A google check on this Seben scope shows what appear to be a Jones-Bird compact Newtonian with Barlow like lens near eyepiece to correct for the simple spherical primary mirror. The design can work but I've yet to see a good commercial version.
I own a Meade DS-2114s [of similar design] that I've converted to an astro-camera to good effect
