Guide Scope
And it has been "out of stock" for a while too.
But, over on Ebay, I see what appears to be the very same guide scope direct from China for half the price: https://www.ebay.com/itm/60mm-CCD-Imagi ... 3028905104
I have ordered astro stuff from China on a couple of occasions. It takes a little longer to get here, but it gets here, and China Post always kindly provides a tracking number.
So is there any reason why I do not want to order this direct from the folks that make them?

Re: Guide Scope
I think I may go with Gordon's suggestion of the Orion Mini.
As for flexure, this seems to be one of those things that have pros/cons for varying styles. I've read that the plunger style bracket with the Mini can have movement due to the spring pin not being strong enough, so go for the three-point rings. And then I have also read comments similar to JT's. So it sounds like things can go either way and really may depend also on how well a specific piece behaves.
Another concern, of course, is overall weight and how much of that a component will add to the setup as a whole. Seems like the Orion Mini would be better in that regard at less than half the weight of the other.

Re: Guide Scope
Yeah, the Meoptex does appear to be the same. There are several on Amazon labeled with different names. All appear to be the exact same scope.
Tom, yes indeed I do have an ST80, though I would likely have to put the OEM focuser back on there to save weight. The

From the other forum there was a thread about the ratio of scope to guide scope, might want to insure your getting the one with the proper ratio!

Keep in mind that your best guiding occurs as those Imaging scales get closer and closer to 1 to 1.

Re: Guide Scope
Since it is completely socked in cloudy for the next decade, I've been playing with the guide scope and guide cam. I've got the whole rig set up in my living room. Added a USB 3.0 hub yesterday.
Anyway, everything is talking nicely. Even tried out
Trying to help a feller out over on AF, I just hooked up mount and guide cam to the PC. Pointed the scope out of the back living room window. There is a travel trailer parked about 3/4 of a mile away. And we are in deep twilight now. Anyway, I could clearly see two gentlemen working on an ATV there in front of the travel trailer.
While I was fiddling with exposure, one of the guys stood up walked a bit in my direction, looked around, assumed "the stance", whipped it out and began urinating right there in PHD2.
I started laughing my head off and my wife and the boys came running. Fortunately, not much detail to be had but you could see the flash of the stream in the rapidly fading light. That was terrible but humorous timing.
