I have decided to sell my Cem-120 mount as i got a second hand AP 1100 GTO from my friend who got a new AP 1600 with encoders
its just under a year old bought from Altair Astro so still under two year warranty is in mint cont i couldn't miss the opportunity to get
AP 1100 GTO and let it go still waiting for pier plate for mount.
So theirs no point in keeping two large mounts after i got my dream final mount buyer will pay shipping price is 2350 pounds.
Altair Astro price without Ipolar Camera is 3250 pounds without Ipolar Camera which is 200 pounds total 3450 pounds
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
Skywatcher HEQ5PRO Tripod and Extension pillar.
There are a few marks on the tripod legs but not really noticable, the eyepioece/spreader tray has paint flaking off
But could be cleaned and repainted, it didnt bother me, but I am lazy.
I am selling as its not getting used as it should be and I find I use the excuse that it takes to long to carry it out
and setup, but in reality I think I am just losing interest.
As it is a heavy object collection from TS25 (Hartlepool) is preferred.
But if a courier collection service is available buyer pays the costs and arranges pickup I am happy as long as money has been transfered. Also I am prepared to travel a reasonable distance to meet for exchange.

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!
