Hello,

Does anyone have experience of using both these mounts for imaging? If yes, can you advise on which you think does the best job of accurate tracking and is the az eq5 gt quiet in its native form, i.e. doesn't need a Rowan belt mod? I was going to buy the heq5 pro with belt already installed, but now I see this other mount with az capabilities as well. I wonder if there has to be compromises in its performance somewhere?

I would appreciate any thoughts. 

Thanks

Mark

Many people report that the belt mod on the HEQ5pro improves backlash and makes the mount quieter.

However, a normal HEQ5pro is still a great mount with accurate tracking as long as you don't overload it.  I can easily get 10 minute guided subs with an ED80 and ED66 mounted side by side as long as the balanced is reasonably good.  I'm sure it would cope with longer subs, it's just I've never tried.   Whilst it can be a little bit noisy when high speed slewing, it's not exactly deafening !  Tracking is very quiet.

If you are looking at using the mount mainly for imaging, the alt/az mode capability would seem rather redundant.

I hope this helps.

Thank you. I would like to do both equally. I know some people say they prefer alt az for visual observation, but I can't see why visual observing with a goto, tracking eq mount would be difficult? Regarding the slewing, I am just a bit nervous that I'll wake the neighbours if I'm changing target frequently. I've seen a YouTube video of slewing with and without belt, and the belt really was whisper quiet whereas the worm gears sounded quite loud. 

Thanks

Mark

I think if you are planning on setting up the mount in your neighbour's bedroom, or right outside their bedroom window, that might be an issue.  :icon_biggrin:.  The HEQ5pro is definitely not the quietest of mounts, but it's nothing like as noisy as a Meade.  Also, if your imaging DSOs, you'll likely be spending the vast majority of the time tracking, not slewing.

If you're really concerned about it, why not see if a local retailer or someone at your local astronomical society has one so that you can hear it for yourself.

Thank you. I have my eye on a new heq5 pro with Rowan belt mod already built in for only £120 extra cost. Every time I look at astrosell, heq5 mounts are already sold or wanted! The resell value is always pretty high too, so buying new is less risky. My finger is hovering over the trigger! Bit like Davros, if you remember him!

I think it is the high cost that is causing the finger to shake. But, I have a secondhand ED80, a Nikon D7000, knowledge of Photoshop and camera adapters etc. The mount and a lithium polymer battery are the missing links, but a hefty outlay. 

Thanks for your comments

You should be able to pick up a decent secondhand example for around £450 to £500.  But, as you say, you have to be quick and be prepared to travel.  I was checking on SGL and UKAstrobuysell twice a day for about 6 weeks and had a 270 mile round trip to get mine.

Thank you. Is this based on using both for visual and imaging?

Definitely, I am so happy to use both, yesterday I was imaging the moon, it was faster or easier for me to use az mode, I was suffering with polar alignment so I couldn't rely on eq slewing, I just used az and then tracking the moon, worked for me, but to be honest, I was also using EQMOD, after all I am happy to have dual modes anyway.

Thanks. I've heard of eqmod. How do you use it?

By using ascom and eqmod apps and a cable to connect the mount to PC, it needs some steps, you can find instructions in eqmod links if you search, I am not good in writing the steps, and I am connecting the mount eqmod to Stellarium to choose targets and control the mount.

Also, with the az eq5gt you only need a regular USB cable to connect it to a pc/laptop. You'll need a dedicated cable for the HEQ5 iirc.

I have the az eq5gt and it is an excellent mount. I've not had anything heavier on it than an ed80 for imaging, but it handles an 8" SCT for visual.

I have no experience of the az eq5gt, but I have heard good reports about it.  I am using a "non belt modified" HEQ5 and I don't think it's particularly noisy even unmodded, you should have heard a previous mount I had the CG5 GT, it was nicknamed the Coffee Grinder and I really did worry about the neighbours with that one. 

If I had to replace my mount I would like to go for the belt driven one next time, only because I hear it is an improvement in both noise and tracking.  so if its quieter than my existing pretty quiet mount it must be very quiet.

Hi Carole, thank you. It's useful to hear what you think about the relative noise. I am probably going to buy new, so if the option of the belt being already present is available, it makes sense to buy it. 

Thanks

Try to squeeze budget or stretch more so you can get at least EQ6-R or AZ-EQ6, mine has no loud noise, in fact i love its sound, feels smooth and healthy, hehehe but it is really top of quality of EQ6 mount out there next to EQ6-R or Orion equivalent.

      Setting up my new HEQ5. The same issues are present (by design) on RA setting circles on the other mounts?
      Instructions missing for RA setting circle thumbscrew
      Can the RA setting circle actually be used as a normal setting circle - it seems just "cosmetic". It's either locked or slips when free to rotate.

      Has anyone used the celestron lithium powertank (the small one, not the pro version) with a skywatcher HEQ5?
      It looks like it should be perfect but that is coming from someone who is relatively clueless
      From the skywatcher specs, it looks like the mount needs 2 amps of current, and the powertank supplies 3, so that should be good?
      It also looks like the power cable is a double-ended tip-positive 2.1 mm plug, so i assume that even though it doesn't have one of those 12V car battery inputs, it shouldn't matter right?
      (just to save people some time, i'm not going to bother with a lead battery / leisure battery / jump-start pack / etc)

      I am trying to plan out my longer term equipment strategy, rather than go for impulse purchases and would like some advice on dual mounting scopes.

      At present I have a roll-off shed with steel pier in concrete block. The mount is an HEQ5-Pro, stellar tuned and belt driven which is supposed to have an astrophotography payload of around 11Kg.  My main camera is an ASI294MC. Guide camera Lodestar x2. 
      I switch between two scope set ups.  (Weight for both includes cameras and filter draw.)
      •    ES102 with 50mm guide scope, FL=714, weight is 7.5 Kg
      •    C8 (not edge) with 6.3  FR and OAG, FL = 1260,  Weight is 8kg
      So clearly I cannot mount both on my HEQ5 Pro.
      One of the reasons for going with a fixed pier in a shed is that once set up and aligned, I can just push back the roof, align, focus and get imaging in 5 mins.  However as targets change I need to swap scopes, rebalance, rewire etc. Not a massive effort but I am wondering if I could dual these scopes and perhaps eventually add something like a WO GT71 FL= 420, weight 2.93  for the wide stuff.  So total weight around 19kg.  Then maybe in the future go for a Mono camera and filter wheel and even perhaps an C9.25 Edge pushing the weight to around 23kg. 
      To do this I would plan to buy a CEM 60    mount that claims a payload of 27.2 kg, although it is not clear if this is imaging, although I can’t see why anyone would buy one just for visual. I would then just guide with the OAG.
      So I have two questions:
      Is this a realistic strategy or would I loose guiding accuracy by loading the mount in this way. Perhaps even compared to keeping the HEQ5-Pro and swapping when necessary.  Or maybe just forget the GT71 and C9.25
      If I do go down this route, what is the best way of dual or triple mounting? I have read that mounting two dissimilar scopes side by side risks unbalancing the setup, but also that mounting the ES102 on ADM rings risks flexure.
      Any other advice or observations most welcome.
      Thanks

      I tested the tracer polymer battery over a six hour period and although the red light on the HEQ5 flashed most of the time, and more rapidly as time went on, the mount moved so that the time on setting circles changed by six hours, suggesting the mount will track OK.  (the test was carried out during the day).  I did not try to get the telescope to point in a different direction using the handset.
      1) Should I be bothered by the flashing lights on the HEQ5 mount?
      2) Is tracer misleading people by saying their batteries are 12 volts?  (they say that their discharge curves are flat)
      I found that the battery's voltage falls.  Below is from the Tracer datasheet.
      ---------------------------------------------------------- 
      Built-in Fuel Gauge - 5 colour LED fuel gauge mounted externally to show charge level. LED Status:

      1 green & 2 red: Over 20% capacity 11.1V
      2 red: Less than 20% capacity 10.7V 1 red:

      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
