In addition, I want to find a reasonably priced 80mm OTA to replace the current one, if it is possible to find one that doesn't need the extender tube. I hope this will solve much of my guiding issues.
Any suggestions?  |
Depending on what you mean by reasonable, Bintel do a guider package with an ST80 and all the mounting hardware. You'll need to specify the OTA it is to go on to get the right dovetail and radius blocks. You can get it without the guide camera and use your QHY5.
I have one on my C8, except I have a 1.25" flip mirror instead of an extension tube.
They also have a mini-guider package. I have one of those for my other OTA, but haven't had time or weather to set it up.
