  1. Anyone have any idea where I can get a replacement counterweight bar/shaft for my EQ5 mount?
  2. My 200P just arrived and oh my God... I have been trying to wrap my head around the mount for 4 hours. The manual didn't really help so I decided to go on youtube, but again, I didn't find any good and detailed videos so I decided to ask here if there is any video or perhaps blog post that might help me set up the mount. Thank you very much! *by the way, is the EQ5 supposed to have slow motion cables? I only got 2 knobs (not cables) and I'm not sure if there is something missing or not... sorry, this is the first time I've used a serious equatorial mount or telescope. Thank you very much!
  3. Hi People, I have quite severe backlash, such that guiding assistant just gives up. It seems to be about 11 secs in total, the one time GA came back with anything, but it's about 3-4 secs if I measure it by hand. Here's some guiding. Actually, it's worse when I'm dithering. So, I tried measuring the backlash with by counting and it's about 3-4 secs. If I used PHD2 guiding assistant, mostly it fails, or it comes back with a very big number, like 11,350 msecs. I tried entering this: But then I got a see-saw mechanism, even when I dropped 8,000 to 3,000 it was the same. I've taken the motor off just now and looked at the grub/hex-screw mechanisms. One hex-screw was loose, so I tightened it to hand tight and let the grub-screw off an eighth of a turn. I'll look again this evening. I ran a three hour sequence of exposures on NGC6888 (with dither) and this is what I got on EVERY image. Amazingly, they stacked nicely. So last night I ran without dither and it was mostly OK. What I want is full dither, but to do that I need to deal with the backlash. Here's a photo of the motor and gears, most of the backlash seems to come from the top gear (ie the 12-tooth gear and its neighbour). I guess the rest comes from the worm-gear: Does anyone have any suggestions? There doesn't seem to be a belt-mod for the EQ5 as far as I can see. Maybe there are better Dec backlash compensation settings I could use. Thanks, Steve.
  4. Hi, Sorry if this has already been asked ( I think it would have been, there are posts similar but can't see the the answer I'm looking for) I have a celestron C8-N scope that came with a Cg5 mount, it's at least 10 years old and although it had a lot of use to start with it's been gathering dust the last few years. So I would like to fit a motorised goto mount to it and was considering a synscan pro3 for an Eq5 mount. Can someone tell me are these 2 mounts the same and if so will the synscan be OK for my Cg5 mount. If not are there any others I should look at? Thanks
  5. Hi Guys, Wim has wisely persuaded me to go for an eqdir cable from my RPi to my SynScan controller. I currently have a usb:db9 + db9:st4 setup to the SynScan handset (ie 3 cables connected). Can I just change the db9 to st4 to a db9:Rj45 or similar? Eg: https://www.ebay.co.uk/itm/201608325158 Plus an old ethernet cable? Ie does the pinout of an ethernet cable correspond to the pinout of the SynScan controller handset socket? Regards Steve.
  6. Can anyone help? I'm pretty much a novice at this astronomy stuff but loving the steep learning curve. I started by using camera lenses modified to use an eyepiece but after much debate, deliberation and saving up, I have finally bought my first proper telescope. Unfortunately I now have a problem. Last year I bought a second hand Synscan EQ5 mount which has worked perfectly each time I have used it. I used it about a month ago for the first time with the new scope (last time we had a clear sky). Everything worked as it should. At 2 am I parked the scope, dismantled everything and put it away. Nothing was dropped, snagged or got wet. The forecast said we might get a clear sky last night. Anticipating this I got the mount on the bench, stripped, cleaned, polished and greased the DEC axis plain bearings (hoping this might help with guiding). When finished I connected the motor controller and handset and switched on. I was greeted with the following messages: INITIALISING then CAUTION BOTH AXES NO RESPONSE. If I press enter and carry on through the menus, then everything appears to be as it should except no motors run. I have tried everything I can think of and would be very grateful of advise or suggestions. These are things I have tried, so far: Factory reset Different power supply. I have been using a motorbike battery which is giving 13.5V constantly when I switch on. I have tried two other batteries with a 2A charger connected. Continuity tested the cables from the plugs that go onto the motherboard of the controller all the way to the motors. I made up the RJ45 and RJ12 diagnostic cables suggested in the manual and the handset appears to be ok. Removed the motors from the mount to make sure that they turn freely. Replaced the RJ45 cable from the handset to the controller. Examined the motherboard for dry joints and damaged components. Assembled everything in the tripod to make sure that the earthing tab on the controller made no difference. I now feel that the problem is the controller motherboard but logic tells me that it was the mount I disassembled, so the fault should lie there. Is there anyone who has had the same problem or who has the same system that could help me diagnose the problem. I'm in North Shropshire but happy to travel to anyone who could help. Unfortunately I don't know anyone with the same mount.
  7. Hello all! I have been using my Skywatcher 8” Dobsonian for some time now, and decided I wanted a good refractor with an EQ mount as my next scope. I chose the Skywatcher Evostar Pro 80mm with an LX70 EQ5 mount. This seems to be a great scope to compliment my Dob, but I'm still getting used to the EQ mount! Found some good Youtube videos and am hoping for a clear night soon to really give it a workout! Any advice is appreciated!
  8. I need my garage back so am selling my excess mounts. 1. EQ5 motorised on both axis. No tripod this was mounted ony pier. Tracks well. £100 Collect only because of weight . 2.

Thanks for looking All Sold. mods VB please move
  9. I have an EQ5 telescope mount which i use for astrophotography. I have modified it with a motorised RA axis using a bipolar stepper motor - my thread for the build is here . I want to expand the mount's tracking ability by motorising the DEC axis and using a guide scope/camera. I generally use the mount in fairly remote locations so would like to use a raspberry Pi for portability. I understand that I'll need to use a Raspberry Pi Camera Module for the guide camera. The capability I want is: 1. guide the mount along RA and DEC axes using a guide star as feedback 2. track the mount using the RA axis only, and if possible continuously take 20-30 second exposures on the guide camera (this functionality is optional, but would assist in polar alignment of the mount) I don't want any GOTO capability. I am very new to RPi and need some help: - do I need to write code for this, or is there existing programming available for what I want to do? - is it possible to avoid the use of screens (in the field)? My preferred option would be to flick a switch to start and stop the guiding, with another switch for alignment mode (or something simple like this). - do I need to use any particular stepper motors/drivers for raspberry Pi? I'm using a bipolar stepper motor running quarter steps, with an A4988 stepper driver - is the RPi 3 Model B+ the unit I should buy? Thanks
  10. Hello, so I bought my first telescope a few days ago, I bought a SkyWatcher 200p on a goto EQ5 mount, my first general impression is that I made a good decision, it was a bit over my budget, but I bought it second hand, and 8" with goto EQ5 is a good start in my opinion so far, as I won't need to replace is really soon. So I tried observing for 2 nights so far, I tried using it from my garden, and obviously its not amazing, but I live in a relatively small city with a decent light pollution. So the first night was pretty bad, it was really hard adapting to everything, learn how to use everything, my brother ripped by mistake the crosshair in the finderscope(I fixed it today tho, it was kinda loose before, so its even better now), and it was pretty hard. Today I read a little about the things that were harder to me, I tried to align my finderscope, and even tho Im unable to do it for some reason, I know where the finderscope leads me, so its a bit easier, I learned how to use my eyepieces better, managed to use the 2x barlow lens, I still couldn't figure how to really do all the aligning correctly such as polar align etc, but hopefully I'll learn that slowly. I also tried adjusting my goto mount, but I couldn't do it because when Im trying to do the star aligning I don't know yet which stars I should use, and trying to figure where each star is in a place that you're not even sure if you can see it because of light pollution is kinda hard, so I gave up on aligning the goto and just used it to move the mount sometimes to follow an object. The only object that I really saw was mars(I think), I couldn't see it very well tho, I tried using all my eyepieces(25mm, 10mm and 4mm) and my 2x, but it still wasn't really great. Im not expecting to see anything too well obviously, but I did except to see it a bit more zoomed and a bit more detailed than sort of orange lamp light, it makes me wonder what can I do about it, what do I need in order to see mars better? Is it because of the light pollution? Maybe the eyepieces? Something maybe Im doing wrong? Again, Im not expecting to see it like hubble pictures or anything, not even with details, but just see it a bit bigger and a bit more clear, this is a photo for example(took it with my phone and 10mm super eyepiece): One more thing is about the finderscope, when Im trying to adjust the finderscope, I simply can't adjust it enough to make it accurate, I need to loosen the screws to adjust it, but eventually the screw will just go out and the finderscope will still not be aligned with the scope, what can I do about it? I have a lot more to learn and experience, so sorry if I ask really stupid questions etc, thanks a lot for the help!
  11. My apologies for the weather we're currently experiencing, completely my fault quite clearly. Getting delivered on Sunday so I can finally get out and start imaging, although the only thing I currently possess is an unmodded D5300, intervalometer, and a t-ring (somewhere.) Pretty sure looking at this there's no tracking/guiding ability at the present time, but looking to add that at a future point. With the current setup, or not breaking the bank too much more, what's the best I can hope for?
  12. I bought a used EQ5 before Xmas from a well known auction site. IT came boxed, and seemed in good condition. Due to the pitiful weather here in Caerphilly, South Wales, UK, and also to my old arthritic joints being what they are, I finally and for the first time got it all out this afternoon to look at the sun. All was going well, I managed to find it (!) and got it tracking. After about 40 mins or so, I noticed it seemed to have stopped tracking and decided to try to figure out what the issue might be (with my very limited knowledge, this means check the power) The mount was still running, and allowed me to use the direction keys on the handset to move the mount in both RA and Dec axis...up to a point. It seemed to have no problem moving the RA, but the Dec ( I think its that one) axis would move completely in one direction, but then stopped moving when it got to a particular point in the other direction. No movement at all once it had stopped though the motors could be heard running. There also seemed to be a few "clicks" heard. Im completely stumped by this and not a little disappointed about it as it would seem I have bought a defective mount. Being a total newbie doesnt help, but my guess is that the gears are stuffed. Can anyone please suggest what to do next, though Im new to all this, I have no issue with trying to fix it if anyone can point me in the right direction please.
  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
  14. Hi, I have Bresser EXOS II EQ5 mount with dual motor drive. Want to upgrade to GOTO + guiding support. Read many negative reviews about GOTO Upgrade kit given by Bresser. So wanted to know are there really such issues like incorrect GOTO, loud noise while slewing etc. If yes, then as an alternative can we use Sky-watcher Synscan GOTO upgrade kit with Bresser EXOS II EQ5 mount? Will it work? Thanks! - Abhijit Juvekar
  15. My EQ-5 (actually an Orion Sirius EQ-G) mount functions normally when the telescope saddle is on the west side. When I unlock the RA axis and swing the saddle over the top to the east side, it moves normally until the saddle is about halfway to the horizon. Then it hangs up, and I would have to force it to go further. Same outcome when the RA axis lock is closed and I try the slewing with motors. It hangs up in the same spot. Has anyone encountered this problem, or care to speculate on the cause? I am aware of Astro-Baby's strip-down guide: http://www.astro-baby.com/heq5-rebuild/heq5-m1.htm I'm hoping someone recognizes my symptoms, and that my mount is in need of an adjustment rather than a strip-down/rebuild/hyper tune.
  16. So over a week ago, i recently got my EQ5 + a GCO 6" Ritchey-Chrétien... as of two days ago, the EQ5's legs have decided to do what i call "Spidering" Completely going their seperate ways at a near 50 degree angle sometimes if i attempt to stand it straight, it was not doing this when i got it and i cannot find much about it, even with the assembly that keeps the legs in screwed tight + the bolts on the legs also tight, what on earth is possibly causing this to happen? Bought from a well known Australian Astro Retailer known as "Bintel" - This has become stressful now as all imaging sessions do not last longer than 10 seconds due to the leg drifting out destroying polar alignment.
  17. My current setup for astrophotography is an eq5 pro mount with a 200p telescope, using a canon 1000d camera, I’ve been looking at what I could upgrade to improve my astrophotos and my top priority is getting a light pollution filter and it in the middle of a city. But next I’m torn, between getting an autoguiding system and getting a new mount (heq5 or neq6 if I could find one used) I recognise I will need both eventually it’s just about which to get first. I’m that respect if I were to get the auto guider first, I would probably have to find a different way of mounting it because of the weight limit, I found a old thread that referenced mounting the autoguiding system to the counterweight bar which would not increase the weight, I see a few problems with this but for the sake of saving the weight I figure it’s a good idea. Im not sure what autoguiding kit I would get but I’ve seen that the st80 is highly regarded and probably a Astro ccd around the £150 mark. Any advice on which to get first for my setup would be appriciated and what mount and autoguiding system that is advisable. Thanks in advance.
  18. Hello All, I found a "fix" for having a damaged worm drive that I thought I would share. Earlier this year I managed to snag the RA slow motion cable on my jacket and snap the end off the brass worm drive. After reading some helpful posts on Stargazers Lounge i removed both worm drive assemblies and switched the RA with the DEC as a short term fix. It is a bit of a pain in practice as its awkward to reach the DEC knob when viewing. Last week I decided to take the plunge and buy a GOTO kit. Just before ordering I realised that the side of the worm drive shaft that is needed for the motor gear is the broken side. After scouring the net, and talking with a few shops, the end result is that it will cost around £30-35 for a new worm drive shaft and approx 4 month wait for it to arrive from China!! It suddenly struck me yesterday that the worm drive turns the scope in both directions and there was a good chance it must be symmetrical. Good news, it is!. It took around 5 minutes to take apart and re-assemble with the worm drive shaft the opposite way around. Very straight forward. I now have some brass shaft on the correct side to mount the motor gears. I hadn't seen this fix suggested anywhere before, it was only after staring at lots of pictures it become an obvious thing to try. I hope this helps someone else out there. Callum
  19. Hi all, Im living in a fairly light polluted area, and have a Skywatcher 200p on an eq5 pro mount (which does have a synscan hand controller which has an autoguider port) and ive got a webcam which ive converted to fit in a standard eye piece. My question is, when i connect it to the finder scope what wires do i need to buy to use it for autoguiding, i figure i need a st4 to usb cable, but everywhere ive looked has said i need a GPUSB device, im planning on using PHD guider but have also heard i may need eqmod and would just like some clarification on what i actually need to purchase thanks Daniel
  20. Hi all, Im living in a fairly light polluted area, and have a Skywatcher 200p on an eq5 pro mount. I've been using my phone to take pictures of varies objects with varying degrees of success ( mainly due to mounting my phone to the telescope) but ive decided id like to take imaging a little more seriously and am looking to get a DSLR with the interest of deep sky astrophotography. having said that i dont have £5k for blow on a camera and am looking to spend around the £100 mark, but dont know cameras and dont know what the best camera in my price range would be. I realize i wont be able to do too long a exposure because of my mount being unguided and it being a eq5 pro not a Heq5. any recommendations or advice would be greatly appreciated. Daniel
  21. Hi all, bit of a long shot but does anyone have a spare leg and/or a leg spreader for a CG5/EQ5 tripod? The leg clamp on mine is broken can no longer be locked extended. Thanks for looking Roy
  22. Hi everyone, I have just bought an eq3 pro. I initially plugged it in and nothing happened so I brought the cigarette lighter adapter out to the car and it began to work. Just wondering is this how you charge it or do you have to leave it plugged in while you are using it? (Newbie here) Thanks a million
  23. Hi guys, This is my first post in here and apologies if someone has asked this question already but I have searched the forum for this answer and couldn't find one. So the problem I have with my mount is that there is a few seconds lag (1-2 seconds) to control input on both RA and DEC axis when I switch the control input to the opposite direction. It happens when I use both the Skywatcher Dual Axis Motor drive kit or even the manual precise controls. There is a slight "give" in the mount when I move it by hand from side to side. It just seems sloppy, like there's too much room between the moving parts inside the mount itself. My questions: Is this "give" normal? Can I fix it? Thanks for reading
  24. Dear All! Please read everything!!! I have a big DEC backlash on my EQ3 mount near to 8000ms, and the pulse guide correction is slow and the 2000ms doesnt enough to correct this issue. So I decided to correct it with this great EQMOD project to add some new code in the backlash correction The plan was to use the slew direction to correct the backlash! WARNING!!!! this code works like the slew controls so its minimally override the DEC coordinates. Installation from zip file: 1. install AQESCOM - final version\EQASCOM_V200j_Setup.exe 2. Copy files from final version\common files\eqcontrl.dll to C:\Program Files (x86)\Common Files\ASCOM\Telescope or C:\Program Files\Common Files\ASCOM\Telescope, but make BACKUP first! 3. run EQMOD's toolbox and register eqmod.exe 4. Happy testing. In my case the correction ratio is 800 and duration is 290ms PS. Thank You for the developers to this great project!!! final version.zip
  25. I have this fairly common dual axis hand controller that I use with an EQ5 mount. It provides tracking and some slewing albeit slowly and only apt for minor corrections. At some.point I wished if it would be possible to.make some modification that would allow faster slewing. I guess it has to do with changing the number of pulses sent to the motors each time the buttons are pressed/read. I wonder if someone has done or know about a simple way of doing it. Thanks in advance
