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...
This is my first post. I'm quite new at astrophotography, although I've used a startravel mount together with a camera for a couple of years. I recently decided to upgrade to a skywatcher heq5 pro mount which I intend to use with a Ed-80 refractor, also from skywatcher.
I've been spending countless hours trying to solve my problem and I am now to the point where I think my équipement is faulty and needs to be returned to be checked. Before I do, I wanted to ask you guys for advice because I can not exclude the possibility that I'm just doing things wrong. Here is my problem :
The mount does not track even though I've done the polar alignment and hooked on the synscan handset. I initially believed I would not need the handset for simple tracking and that after polar alignment, the mount would automatically start tracking. Clearly it did not, as the mount did not move and was completely silent. I then hooked on the handset, entered all the info for initialisation, checked the sidareal tracking was checked, but still no tracking, even though the mount did make some noise at that point. I did try to align one or two stars, but the telescope would just be way off the targeted star. I mean totally way off, sometimes pointing the opposite direction. I gave up star alignment, so just skipped the alignment part, thinking I could still use the mount to track without star alignment. However, when pointing to a star, I would see it drift after a few seconds, so clearly no tracking.
Can somebody help me out?
Questions: is it possible to use the mount to track without any star alignment, or without using the synscan handset? Is there an on/off button somewhere I have missed to start tracking?
Any idea why the star alignment is so incredibly off target? I doubled check all the gps, elevation, date info and the polar aligment is accurate as I checked it after a couple of hours and polaris was exactly where it should be according to my Find polaris app.
I'm quite desperate now, so any advice is more then welcome!

Hi, I recently made a video of how to mount a Sesto Senso focus motor to a Starlight feather touch focuser.
I have now also made a video of how to calibrate it and also how to measure the backlash of the rack and pinion gear of the focuser.
This method is not limited to a starlight feather touch focuser but could be performed on all kinds of focuser.
I hope this video makes it easier for anyone out there having problems with backlash.
You can also check out my other videos of the focuser / focus motor here: https://www.youtube.com/channel/UCm50WzpT1YKCwghW13b6k-g?view_as=subscriber
