Amazing and good good price

Fantastic Scope for the Price !

Excellent optical and mechanical quality, had a chance to use it (coupled to a Canon EOS T6i camera) on Orion M42, the Horsehead nebula and the Rosette nebula. Truly outstanding for the price.

Excelente telescopio

Telescopio completo para cielo profundo, lunar,solar y planetario con barlow. Para poner cámara dedicada planetaria es necesario un extensor para enfocar


The SVBONY SV503 ED80 f/7 Telescope is a great little telescope for the value. It is light weight making it ideal for a grab and go scope for quick setup time and use, Features dual hinged mounting rings and Vixen style Dovetail for easy mounting on most any brand EQ or AzAlt mount. SMC Coated optics. 2 Speed RAck and Pinion focus, rotating focus head. You can use 2" or 1.25" eyepieces with the supplied 1.25" adapter. Nice and sturdy construction and machining. white powder coated Aluminum OTA. Sliding Dew Shield for smaller storage when nt in use. Paired with the SV106 50mm Guide Scope and the SV305 Camera makes for a nice little Astrophotography rig at a price thet won't break the bank. Great starter telescope for someone wanting and all around use telescope for both viewing and Astrophotography. I have owned my 503 ED80 for about a year and have used it many time in my observatory. Excellent views of the planets,Moon,Sun and many of the Messier Objects. I compared it to my Meade LX85 R5 f/5.8 Refractor and didn't see a lot of difference other than the larger aperture scope was brighter. The 503 ED80 has very little Chromatic Aberration common in most Doublet Refractors. It is nearly un noticeable using a Baader Fringe Killer Filter. I have several other telescopes and I highly recommend this for anyone on a budget or to add to your telescope collection. They have a full line of Telescopes and accessories at very good prices and pretty good quality items. I own sever acc

Sv503 is a great refractor for a great price.

This is a great refractor for a great price! I'm an astro-photographer and I've had mine for almost two months. I still get excited about using it! The quality is comparable to the best on the market. The look is almost identical to that of the Williams Optics Zenithstar. Pictures don't do it justice. You can feel the quality in your hands. From the eggshell finish to the gold accents. Solid body, check. Extendable dew shield, check. Tight dual focuser, check. Quality FPL-51 glass, check. Portability, check. This quality at this price, well, worth every penny.
