I am thinking to get a portable and light weight telescope, here is some refractors I found.

 

William Optics z61 with field flattener 

William Optics RedCat 51

Sky Rover 60 ED APO with field flattener

Astro-Tech AT65Q ED 

 

Both WO refractors show exquisite but the price is expensive too, Sky Rover 60ED APO and WO Z61 looks no different to me but it is on a attractive price, the last AT65Q is already discontinued, but reviews are good.Can anyone share your thoughts? Which one of these are better? Or there is another better portable scope?

I have the SR 70 Quadruplet and it is a wonderful instrument. I’ve also ordered the SR 130 APO Triplet. You will be very happy with your purchase.
