Before the flaming starts let me state that I own one of these scopes (a GSOmade Astrotech/Orion now/ and many other brands), mine is the GSO 8". Most of us (that own them) know that these scopes are considered to be "Projects",, your buying the basic RC optics package and they all need work to get the best out of them, and that works includes the need to buy stuff to replace the stuff they came with (focuser for example) or stuff they didn't come with but should have (like a collimation ring), and specialised tools (like the TAK Collimation Scope) to be able to get them tuned to a point where they can be used for astrophotography. I have been fighting with mine for months now, bought all the stuff and tools, and got it collimated and star tested which required further changes to collimation. Recent imaging sessions taught me a few things, one: imaging at f8 is very different to f5 on my wonderful imaging newt. And while the greater focal length reach is nice, it brings with it a few other things to sort out like guide setup etc.
I am at the point where I wonder if it has been worth the effort just to get a little more focal length (1600mm on the RC verses 1250mm for the Newt) and that there may have been better choices to achieve that.
So who else has run the gauntlet of GSO RC setup and what have you decided about living with these scopes long term? Being a practical person I am leaning to something that is less of a challenge.
