  1. Sooo...I'm getting quote frustrated here. This spring I tested my HEQ5 with guiding. The synscan controller was connected to the computer trough the USB plug on the hand controller. This worked like a charm in my living room. On the new controllers you dont need the rs cable. But when I tried the whole thing with guide cameara for some live shooting, it just did not work. I get something wrong with the com port in decice manager, driver not working. I have tried 3 different drivers. The whole thing responded, connected and was guiding when i did a dummy test before the summer. So setup is pc-synscan via usb for pulse guiding. Can it be a problem with windows 10? What t h.... just happened? Where can I find a driver that works? And believe me it worked 5 months ago, argh. Thanks for any respons and support
  2. I was hesitant to write this earlier, but I wanted to try all possible ways to get my new SkyWatcher 250P GOTO allgined, but to no avail. I have followed the instruction manuals of both the synscan and SW, and managed to get the message "alignment successful" multiple times on the handset or the app. The closest I got when I tried to dial a different star was a 20 to 25 degrees off on the azimth axis. Most times it's off by a margin on both axes. I have tried aligning around 30 times on more than 5 diffrenet occasions, different locations as well. I end up ignoring the thing and switch to navigating manually as the eager friends want to observe instantly, but we ran out of objectes and the planets are not close anymore, so I figured it's time to get deeper DSO's and sort out the GOTO. Here is what I do: • I level the scope to the zero reading on top of the base • I make sure the base is level with a spirit level I bought recently • I point the scope northish, but latley I bought compass to pinpoint north • I plug all equipments in and then switch on the power from a lead acid battery • I enter the date ( US fromat, month before day ) • enter correct time zone obviously • the coordinates in the format of E 000 00 , N 00 00 • As for elevation I use "my elevation" app, not sure if it's accurate. Does this entry have to be that accurate? • I tried both brightest star and the 2 star align methods on the handset (which seems to be the same thing apart from the brightest method having an extra menu asking for which direction you are pointing at) I even used the synscan app and the synscan pro, and tried the 3 star align method. The app uses location and enters all data automatically •I use the top and right arrows as the last press before centring the star in the eyepiece as recommended by the manual These are the steps I follow when I align , is there anythung I missed? Your kind help is much appreciated. Update: issue solved, check the reply in the second page
  3. With several clear nights over the past week, I've been playing with the Synscan Pro app (Android) in conjunction with a Synscan WiFi adapter on an EQ3Pro mount. I have to say I'm generally quite impressed. Much cheaper than buying a traditional handset. However, this evening I was trying to "creep up" on the Andromeda Galaxy by star hopping towards it via Mirach, Mu Andromedae and Nu Andromedae. Mirach was no problem but the other stars were not available for selection in the app. Am I missing something? I couldn't find any way to enter an SAO number or any other catalogue number to find the minor stars. Is this a limitation of the app? Or the adapter perhaps? Or is it me? Clear skies, Mark.
  4. Hey, I've been looking for a mount for my 8 inch skywatcher reflector for a while now and can't decide what mount to buy. The requirements i am looking for are the following: Goto system or synscan 10+ kg weight capacity Tripod My budget is around £500. I was wondering if anyone could suggest some good mounts or point me into the right direction. My goal is to get better at astrophotography, my previous mount was a dobson mount ( which came with the scope ) but does not have any features to track objects which doesn't help when doing astrophotography.

  5. I'm trying to update my v3 handset prior to selling the mount. I need to update the bootloader from v1.0 to v1.7 before I can upgrade the firmware from 3.12 to the newest version. I've tried following the instructions in the bootloader download but the upgrade loader refuses to install anything. Before I realised I needed to update the bootloader, the synscan loader v3.3 just showed 255 255 255 where it should display the handset software, ie 3.12. Can anyone advise what I'm doing wrong? The handset won't run the mount probably because I had a replacement motor control board a few years ago., I'm guessing. It worked fine before that. I've been using eqMod for years. Thanks. Anne
  6. Recently had some bad personal news so did what I usually do in these circumstances.....I bought a new scope To be precise a Synscan 127mm Maksutov from Rother Valley Optics (no planned advert but have to say great service) At last clear skies tonight so set up my new scope, used 2 star alignment, Regulas and Sirius as my garden is only any good towards the south (street lights everywhere else), really simple, five minutes and up and running. Quick tour using handset for messiers and whipped through M46, M47, M48 and M50, followed by the Christmas tree cluster and the beehive With 25mm and 15mm eyepieces I have to say the Mak was a revelation, great views and a fun evening Looking forward to some great nights with this little treasure
  7. I have Skywatcher Synscan V3 working with my EQ6 without problem. I've lately flashed firmware v.3.39.05 and tried using it with my Skywatcher Virtuoso. I have problem with 2-star alignment. After manually move the mount to point to the first bright star, align; then choose the 2nd alignment star, the mount will slew to the sky very far away from the 2nd star. After I managed to complete the 2-star alignment successfully, the goto accuracy was very bad. It always placed my scope quite far away from the targets. I've tried the whole night and gave up. I then begin to wonder whether I have to flash the hand controller with the firmware for Allview mount (v.3.09.06) instead. Anyone can share your experience on this? Thank you.
  8. Can it be done? Without any programming skills? Yes, it actually seems that way... THIS WAS TESTED ON AN SW AZEQ5 mount which communicates with the handcontroller on a 3.3V TTL LOGIC. CHECK YOUR MOUNT'S MANUAL FOR 3.3V compatibility (should be azeq5,azeq6,eq6rpro,eq8), although I suspect it will work with the other 5V TTL logic mounts since the DT-06 board appears to be 5V tolerant, but CAN'T CONFIRM Ingredients: - DT-06 Wireless Serial TTL WiFi board - RJ45 ethernet cable -5v power supply (or 4x1.2v AA batteries) First, take the ethernet cable and cut it in half. Strip the cables and identify the cables to the corresponding pins. Then I consulted SW azeq5's user manual hand control port's pinout. In my case the pinout is as follows: pin1: orange-white ---- ground pin2: orange ----not used pin3: green-white ----not used pin4: blue ---- ground pin5: blue-white ----mount Tx to controller Rx pin6: green ----mount Rx to controller Tx pin7: brown-white ----- +11 to+16 V pin8: brown ----- +11 to+16 V Then I connected the orange-white & blue cables to the DT-06 Wireless Serial TTL WiFi board's ground pin, the blue-white cable to the DT-06 Wireless Serial TTL WiFi board's Rx pin, the green cable to the DT-06 Wireless Serial TTL WiFi board's Tx pin, and a 5V power supply to the DT-06 Wireless Serial TTL WiFi board's ground & Vcc pins (or 4x1.2v AA batteries) , I 've ordered a buck stepdown converter to utilize the +11 to+16 V from pins 7&8 to power the module, but for now I just wanted to make sure it works! Now that the hardware connections are done, we move on to the settings. Power the module and a led will confirm it's on. It is on AP mode so scan with your phone for wifi, and you 'll see something like DoitWiFi_xxxx. Connect to it (no password was set on mine). Open your browser and type 192.168.4.1 , this will take you to the Built-in WebServer where you set the parameters for the module. You will see three tabs: "status", "module", & "more" From the "module" tab's dropdown menu, select "serial" and enter the values : baud rate:9600, databits:8, parity: none, stopbits:1, serial split timeout : 200. Click save. From the "module" tab's dropdown menu, select "wifi". Here you can change the SSID name (I put Synscan), and set a password if you like (I don't). Click save. From the "module" tab's dropdown menu, select "networks". Change the "socket type" to UDP server, and assign UDPserver port to "11880". Click save. Then from the "more" tab's dropdown menu, select restart. Now you 'll have to re-join the network under the SSID name you 've given. I 've only encountered some connection problems related with the serial split timeout. I found a stable connection when I set it at 200ms at the module's Built-in WebServer, and 400ms as the Readtimeout on the synscan app. That's it, you 're set to go. Download synscan pro app and skysafari plus or pro and I 'll post the settings in those apps in my next post.
  9. Hi All I need the combined brains and experience of SGL please, I'm stuck!! I've been an astronomer for 30+ years and have had several Skywatcher telescopes over time, including my current EQ6-Pro for about 10 years. This is largely irrelevant to my post, except that I hope to convey that I'm not a total novice to getting telescopes to work as they should...although I feel like I am today. I recently picked up a very battered early-version EQ6 with 10" reflector, cheap. It hadn't been looked after well and when I first fired it up...it didn't fire up at all. No life. I noticed that the power supply wasn't suitable as it only had a 0.5A output. So after digging out a spare one from the cupboard outputting 12V 1.25A, the Synscan chirped into life. My first attempt to slew the mount was met with a horrible grinding noise and refusal to move. Needless to say, I didn't do that again. Clearly the motor/gear train was seized. So a quick look on the internet brought up the amazing website posted by Astro Baby, with step by step instructions on how to strip and rebuild an EQ5 or EQ6 mount. This kept me entertained for a couple of nights, followed by a lovely smooth running mount slewing in RA and DEC as it should. Many thanks Astro Baby! Last night was the first clear night, so I took the mount out, popped the 10" scope on (had a full respray, new finder, new focuser and laser collimation), and awaited the fall of darkness. Here comes the rub. I roughly aligned the mount on Polaris, not bothering too much for this first test. The Synscan controller is (unfortunately) running Version 2.05, which is one of the early versions that are not flash upgradable. Although I didn't realise this until after I had downloaded all of the upgrade files from OVL's website. ? When I picked the first alignment star (Capella, rising nicely in the north-east sky), the mount did something completely unexpected and slewed around to east of the meridian and pointed somewhere in the direction of Alcor! What the ...? After several unsuccessful attempts at carrying out an alignment, I gave up and looked online for any similar problems. I've checked and confirmed all of the following things are correct: Location - yep as per my Cumbria coordinates Date - yep in the right format (mm/dd/yyyy) that good old confusing American format Time - yep I tried with BST and without BST (not really expecting any significant difference) Made sure the mount was in the "parked" position (weights down, scope pointing towards Polaris) before turning the mount on Tried all sorts of initial alignment stars, but none of them were in the right area of the sky at all Unfortunately, I haven't been able to find anything on the web that offers a solution. I did wonder if I've done something during the disassembly of the mount - but I know the mount doesn't have encoders on it. I didn't see anything that looked like a counter of any kind? I don't think it can be anything to do with the power supply...surely that couldn't introduce such a wild error in pointing? It's like the handset has no idea where it is. Any help would be much appreciated. This was going to be a second mount for me, but at this rate it's going to go on the scrap heap. I did think about buying a V3 handset, but didn't want to commit another £120 in case it's something in the mount itself that's the problem. Yours hopefully Jeremy
  10. 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.
  11. I am looking at the Canadian Skywatcher website and reading about the SynScans dobonian base models, comparing them just for fun. (I always wonder if someday I'll be sitting while sketching) http://ca.skywatcher.com/product/series/dobsonians/ 8" SynScan GPS 1 548USD / 1 996CAD (F5.9) 10" Synscan GPS 1 970USD / 2 541CAD (F4.7) +545 +2" 12" SynScan GPS 3 049USD / 3 932CAD (F4.9) +1391 +2" 14" SynScan GPS 3 831USD / 4 941CAD (F4.5) + 1009 +2" 16" Synscan GPS 5 269USD / 6 796CAD (F4.4) + 1885 +2" Just looking at price, size and F ratio, I find this interesting especially for the first 3 models the 8", 10" and 12" In these deals the 12" is F 4.9, is it a big difference with a F5 honestly? With the same eyepieces I use right now with my F5, Xcel LX, Starguider, Explore scientific 68 and 82 and orthoscopic eyepieces, I don't fell any need for a coma corrector very much. If anyone ever compared a F5 with a F4.9 Also, looking at the prices, the 10" it not much more expensive then the 8", but at F4.7, I believe it needs a coma corrector which will raise the price of a few bills and you get more glass behind the eyepiece. ============ (Simulation) My first goal would be to upgrade to something I can sit while sketching and that has a tracking system, that's mandatory. The 3rd thing, the aperture has to be 8" or more naturally, It's the least important need in the 3 but it's still there. The choice is not really easy: 8": PROS: Not to heavy, generous F5.9 focal ratio, decent price, not too high to watch while sitting CONS: No aperture upgrade. 10": PROS: interesting 2" aperture gain, probably still low enough to watch while sitting CONS: F4.7, Coma corrector required 200$GSO / 400$ Baader, more lens behind the EP 12": PROS: Maximum and massive aperture upgrade, F4.9 perhaps no coma corrector required. CONS: heavy weight, perhaps too high to watch the zenith while sitting, quite expensive. if you want to share your opinion, what telescope do you guys thing is the very best of the 3 and why?
  12. Hiya, I have a problem of doing alignment with my synscan. I align my scope to polaris successfully. However when i use the hand held controller synscan to do the alignment, forget about two or three stars alignments, it was impossible for one star alignment, it suggested the stars miles away from my location, when i try to slew to adjust the possition, it wont let me too do that because the location is too far out reach. Please can someone help me ? another clear night but i failed misserably ? Winnie
  13. Hello all! After a recent upgrade my EQ5 pro is now up for sale! I'm looking for £350. for that amount you get: EQ5 Pro (good condition) - missing the polar scope cap...but doesn't affect operation at all. I have also made sure the polar scope is aligned to the mount! Tripod 1 x Counterweight Synscan Handset and Motor control box (these were only very recently replaced by Rother Valley Optics) Polar scope illuminator Cigar lighter power cable. Due to the weight, i can't really get it delivered. However I am located in Birmingham and the buyer would be welcome to collect or if not too far we could arrange to meet. This is also listed for sale on Astro buy/sell and on Facebook

  15. Hello, ive still haven’t made a decision on what telescope to buy yet ( been very hard to decide what to get ) My Max budget is £400 if I know it’s worth the price.I’m looking for something that’s relatively simple and easy to set up. I was thinking about the 200p but I think that maybe a bit awkward for me and was looking to do some sketching so a goto Mount or something similar would help. I’ve found this scope https://www.firstlightoptics.com/az-goto/skywatcher-startravel-102-synscan-az-goto.html I was wondering if anyone has used this scope or knows more information about it than I do. Was wondering how “portable” it is and what the weight is for it. I’m looking to look at most things through the telescope but not setting my expectations too high. My skies are quite good 4/3 bortle scale. And will be storing it in a garage also will be stairs so need something easy for me to carry. And I’ll be going to a field opposite my house for better viewing. Sorry for keep asking what scope to get as you can see I’m not very good at sticking to a scope . Cheers Olly
  16. I've been getting started with an EQ3-2 GOTO / Skymax 127 combo, and had a couple of queries / concerns about the mount; advice would be greatly appreciated. With the clutch released, rotating on the RA axis the mount meets resistance when the counterweight bar approaches horizontal. It's enough that sometimes the motor drive can get stuck; there's no clicking from gears skipping, but movement stops. If I undo the RA setting circle screw the resistance is gone so I thought that was my error as the manual says to unscrew when locating, but as tracking is on the RA axis and the screw would normally be tightened at that point, is this an issue with the mount? I'm not expecting to use the circle so I can leave the screw loose and it seems that it'll be fine, but I'm wondering what the issue is. I've looked at badger's teardown, but I really don't want to take it apart yet as it's new and there isn't much backlash and no slop (if I understand the term correctly). I'm also wondering whether the DEC circle is set incorrectly at the factory and needs adjusting, or is this a misunderstanding on my part. After polar aligning, I assumed that having the arrow on the side of the mount head point to 90 on the DEC circle would have the telescope pointing correctly home positioned, however with a 1 star alignment my home position was clearly incorrect, and after doing a 3 star alignment (and getting good tracking after that) and returning home the DEC circle was around 78. Using a spirit level on the head, if the edge of the mount head that's parallel to the scope mounting plate when it's tightened and horizontal , the DEC circle is around 12 (or 78 if vertical), however if the edge of the head that has the two screws that secure the plate is horizontal, the DEC circle is 0. So it seems as if the DEC circle was set based on the orientation of the side of the head that has the screws, which doesn't lie parallel to the scope mounting plate, rather than the edge that lies snug against the mounting plate. Does that sound plausible or should the DEC circle be at 12/78 when the scope is horizontal or vertical?
  17. Hi Folks, I have been happily using my new skywatcher skymax 127 on a synscan az goto mount and a question occured to me when going through the alignment procedure. Does the time between centering the first star in the eyepiece and aligning the second star matter. The reason that I ask is that sometimes the accuracy of the goto differs slightly and I am wondering could it be due to me being too slow to find the next star. I am good with constellation identifying but the star names I only know a few of the major ones such as vega, betelgeuse etc., so I have to rely on a star chart to pick a suitable star which takes maybe about an extra minute. I am wondering if the mount does not keep the 1st star centred due to setup not being fully complete at this point and obviously the earth is still rotating so the star will drift and then the reference point of this star is now not centered when aligning to the 2nd star. Everything else is always the same as I have already marked the ground where I put the tripod so it goes in the same place every time and levelled it with a spirit level. The power is supplied with a skywatcher powertank so I know its not a battery power problem and all the information is correct such as time/date, elevation, lat/long etc. It isnt massively out, so far everything I have requested has been in the FOV of my 25mm eyepiece but its just something that I wondered and also whether I could improve things. cheers
  18. The purpose of this project was to provide a sturdy semi-permanent levelled support pier for a Nexstar SLT GoTo mount. If one does not find the standard portable tripod satisfactory, the only off-the-shelf solution seems to be to upgrade to a more substantial GoTo head (with dovetail) and tripod at significant cost. If one has access to an engineering workshop, many solutions are possible, but a constraint is the non-standard bowl-like mount head with large hand knob on the underside. The solution I eventually adopted was to obtain a spare bowl head and make wooden tripod legs for it. This is a relatively simple design which can be left out in the rain or re-positioned as required. Cost including postage was about £40 for the head, timber, aluminium strip and bolts. I got the head bowl from Astroboot. Tools: pillar drill, electric router. The completed mount is pictured below. It is stiffer than the standard Stainless Steel tripod with legs at full extension, but not as stiff as an EQ-5. The wooden legs are 1.2m long with levellers at the tips. I levelled the tripod using a proper spirit level, the built in bubble serving as a check. On the first trial I aligned on the Moon in daylight and found Arcturus and Jupiter. Having the head cup already set up saves significant time.
  19. Hi, Everyone could with a little advice on connecting a my Synscan v4 to my laptop. I now how to do it and also know about USB serial adapters, what i am wondering is my laptop has a RJ11 coms port but in the Synscan V4 Manual it says you need a RJ12 port as the cable supplied is RJ12. The RJ12 cable fits into the RJ11 perfectly Is there much difference in these and could i still connect using the method or do i have to go and buy the USB serial adapter? if anyone can shed some light on this it would be greatly appreciated. Thanks
  20. purchased a skywatcher synscan ten inch dob recently...when attempting to use two star or brightest star allignment the synscan immediately shuts down and returns to initializing process after second star is selected ... Will not slew. ... 4.37 software version installed... Don't think this is an equipment problem but an error of some kind on my part... Any ideas would be appreciated.
  21. Hello, Bought and received my Skywatcher NEQ6 Pro mount yesterday along with a Skywatcher 12v 17ah power supply. This is my first goto mount (had a non computerised EQ5 previously). We've updated the firmware, balanced the scope and tried playing around with the slewing on the hand controller. The mount will only slew in certain directions and not in others dependant on the starting orientation of the telescope. Declination seems to be the biggest culprit. Also is it supposed to sound so loud when it slews/doesn't slew? Any advice would be appreciated, we are out of ideas about how to get it to work or what we could try. Thank you! Simona
  22. I've searched a few forums looking for help on this subject and wasn't able to find anything - so I'm posting here in the hope that it helps others. With the help of the Simulation Ciriculum Corp I've been able to connect Starry Night Pro 7 to my NEQ6 SynScan mount. I believe the process will be the same for earlier versions of SN7 that support telescope control. Here's how I did it First - you'll need to ensure you have all the required ASCOM drivers and ASCOM itself installed before attempting to connect to your the mount (not discussed in detail here). 1. Download the SkyWatcher driver here: http://ascom-standards.org/Downloads/ScopeDrivers.htm#synta or here http://download.ascom-standards.org/drivers/SkyWatcher(6.0.6262)Setup.exe 2. Connect your mount to your laptop via the SynScan hand controller (detailed process not discussed here) and go to Control Panel to see which port it's connected to - make a note of the number. NOTE: Do NOT put your hand controller into "PC Direct Mode" (as you would with EQMod etc.) - this will prevent connection to SN7 3. Search for "Telescope Control" in Starry Night Pro 7 > under Setup click Congifure > select the SkyWatcher driver from the drop down list (ddl) > click Properties > select the port number noted above > complete the remaining fields in the properties window and click OK. 4. Finally, click Connect The big thing to remember here is to NOT put the hand controller into "PC Direct Mode" I'm still testing this configuration, for instance, I need to update my hand controller to ensure I get full functionality out of SN7 as the SkyWatcher driver is built for the latest version of SynScan. Hope that helps, and thanks to the Simulation Ciriculum Corp. team for their help with this. David
  23. The Synscan 4 with my new mount ( EQ8 ) has strange behaviour and I am trying to find out if it is bug, a fault in the unit or a strange "feature" of the firmware. During tracking in RA the celestial declination reported by the Synscan is slowly changing even though the declination axis of the mount is apparently not moving. Has anyone else noticed this? If you get a chance could you check? In my case the problem is seen via the following steps: - start aligned scope from park - select and rotate to object using Synscan - on hand controller display the rotation angle of the mount's declination/altitude axis ( Utilities/ShowPosition/AX1 ) - whether tracking in RA or not, I have found this figure to be constant as soon as the mount has finished moving to the target. - on hand controller display the Celestial declination ( Utilities/Show Position/DEC ) - it is this figure that is slowing increasing ( ~ 5" / min ) ( note it does not change if tracking is set to "off" ). Does anyone else have this "issue"? Do you have any ideas what it could be? Note that this has nothting to do with PHD or flex of the tube or imaging system - the above is just related to the declination information being displayed ( and exported ) by the Synscan unit. Much appreciated, Mike
  24. I am trying to understand why the declination position reported by my new EQ8 - Synscan 4 hand controller keeps changing. After starting my aligned scope from Park the declination reported by the hand set ( Utilities/Show Position/ "Dec/Ra" ) slowly increases ( around 7" / minute when I first measured it ). However, the rotation angle of the declination/altitude axis of the mount ( Utilities/Show Position/ "Ax1/Ax2" ) is reported as being constant ( as one would expect if the mount is not receiving an instruction to move ). That is, it would appear that the motor is not running and the encoders on the shaft are not detecting any rotation of the mount's altitude axis however the Sysnscan reports that the Celestial declination is slowly changing. Does anyone know if this is a bug or a feature? It did occur to me that maybe the Synscan is trying to compensate for the declination drift that would result from the Polar Alignment error as stored in the controller after alignment. To test this, I adjusted the Polar Alignment to try to reduce the error and see if it changed the drift rate. The initial results do not support this - after much tweaking of the alignment, and with an indicated polar alignment error of less than 15" in either axis, the rate of drift changed but was still around 5" / minute ( whereas it should be << 1 with so small a Polar Alignment error ). Has anyone else noticed this slow change in declination reported by the mount/Synscan when the mount is tracking in RA? ----- EQ8 MC Firmware version: 2.11.04 Synscan HW version: 4.16 Synscan firmware version: 4.39.04
  25. Hi, First post - so I hope I'm putting this in the right place. I wonder if anyone can help? I've got an EQ3 synscan mount which sits on top of a concrete pillar. Despite the Rigid Pillar and good Polar alignment I get terrible Goto's and Tracking. I wonder if upgrading to an EQ5 might solve some of the problems. It seems, from the reviews, to be a much more accurate mechanism. But if I did that is there any way I could buy the basic EQ5 and use my current EQ3 Synscan motors/handset with it. Buying the whole EQ5 with synscan is horribly expensive, and having already got the synscan unit would seem a waste.
