That was a detailed response to the OP but do you mind naming the cameras and what went wrong with them? It will be a great here.
Easy enough, read my signature.
I got an Orion G3 color camera.
1. The first one the fan didn't run. Not finding anyway to make it run, I called Orion. I asked the guy how to turn on the fan. He said it comes on when plugged in.
I told him it doesn't run. After I talked to him for a couple of minutes, he had a moment finally. Wait, he said, the fan has never run? Yep, the fan has never run so I'm calling to find out how to turn it on.
(By this time I'm wondering if he knows as much about the product as I do.) He sent me a new camera, and instructed me to take the new camera, and return the bad one.
2. The newly replaced G3 fan ran. But it had striations through every crappy picture it took. I worked with it for 8 months. Finally, end of warranty closing in, I sent it back. They sent the third G3....
3. The third G3 fan ran, and no striations in the image. (Be cause #2 had a half dead matrix. Such quality control...NOT.) Now, Camera #3 was noisy. So much so, 5 friends tried processing the images from it. None could. So what I did to make it half-fast work was to take long exposures. No, I mean L-O-N-G exposures. Most were 20 minutes to 30 minutes one-shot-color images. But one night I got some bang-on tracking and guiding. I worked my way up, and up, in time. Finally, I just went for it 5400 seconds. 90 minutes, single shot, color image. And it worked.
The cooler on it never got real cold. 10° below ambient was a good night. My friends used to tell me, Sonny, you just stack with time. And we had a standing LOL about my "Rainbow Sprinkles" in every image.
Finally, a friend offered to loan me an Atik Infinity OSC camera. I resisted, he persisted. Finally, I accepted after I told him, What if I do let you send it. And what if I like it? Or what if it gets lost in the mail? What if I like it and want to keep it?
He said we could work it out, and insurance would cover it if it got lost.
He sent it, The very first image, the very first night, was the proof the G3 was a terrible piece of crap.
If you go, again, to my signature, and the bottom line, there is a link to a video I made of my first 6 weeks or so with my Atik Infinity.
But, I'm not one to blame the equipment until the equipment itself proves it is garbage.
My AVX, and the G3 both proved they are trash. See the strike through? See the replacements after the strike through?
Now, see my face? That's because I've corrected my beginners mistakes.
