I am looking to upgrade my portable mount.

I have a 300mm Pentax 645 F4 ED lens which is like a mini telescope.
I intend to get the upcoming William Optics Redcat 51 pertsval F4.9 250mmm "lens".

I also intend to get my Sony A7r2 modified for Ha enhancement and use it for nightscapes as well as for deep sky widefield.

That means my Vixen Polarie won't cut the mustard.

Ideally that means a more accurate higher payload mini mount.

Skywatcher have one and Fornax Lightrack is another possibility.

What would you recommend? I am thinking it may need autoguiding but
exposures may be in the 30 second band so unguided may work out at 250mm focal length. The Polarie may be able to do it with a perfect polar alignment but its asking a bit too much. I have imaged with a 180mm before at 30 seconds and it trailed a bit but wasn't really what is needed.

I don't want a heavy GEM either as it'll be 2nd rig whilst my main rig is imaging and the dark field beckons for another rig imaging widefield.

Greg.
