Long Perng 110mm, F6, F660mm ED Doublet Refractor 

The 660mm  focal length yields an f-ratio of 6, faster than standard APO’s.

So the ED APO Apochromatic Refractor Doublet Telescope gives you brighter images, a wider field of view, and allows shorter exposures of deep-sky objects.

The 110mm air-spaced doublet lens is crafted with one element of FPL-53 extra-low dispersion, “ED”, optical glass, which virtually eliminates the effects of chromatic aberration. All air-to-glass lens surfaces are fully multi-coated for maximum light throughput. Baffles inside the optical tube, glare threads in the focuser drawtube, and a retracting lens shade/dew shield eliminate unwanted glare to deliver crisp, high-contrast images.

The Long Perng 110mm ED APO Apochromatic Refractor Telescope has a beautifully machined Crayford-type which accepts all 2” and 1.25” universal telescope eyepieces accessories. The gearless Crayford design provides smooth, zero image-shift focusing. The dual-speed focusing knobs have an 11:1 micro-focusing ratio to ensure you achieve the critical focus you need for your images.

The focuser is rotatable 360 degrees, allowing comfortable eyepiece positioning or easy image framing when you’re taking pictures.
