  1. Hi does anyone use 'Skywire' via Skysafari to control a Celestron Evolution with the starsence accessory fitted? My queries are these: What is the maximum cable length that can be used and are there any suppliers? and does Skysafari recognise the starsence accessory for initial Goto alignment ? Thanks people Bill (Williamnohair)
  2. Hello, I am trying to control my Heq5 pro via SynScan (ver 3.10) with Stellarium (on MS Win10, 64 bit). I got the proper cable and adapter to connect to the usb port (via an adaptor for the RS-232). In Stellarium I follow the instructions to add a telescope / configure / add new telescope but when I get at the level of the device settings (see image), the field to select the port is blank and cannot be edited. I know I am using port : Port_#0001.Hub_#0004 (from checking the device manager) on my laptop. I tried installing Ascom but I still can't find the port there neither. I tried using a different port #3 but same issue. Anyone knows a work around the issue? Thank you \\
  3. 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.
  4. Hey Everyone, I bought a new laptop two days ago. Even though I do have the standard software like APT, PHD1,2, CdC, Stellarium, DSS, ASCOM, EQMOD etc. etc, Anyone have any other software in mind I could install? I'll admit that I kind of hoard them on the PC and not really use them.
  5. I visited the International Astronomy Show in Warwick the other week. Just inside the door there was a young chap selling dew control products. The gear was lightweight and relatively inexpensive, so I thought I'd give it a try. I picked up one heater band (for my Esprit 120) and one 4 channel controller. The controllers he had at the show all had a 2m power cable. I said I would have preferred another metre. Tim (the young chap) said it was not a problem. He would make one with a 3m cable and send it out to me. He obviously posted it first thing Monday morning because it arrived on the Tuesday. What I liked about the unit was how lightweight it was. It also had a belt-loop sort of thing attached to the back. This allowed the elasticated part of the heater tape to pass through, so that the controller could be fixed to the scope itself. Here is how I have done mine: The controller works off one button (the small red button just under the printed text 'Quad Channel Dew Controller' on the case). When you power up, Output 1 is illuminated. Press and release (less than 1 second) to cycle between 0, 20, 40, 60, 80 and 100 percent output. There are 4 lights: 0% power = no lights, then each light comes on singly for 20, 40, 60 and 80 percent. All four lights are illuminated at 100% power. To switch channels, hold the button down for a bit longer (more than a second) and release. It is remarkably simple to use. With my other dew controller there seems to be a bit of 'uncertainty' as to whether or not the phono plug is properly seated. With the Dewcontrol unit the seating is extremely positive. One possible downside (or upside depending on your point of view) is that, when you power down, the unit does not 'remember' your settings. You start from zero power in each channel at each power up. This has caught me out once, unfortunately, but I will soon get used to the new way of doing things. I am very pleased with the unit. It is lightweight, inexpensive and works well. It is good to have a range of alternatives and this one is from a UK manufacturer. The heater tape worked just fine too. It was made by the lady who co-worked the stall with Tim (her name was Barbara). It seemed to be high quality. It is hand sewn. It worked straight away (unlike a top-end brand I bought a couple of years back that I had to pick apart and fiddle with). I am not sure if these are the same tapes that Tim sells on his website. My wife recalls that the brand of heater tape was W&W Astro - and Barbara's website is here http://www.dewheater.com/. I have no connection with Tim whatsoever. When looking up some info (his name for example) for this review, I found that his website was a little difficult to locate - if you are interested it is http://www.dewcontrol.com/. I may get one of his two channel units for my more portable setup. Steve M
  6. Maybe you have plans to build an astroserver to control your equipment. One thing to figure out is how fast computer do you need. Too fast and it take more power then necesary (my computer is battery operated), to slow and it will not work properly. I have made a table over the CPU loads on my Astroserver during different work: http://www.astrofriend.eu/astronomy/tutorials/tutorial-cpu-load/tutorial-cpu-load.html Maybe it could be to some help for you. /Lars
  7. Hi guys This topic was opened to see if anyone can help me determine which operating system is compatible with the telescope control. I have a Skywatcher 130/650 I can not control my GoTo telescope and windows 7 but I can not see the planetarium program.
  8. Hi guys, Tonight i am piggy backing my DSLR/Lens combo on top of the frac for the first time, i've just been out and balanced everything. I can see that the biggest problem i am going to have is lack of control over the 2nd DSLR. Usually i use APT via remote desktop to control my DSLR from in my living room. But as far as i know APT doesnt offer dual camera control. I've done a few searches and nothing at all is popping up about a way to do this and i should add that i only have the one imaging laptop so cant use a separate laptop for control. Anybody have any experience with this?
