SIEBERT OPTICS (continued)
10 x 35mm VIEWFINDER
This is the 10 x 35mm viewfinder. It utilizes an all achromat lens system for superior color and light correction. The eyepiece for this viewfinder has an extremely wide apparent field of 65 deg. 35mm is much larger than most standard spotting scopes for most small telescopes. The standard being roughly 25mm. This means extra light gathering ability and a brighter backdrop for the reticle or crosshairs. The tube and assembly slide apart for easy installation. This also comes in a straight thru version also.
This also comes in an 8 x 25mm straight thru or 90 deg. diagonal version also.
6 X 50mm FIBEROPTIC ILLUMINATED RETICLE VIEWFINDER
This is the 6 x 50mm laser illuminated FiberOptic Viewfinder. The picture to the left is the straight thru version and the picture on the right is the 90 deg. diagonal version. Your working distance from the eyepiece on this viewfinder is from 1.5" to 4". This gives you a tremendous amount of latitude as to how you use it. Even the side to side motion is very forgiving. So you don't have to plaster your eye to the viewfinder to line up your scope. All lenses a fully coated for maximum light transmission. It has a 50mm objective so it captures an enormous amount of light, as much as a small telescope. And being this has 6x magnification means you take in a large amount of the sky (roughly 10 deg. at a time.) This is made out of an all metal construction with a 50mm achromat objective and a 27mm achromat composite eyepiece. The third element being a field widener and light and color corrector. This uses a red laser light on a fiberoptic cable to illuminate the crosshairs, so that on a very dark backdrop you will see just enough of the crosshairs to be able to line up your scope where you want it. The red light will not diminish you eyes light sensitivity. It has a remote reticle light actuator so that you will never have to touch the viewfinder at any time. These both come in straight thru versions also.
