Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Hello Christian, The binning plays no role in the old or new formula. It has never play a role. Set the LED calibration (old or new EndPos value) with 1x1 binning and then change to 2x2 binning. You can see that the LED disappear at the same value when you change +/- 10. I check that now with my cam...

Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Hello Christian, Concerning your post from today 15:54 ... When I set the same settings (480x300, MONO16, USB traffic = 3, 20 ms), then I can set the "Exp. (us)" value like you ~ 19999.9 with the StartPos = 10061 and EndPos = 0 ... But the start and end values are to be set with the LED il...

Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Hello Robin and Christian, "Achh NÖ!" Really ? ... all the nice (long) calculations I do are now for the "cats" (also German translation :-)) Means that the simple idea that the EndPos is "after" the StartPos is wrong (EndPos > StartPos). OK, in the past, when I test th...

Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Hello Robin and Christian, I do some analysis of the camera connection to the USB 2.0 ... I do first a manual search, than a quick analysis with my Excel/Mathcad sheets, than an automatic search of more "points" and a new (full) analysis. Here the result for the camera with USB 2.0 connect...

Re: ...improve my hitting the target!?

Hello, I had similar problem for the alignment of my EQ8 mount with different telescope. I have a finder (visual) and an electronic finder (guider). It was one or the other ... but not necessary both at the same time. The EQ8 mount alignment is much easier with a visual finder for the coarse movemen...

Re: My BATCH Script

Hello Robin, Interesting ... you update IronPython to the 2.7.11 version. I install the 3.2.6462 version. All is working properly. Do you have a look to the IronLab version ? It was, in the past, a discussion about the "simple" Python libraries missing in IronPython. Regards, Jean-Francois

Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Hello Christian and Robin, I see the last version of the driver. I install it on my old laptop (because it was the first installation on the laptop for the tests with the USB 2 connection). Now, I do not remember, if I install it on my other computers. Before solving the "stability" proble...

Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Hello Robin, I try something for the GPS master/slave mode. First ... you write each time so much that I'm interested, but not sufficient that I can do something ;) I remark some confusing things ... In IronPython, I can import "datetime" or "System". Both have an UTC function .....
