For sale is my beloved but now superfluous to requirements HEQ5 Pro for £700
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).

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?
Question, is my pier out of level if I'm trying to PA (with asiair pro) and both directions are moving when I adjust the alt bolts? I can't get the mount polar aligned.

Thanks in advance
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.
