w7ay Hey Chen, Yep I totally agree with all your saying. Having said that what really amazes me is that if we assume the the ASIAIR is both the fishing line as well as lure for ZWO, I at least would expect that it would be by far the most robust product in their entire line. Speaking only for myself it has been a two edged sword. I appreciate how it made my way into this hobby much easier than it might have been otherwise. But then on the other hand for some of us, ( me included ) it is sort of like using a small computer to solve Calculus problems without me the user, having a basic understanding of Algebra, Geometry and Trig. Personally I appreciate that I was able to skip those steps to get started, but I now better understand that there is still a need to go back and take the time and make the effort to learn those courses if I am ever going to become as proficient as I would like to be .
Again personally, perhaps because of my business background, the various issues we have seen with the Pro and Plus as well as some issues with some other of their products have caused me to put a full stop on further investments with ZWO. I stress full stop, NOT I've jumped ship......... BUT I most certainly will be testing the waters elsewhere in the near future.
If I were to guess I would assume that the ASIAIR Pro and Plus are the very face of this company. To put it another way, essentially they play a huge role in Corporate Image. As galactique so well says: for $300 I'm satisfied. But $300 does not go very far in this hobby.....
HAHA yes that video is very funny. I have not watched it all yet, but will later. BTW did you see the You Tube videos he and a few other's did about 6 months ago about some crazy game changing filter that was supposed to allow imaging during the day ? :-))) I don't know if they are still on You Tube.
Lastly, if you don't mind could you post an image of the PE graph for your RST -135? I found your post here, about a month ago that shows the PE graph for the ZWO AM5. I agree that keeping up with the first derivative change in velocity (acceleration) is key for guiding. I also agree that AM5 graph looks like it might be a challenge. Almost like at some points guiding might almost need to keep up with the second derivative of velocity, Jerk !! :-)) But I have not been able to find a RST-135 graph to compare it to. You say it's very close to sinusoidal, I'd love to compare them. Hopefully far more so than the AM5 appears to be............ Feel free to e-mail that to me if you wish if you still have my e-mail Thanks Al
