Heavy duty mount for a 40-50kg payload and other upgrades on the scope. - Forums

Looking for your suggestions on this, please if you write a model of something do add few reasons why you are suggested it.

The telescope is a 16"/40cm F4.3 newtonian, without rings, dovetail, focuser etc. (just tube + mirrors & spider) its 31kg. The primary is a 2,5cm thick Pyrex optically excellent mirror sitting on "dobson style cell" a piece of carpet. The current focuser hole is 100mm/4" diameter and the secondary is around 150mm/6".
For the testing purposes it will be tested as is but in the future modifications will happen, such as potentially sandwich CF tube, 18p primary cell, revised spider and secondary holder and new focuser.

I recommend a 10 Micron GM 2000 HPS (50kg payload) or a 3000 (100kg payload).
They can easily handle it and no guiding needed.

I was going to get one of those but I missed my chance at the offer price and I can't really justify the outlay given my locale but if I were to go for a large sized scope this would be my choice (and much cheaper than 10Micron):

Very intrigued by this. Lots of possibilities.

Second Ruediger's recommendation for a 10Micron. My experience with my GM2000 has been, well, stellar [/rimshot]. Imaging without the need to guide is so liberating, though you may not be able to do that with a Newt OTA.

Plenty of great other choices, especially Planewave.

Definitely recommend a PlaneWave L-500 with an equatorial wedge if you have sufficient space for that setup. Otherwise an Astro-Physics AP1600 GTO with encoders.

Well Written

The 10 Micron or the Astro-Physics 1600 mount would work well. You would have to make sure that you have enough pass through space for a Newt on a PW L-series mount. That mount can also move quite rapidly so you'd need to make sure that the primary is well secured to insure that it wouldn't get pulled out of alignment. The other issue with the L-series monts is that your scope will need to be perfectly balanced about all three axis, which requires some care with a Newt.

AP1600GTO would be ideal, as would a 10 Micron 2000 GM2000. I wouldn't bother with either without encoders…

Your other option would be the Trident GTR/GTS…
