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:
3 green & 2 red: Battery fully charged 11.7V
2 green & 2 red: Over 50% capacity 11.4V
1 green & 2 red: Over 20% capacity 11.1V
2 red: Less than 20% capacity 10.7V 1 red:
Less than 10% capacity 10.3V No lights: Battery empty 8.25V
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

i'd like to share with you the design, making and progress of a project my astro club endeavoring to. I'll post here relevant info in a run-up to where we got to so far.
Here is the mission: 800mm in diameter. That's it. A lot of inspiration out there but it needs to be able to do science. So it's a relatively fast Newtonian capable of tracking for tens of minutes.
So we realized that we were facing 2 projects in one. The mirror on one side and the mount on the other. Shall we start with the mount? What's the best compromise in terms of ease to build and cheap components and the chance to have a stiff yet light structure. An alt-az, like the biggest telescope! - or rather a glorified dobsonian in this case.
Any comment/suggestion is welcome!
As title. Not the best to look at cosmetically but in good working order.
Mount has upgraded latitude bolts.
Will throw in the following:
Sky-Watcher power supply
HiteCastro DC focus controller
EQDIR cable to control mount from laptop
Long UK plug mains power cable
Lovely Lords Cricket bag
Based in Kent near Maidstone.
As my GoTo is successfully finished (some cosmetic issues remain) I shoud focus my attention on planets' positions. I have proper source of information: fantastic book "Astronomical Algorithms" by Jean Meeus, thus I will sort the planets soon. But planets are not a challenge for me at this moment, they are just something obvious to do in my list.
I have another idea and ambitious plan for next project within the year: locating and tracking the ISS to be able to make a video of its fly, not only transition.
Similarly to other objects, I need some equations. I'm pretty sure they are available somewhere, because plenty websites or apps offer showing current position of the ISS.
I will use this topic for sharing a progress ot the project.
