I just recieved my new QHY5 guidecamera, tanks Gamma.
First impression - what a small, light neat package, just right to pop on the WO66 and is barely bigger than the 2" draw tube and light too...
Second impression, well this is no surprise, but the configuration of the camera is tricky. It can be configured to be one of several models depending on the software you intend to use it with (in my case PHD and Guidemaster) so you need to learn a bit more about USB than you probably care to but after some futzing around I had it working with PHD...so let's get it under the stars...
And very happy...with a 2 sec exposure I have potential guidestars all over the fov (which is 48'x60') looks like I can go to Mag 10 - maybe lower and high resolution gives me good sensitivity (2.8" per pixel), sub pixel guiding means I will be limited by seeing but I should easiliy get down to 1".
I still have some USB issues to resolve - but I did 2x10min guided runs on a mag 9.5 star with subpixel accuracy - something I have not been ble to do before so it is a good start...that is Acrux in the middle of the image...
