Dear all, 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! Thanks. fred
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.
Last night whilst using my Skymax 127 Synscan, I was having trouble completing the 2-star alignment. I aligned the first star no problem, but when I selected the second star to align (Polaris, Capella or Aldebaran, it didn't matter which one) the scope slewed upwards and point towards the zenith. This was only my second time using the scope. The first time I used battery power and everything worked fine. Last night I was using electric through an extension lead. Thinking this was the problem, I reverted back to using batteries, and the 2-star alignment went perfectly. Then, after about 45 minutes viewing, I attempted to move the scope the short distance from Jupiter to the Pleiades, and again it slewed right up and looked like it was going to keep going beyond the zenith to point in the oposite direction to where the Pleiades are. I stopped the scope at the zenith, and tried to move it using the direction arrows, but it wouldn't do anything. Does this sound like a problem with my power supply, or does it sound like something more serious ? Thanks Kev
