SV503 102ED Telescope - SV193 Focal Reducer With SV188P Diagonals For Visual Observation
Great scope!!!!
Purchased this telescope to assist with teaching my grandson the night sky. I have several telescopes to do this, but they heavy and bulky to take out just for a few hours.
I was very impressed with the quality of the build up f this scope. Felt very sturdy and rugged. The focused moved very smoothly and I really liked being able to turn the whole focused to keep the focusing adjustment at the bottom.
I had to wait for about a month before I could take this scope out due to cloudy and rainy nights (never buy a scope during the monsoon season). Finally had a clear night in May 17th and out it went. Being under a huge light dome, I couldn’t find much, but the views of the moon were the some of the best I’ve ever seen. I’m not into astrophotography, so I have no images.
Would I recommend this product? DAMN RIGHT. It exceeded what I thought when I ordered it. Very nicely built. If you are looking for a really good ED refractor, look no further. This is the one.
