Is the USB hub powered? If not, take it out of the loop - it will just cause more issues! 

If you need the hub, invest in a 12v powered one. It will save a lot of headaches!

 

 

It isn't - is there a model people generally use? I can't find anything that looks half decent on amazon. I'm using a Surface Laptop Pro, which is a fantastic computer other than the fact it only has one USB port (arg).

FYI - I fixed the balance issues last night, which should also help as there should be much less strain on the mount.

Thanks for the replies, they are all definitely things I’ll try.

I’ve been playing with it a bit more and think it may be a communication thing as the eqmod com logs are getting RX timeout errors. It also lags a lot sometimes when I use the slew commands on the eqmod panel. I got the 5m eqmod cable and it’s plugged into a 1m usb3 hub. It behaves a bit better plugged into the laptop direct, but still seems to have connection issue and it’s that that is stopping the tracking (I think). I’ve ordered the 2m cable from FLO now so will see if that works better. Also the mount isn’t well balanced as the auto focuser and guide scope are both on left hand side. I have a pocket power box arriving this afternoon so will see if I can get a better balance when I take it all apart again 😕 

Hi - I've not posted here before as only just launched into this hobby, although I've always been massively interested in astronomy.

I had first light on my rig last night, which is:

Esprit 100, HEQ 5 Pro, ZWO EAF, ZWO mini filter wheel, skywatcher 50ED guidscope with ASI120, ZWO1600mm Pro, Lynx dew controller w 2 astro zap tapes

A big endeavour to get that lot working from zero experience, but I love a challenge and have really enjoyed the computer side (I'm a grade A nerd)...

So - what went well... I got the guide scope in focus (was stressing about this), and also the main scope. Even more awesomely, the autofocus routine in SGP is working perfectly Filter wheel also working perfectly and I'm getting lovely smooth pics from the main camera (I've already done the flats and darks while I was waiting for clouds to clear). Final good thing (well, good-ish), is that I got the platesolving working eventually, and was able to get the scope to align from Park to the Soul Nebula and centre fine. For some reason the "number of attempts" in my SGP profile hadn't applied, so it was giving up after 1 go, but I got it working in the end.

So the bad...

I couldn't take any data because every time it finished the platesolving and started PHD2, PHD2 would start the calibration process and then halfway through, the sidereel tracking on the EQMOD panel would turn off. Obviously, that would lead to a "lost the star" error. Is there some reason why sidereel tracking would turn off like that? I'm generally a bit confused as to whether I should be controlling the telescope from SGP (i.e. unpark) or using the park and unpark + tracking button on the EQMOD panel. Both PHD 2 and SGP are setup to use EQMOD ASCOM HEQ5/6?

So at the moment I can't do anything, because there's no way of guiding without it turning tracking off

Also I was cold. Very Very Cold.
