HEQ5 Pro Mount altitude is very stiff

Recommended Posts

Hi I have just bought a second hand HEQ5 pro mount and I'm happy with my first outing. Just pointing the scope with the hand controller to view and track.

However now moving on to Polar Alignment for acurate tracking i have found that the Altitude was very stiff and needs a lot of effort to move. So having seen other posts were the bolts or mount are damaged I have now removed both bolts and trying to free up the mounts by regularly moving this up and down across the full travel. I have noticed that this needs a lot of effort to get started but when moving it seems to be not too bad to keep moving. If i stop for any reason it then needs the same surge of effort to get it moving again. So I still think the bolts or mount would be damaged if I used those for the adjustment. Its not that old 1-2 years and the previous owner said he had not bothered with using the polar scope much.

So my question here is should I persevere in trying to free up movement using brute force or should I take the side plates off to slacken the main bolt. The main reason I have not gone for this option is the feedback that this may damage the plastic side covers.

Any comments would be appreciated.

I can only talk from my experience with an EQ6-Pro, so don't take this as gospel. But i have to say I think this movement is designed to be relatively stiff and is designed to be adjusted using the altitude bolts rather than by hand. Once you have the altitude set to roughly correspond with your latitude it should only take a small amount of adjustment either way to get it right and you are going to use the adjustment bolts for that. With your scope and counterweights on the mount you wont be wanting to adjust it any other way.

Its binding so sounds like it needs a bit of greese. If your willing there are plenty of instructions on the net. As any mount gets used, ages etc they need a little looking after.

I can only comment on the neq6 so not sure if your mount is the same. If you remove the plastic cover on the side (not sure which side)..trying not to break them and you should find a metal shim with three grub screws that are used to increase/decrease resistance in the mount movement.

There are tons of people here using the heq5 so they will step in and put me right if I am wrong.

Having moved it with brute force to get it moving and set roughly to the 51 degrees nomial altitude. I found that the small movements were working fine with the Alt bolts, it does feel like a weak spot on the mount though and needs careful treatment.

Now I found that the polar reticule needs some alignment as it was not directly centre as i spun the mount round. I think the previous owner just kept away from this setup. So I will now need to pour over the once off alignmentment instructions.

This feels great as i'm getting all the pleaseure/pAIN of setting up a new mount for the price of a second hand setup:-)

Thanks for the feedback.

This is a great guide to aligning the reticule...

thanks for that, great ideas and since i don't have any thumbwheels I'll dig out two allen keys so that I can release and tighten at the same time.

It seems that when the bolt is extended too far into the mount the bolt will struggle to push the altitude. If it closer to the bolt hole the no trouble. So one adjustment will always be easier. In my case at 51 degrees the easy adjustment is the top bolt and the one by the polar scope is a struggle. So I have ordered to stronger bolts but I think I only have to worry about the bottom bolt. Should come this week. I' still wary of this as I think this will still but stress on the bolt hole metal as that will be new weak point as it needs more pressure to move. I saw a mod on one forum that inserted a wedge onto the internal metal tab. That looks like an elegant solution but it means taking the mount to bits to insert the wedge.

has anyone manages to insert a stregthing spacer wedge through the gap above the bolt?

Well I finally got the courage to strip this down and it was  lacking grease and so tight, I'm not sure it needs to be as tight as it was so I'll leave the end caps off for a while. Like many people I found one end  cap (the one with the alt scale) popped off easily. The other was hard to get off and I can see how the get broken. However I managed in the end by using a couple of plastic guitar pick like tyre levers and managed with minimum damage. I do think this should be improved to make maintenance easier.

      Looking to buy either an NEQ6 or a HEQ5 mount.  Im in Cheshire but dont mind paying for delivery/postage.  Would consider a good imaging scope or setup too.
       
      Thanks.

      For sale is my beloved but now superfluous to requirements HEQ5 Pro for £650
      It's in a used condition as you would imagine. I've had it for about 4 years and found great success with this mount. Ideal for those beginning astrophotography and also good for visual users.
      I'm calling it "deluxe" due to the upgrades I've had done.
      - It's belt modified
      - It's had brand new bearings and grease
      - The backlash has been expertly setup 
      - It has the latest polar scope
      - The power port has been replaced with an aviation style port which is a lot more secure
      It'll come with the hand controller and at least 1 counterweight (if I can find the second it'll come with both). The polar scope cover has been lost. The counterweight is rusty as always. There is some marring on the counterweight bar housing as shown in the photos.
      It also will come with the modified power cable required also.
      Note: the power LED sometimes doesn't illuminate but the mount is still powered (please see the photo with the hand controller).
      Collection or local delivery within Northampton

      Last week I discovered a reasonably wobble on the RA axis on my HEQ5 which ended up causing lots of double stars on my subs (i am guessing because the mount kept wobbling between the two positions.) So I did the worm gear adjustment and the wobble seems to have disappeared. I did a full slew rotation check and couldn't tell any binding/grinding (I had binding at 1st attempt but was resolved after further adjustments).
      Thanks to the clear skies last few nights, I had it running throughout the night 3 times now. My overall guiding is much better than before, averaging between 0.6 and 0.8 Total error. However, when the mount gets closer to the home position (usually after 2-3am), I seem to start having tracking issues. I have attached screenshots to show examples; sometimes it's trailing, sometimes it's double stars, and sometimes it makes a u-turn to track back to the original position.
      PHD log files from another night are here: https://openphdguiding.org/logs/dl/PHD2_logs_tych.zip
      Is this a balance issue that becomes apparent when the mount is more vertical? I'm relatively new to using this mount, so most of my previous sessions have been closer to the meridian. Or is my worm gear tightened just a bit too much and causing issues? I can't really hear anything wrong when slewing at high speed.
      Only other thing i can think of is, I sometimes get error messages on PHD but pulse command being ineffective, but these happen at other times as well without causing any issues.
      It's losing me 7-8 frames over the span of 2.5 hours, so it would be nice to get it resolved if anyone has any ideas?
      Thanks

      I know it may be a bit of a long shot but I'm looking to buy a HEQ5 Pro mount or an NEQ6 Pro or something similar. Preferably belt driven but not necessary as can happily modify it. Please let me know if you have anything! Thanks.

      After trying and failing some time ago to find a video tutorial on how to strip-down my Skywatcher HEQ5 Pro mount, clean all the bearings and gears, re-grease them, and put it all back together again, I eventually learned how to do this from various other online resources and have now created my own video tutorial. For those of you with a Skywatcher HEQ5 or HEQ5 Pro mount, or indeed an Orion Sirius EQ-G mount (which is the same mechanically), this video can help you to keep you mount running smoothly through regular DIY servicing (~every 2 years).  I hope you find it useful.  Here is the link...
