Hi Glen, how have you been. Yes, you are correct about heavy duty and imaging but also scopes are changing there are scopes out there refractors astrographs that are extremely fast and light, and also wider field lenses are popular that said that's why my large scope stays put in the observatory. these smaller Goto mounts are costing less and working remarkably well. The Gti has 45 arc second of periodic error with autoguiding you can get down to a couple of arc seconds and extremely portable. Take Care Glen clear skies
