I have had so may dovetails over the years, rated from dire to works OK.
Well that was until I bought the 280mm for the recent to me Vixen SD103 scope I purchased.
My old ED103 had slipped from a mount last year, so dovetails were something I am rather sensitive to, as are stop screws* more on this.

The More Blue is very well made, very well finished and well designed so lighter than many but super strong due to good design, not brute force.
The More Blue also has two holes each end for stop screws to stop a slipping scope sliding out of a mount.....just like my old one did that had no stop screws! and to be clear it was not on a More Blue dovetail, it was an another well rated manufacturer sold by FLO and others.

Really pleased with the quality and the well designed and supplied small stop screws.

As usual FLO service is as reliable and excellent as ever, a service level that I now judge other buy, not just in astronomy.

One of the lower cost options but looks and feels quality. The slots provide a lot of flexibility for adjusting camera and OTA support. Ideal for my ASI1600+Filter+Samyang 135mm rig.
The inclusion of 2 M6 hex bolts + square nuts for the underside recessed channel and 4xM3 end-stop bolts was a nice touch.
