Dear M110,
If you are comparing a 6 inch Schmidt-Cassegrain with an 8 inch Newtonian, and the 6 inch produces better views, I completely
agree with John that there
must be something
severely wrong with the optics of the 8 inch Newtonian.....
Several possibilities suggest themselves as reasons for the severe underperformance of the 8 inch Newt:
- very poor optics of one or more components of the optical train
and/or
- very poor eyepieces
and/or
- severe miscollimation of the optics
and/or
- severe mechanical strain on one or more of the optical elements.
cheers,
Robert Lang
