Hi there,
I don’t know if this is the right place to ask this, but here it goes.
My questions is regarding CCD observations:
Sould I choose the Celestron CPC 800 GPS to have Permanently Programmable Periodic Error Correction or the Celestron Advanced C8-SGT-XLT to have the german equatorial mount benefits ?
