Hi, did you find out anymore about Celestrons 6" SCT's weight discrepancy, I did find that there's so many specified weights for these OTA's.
Celestron Nexstar 6SE 10lb, 4.54 kg

Celestron Nexstar Evolution 6 10lb 4.54 kg

But Rothervalleyoptics Nexstar 6SE OTA weight description says 8lb, 3.6 kg , does this mean the SLT version, stated as 8lb, is the same OTA as the 6SE and 6" Evolution version and there's no cost cutting on any version.
