The new Vixen SD115SII no longer uses spacer plates, which leads to significantly better image quality, especially with bright stars. This means that spikes on the stars that would otherwise have been created by the spacer plates can no longer be seen in photographs. You will also be amazed when you look at the moon or the brighter planets and can observe the lunar craters in razor-sharp detail and with extremely high contrast. Also consider the ringed planet Saturn or the cloud bands on Jupiter. But of course brighter deep sky objects such as the Orion Nebula or the Andromeda Galaxy can also be impressively observed.

In combination with the new optional SD Reducer HD Kit or SD Flattener HD (not included), this refractor telescope enables illumination with a 44 mm image circle for full-frame SLR cameras.

The older ED81SII, ED103S, ED115S refractors were originally designed for the visual observer and the photographer with APS-C cameras. However, the new SD series is also optimized for the use of full-format cameras through the use of new inner panels. The large 60 mm focuser also allows heavy cameras to be attached without tipping. Furthermore, the included folding mirror allows comfortable observation even in unfavorable observation situations and also offers a T2 thread for connecting a DSLR camera. This means you can observe in degrees or at a 90° angle. The carrying handle attached to the tube clamps ensures a secure hold when transporting the telescope.
