 in the next tutorial to actually connect to the scope as what you have just done changes it a bit. Tutorial 2 - Make it talk to SkySafari App and the 'Scope You can now unplug the pi from your router. Plug your USB to serial adapter into the pi, your telescope cable into that and connect it to your scope as you would do with a pc (mine is into the AutoStar hand box) and use it as a stand alone adapter just like the £200 SkyFi adapter! CONNECTING: To connect SkySafari to the pi you simply connect your tablet or phone to the pi's network like you would any other wifi network, i called mine Scope, connect using the security key / password you made up in tutorial 1. Open SkySafari and follow step 3 in the second tutorial but with IP address 192.168.0.10 - the port is still 4000 (unless you changed it) If you are at home and your cable is long enough to reach your router you can plug the pi into that and use your home internet too - which you cant do with the SkyFi adapter! I am going to shorten my serial cable to make it a neater package, i can always solder new plus to make an extension if i ever need one. I am also working on finding out how to make it share usb internet so a 4g dongle can be plugged into it when out and about since when you connect to the pi's wifi in the field you will not have internet on the device connected to it. Also the Pi could possibly be used for imaging or tracking, someone on here will probably know more on this.
  2. Starting my 1st IOT project. Since i've been an astrophotographer with no permanent setup, it makes sense to reduce the physical footprint (and the weight) of as many equipment as possible, as well as to do better cable management. I am soon going to start using Astroberry Pi server, an Ubuntu based suite for Astrophotography. Just purchased a Raspberry Pi 3B along with a 3.5" display for that. Lets see how it goes.
  3. Hi all, I'm trying to connect SkyWatcher Synscan to my MacBook Air via wifi adapter using EQMac v2.0.0 beta3. According to the release note of EQMac v2.0.0 beta1, it supports wifi as well as serial connection. However, I couldn't find any document for wifi connection. What I'm trying to do is.. 1. Establish Wifi connection to "SynScan_WiFi_####" 2. Configure following connection in EQMac's Preference Connection Type: TCP/IP IP Address: 192.168.4.1 Port: 11880 3. Close Preference setting However, EQMac console is still gray out.. Appreciate if anyone share how to configure EQMac for wifi or alternative application/tool to connect Synscan to Mac via wifi.

Powertank was bought at christmas and has only been charged once The star diagonal got dropped and the silver insert (the bit that you put the eyepiece into) that screws into it became slightly loose in the threads so I repaired it by putting superglue on the threads and screwing it back in. It is held solid now and no glue is visible and all the eyepieces fit perfectly. All instruction manuals and tools still in bag. Non Smoking Household £400 ono reduced Location Bolton, North West England. Collection or I can do local delivery in person. I would prefer this as postage would be expensive also the risk of damage in transit. If needed then I estimate around £15 due to size and amount of items if sent by courier.
  5. Hi guys, I been googling a lot and was not able to find a solution how to connect EQMOD to the Mount via SW Wifi Dongle... it looks like EQMOD needs COM Port to be used.... I do remember there was some kind of "Virtual Com port bridge to Wifi"app back in Win98 days... But I cannot find anything similar for Win10. I want to test EQMOD auto-guiding via WIFI, - I know, it's not reliable, but I want to try as I have Skywatcher wifi dongle and my USB to Serial (RS-232) Converter Cable is wayyyy too short to keep my PC (and me) in warm. I am able to connect with SynScanPro app to Wifi Dongle and even sync it with Stellarium nicely... Only Auto-guiding missing... Any ideas?
  6. Hail esteemed astropeeps I set up the Celestron wifi module on my Nexstar 6SE (good wifi signal, no problems connecting), opened Skysafari 4 onth' IPad, but all I got after I had been into skysafari settings and put in the IP address was connection failed. I have the settings on direct input (it is like that on the actual wifi module too) alt-az go to, selected my telescope, but always connection failed. Tried it on sky portal on IPhone 6, and whilst it did connect and slew the telescope, the alignment procedure failed every time. Does anyone one have any advice, please? Why won't Skysafari 4 connect (actually 4.5.3) and why won't sky portal align? I've checked other forums and other posts and all the settings seem to be correct. What button have I failed to check? If you have screen shots of any settings, that would be helpful.
  7. Hi, I continue to get my Star Adventure to perform better. One very big problem if you have a camera that you can not tilt the display at, no tiltable display. I have the Canon 6D. It's almost impossible to see the display and do settings when the camera aim upwards to the zenith. I have until now used a very tall tripod, but that is something very big and not so friendly when travel. Instead of buying a new camera I now test to use an app in my smart phone and used that to see the display in live view from the camera. I have written a tutorial in an early stage of how I do that: http://www.astrofriend.eu/astronomy/tutorials/tutorial-canon-remote-control/page01-tutorial-canon-remote-control.html I will correct and add more information when I get more experience from this. I'm sure most of you alreday have done this, my concern is, how hot will the camera be. I have bad experience from this from earlier test with live view. /Lars

    The Crux

    Got tired of the mess of cables and loose devices I had to always put together and dismantle after each astrophotography session so I figured I'd do something about it. This tray will sit nicely under the tripod and provide a hub for everything including Fused Power, Raspberry Pi, USB Hub, GPS, Dew Heaters, Long Range WiFi etc... First version will be really crude as I need to have this working in less than a week as I'm going on a holiday taking my astro gear with me.

  10. Hi there, in an effort to simplify the setup procedure of my field observatory I spent a couple of hours yesterday researching solutions for a Power and Comms distribution box. I eventually settled on a very simple solution based around a cheap IP54 rated outdoor enclosure sourced from a local DIY store (UK readers will recognise the name B&Q). My power in the field is supplied by two 10ah Tracer LiPo batteries, which have served me well now for the past two years. In addition to the batteries the solution needed to accommodate a dinky little TPLink router, which provides me with WIFI control of my SXW mount via SkySafari from my iPhone. I'm pretty pleased with the net result. Had some concerns initially that the proximity of the batteries to the router in the enclosure might cause some interference with the comms, but completely unfounded, it all works like a charm.

  11. Hi there everyone, I’m interested in getting peoples take on where they think mount control technology will go in the years to come. I currently control my Sphinx SXW remotely and almost entirely from SS on my iOS devices. Although this works a treat, it still employs a technique that is a mish-mash of separate components rather than an integrated wireless solution, along the lines for example of TV wireless integration. As far as I am aware none of the major players in the amateur astro mount market have yet addressed this in the form of a complete integrated solution, I may however be wrong? Using current technology, I can see a future product whereby the mount hardware arrives via conventional delivery, you receive as part of the package a code for pre-paid access to an app from an online App Store, which you can then download and install on your remote control device, be this Apple or Android. You then power up the mount which will hook into an available wireless network. At this point the mount just sits and waits for connectivity from the control application. You start up the control app, connect to the mount then have complete control of the mount from the remote app. All contributions appreciated, let’s innovate?? Paul.
  12. Celestron Sky Q module. Purchased new back in 2015 to use with a CGEM (which is also up for sale). The device creates a WiFi signal which you can connect to with an iOS or Android device so that you can control the mount with Apps such as Sky Safari (that is what we used). Alternatively you can use Celestron’s free Sky Portal App. £70 including delivery. The item is also up for sale on UK ABS
