I bought this Sightron Alt-Az mount for my Svbony Sv48p (also from astronomy plus). Combined with a carbon fiber tripod it makes a very portable/flyable package at 6kg. I am quite happy with both, but especially with the Sightron, as it is very easy to assemble and disassemble, which makes it very easy to pack, but at the same time very solid and stable. True, there are some quirks, actually one, the azimuth slowmotion is not ideally placed, but you can put it on the other side (it's a bit wonky, but it works fine for a grab & go set up) and I saw someone who just flipped the azimuth plate to get the control out of the way of the telescope when reaching for the zenith. That's the thing about this mount, it's very easy to adjust. Most importantly, the movements, both manually and with the slow-motion controls, are very smooth. If you're looking for an easy-to-carry mount with slow-motion controls and a reasonable payload, you don't really have much of a choice, but it doesn't matter because this mount checks all the boxes with flying colors.
Thanks to Astronomy Plus for carrying this product and being an awesome online AND brick-and-mortar store !

This is a super lightweight mount that produces stable images at the eyepiece.; the 3/8 screw allows you to use it with other tripods. I highly recommend this device. Also, the people at Astronomy Plus are very very good to deal with.
