I am ordering a 174mm mini for use as a guidescope for my SCT8 (Celestron SCT 8 + Celestron .63 focal reducer + Celestron OAG + ZWO filter wheel + ASI294mono)
But now I am wondering if instead I should get the 174mm standard (non-mini) so I can dual use it for planetary.
Is there any reason that I could not use the standard (non-mini) as my guide scope? (e.g will I be unable to achieve focus since the sensor won't go into the oag guide hole ?)
Other than USB3 are there any other diffs between the 174 and the 174 mini?
With a planet-size ROI, will the 174 mini do a reasonable FPS over usb2.0?
