New thoughts of a widefield rig

[Nova2000]

As my title says. I've saved up some cash. 

1-star adventurer mount 

2-samyang 135mm f2 lense. 

Will guide with qhy52 and mini guide scope 

I'm sure it's well below the payload of 5kgs. I've seen really good images with the samyang lense. 

Any advice? I've been changing my ideas on a good rig due to money

I really like this but £££ gets me down. So I'm planning budget rig

I know I can use my kit lenses also especially 55-250 for little more magnification but it's slow at f5. 6
