SV550 80 APO for Prime Focus Photography - Connected to M48 Camera Ring

Astrophotography is a hobby that is often expensive. In search of the best value for money items, I ended up finding the SVBony range. Finding an apochromatic telescope at this price, I admit that I hesitated at first, it seemed too good to be true. I found a lot of favorable reviews on the internet and I finally decided on the SV 550 in prime focus photography kit. I received the set after about twenty days, there were still more than 10,000 km to cover... The package was very well packaged and there were no bad surprises, everything was there and in good condition. The telescope is really very well finished, a very beautiful object and all the accessories fit perfectly. The most important thing is the result: the sharpness is of excellent quality and the chromatism perfectly mastered. The focus is smooth and precise, a real pleasure. In conclusion, I am fully satisfied with my purchase and highly recommend SVBony to anyone looking for quality equipment at the best price.

Like most people likely reading this review, I was intrigued by how an 80mm APO triplet could be going for 50-75% less than all the others. I wondered if it was just bad manufacturing or if it was bad image or if there was some other hidden reason why it was so much cheaper. Still, I bit the bullet and got it with the thought that I could just return it if it was really that bad. Spoiler: it wasn't bad. In fact, it's much better than I could have predicted. 80mm f/6. for 480mm of focal length. Get that paired with the 1x field flattener and you get true, flattened 480mm images. When I first got it, I had my back spacing between my camera and the flattener off by ~8mm unknowingly, so the first images I got from it had me ready to claim to the world that I had found the flaw that caused it to be so much cheaper. The corners were oblong and not very good quality. After learning that I was wrong and putting the right spacers in, all that went away and the images I was able to capture had me shaking my head in disbelief. They are clear from corner to corner and the colors all look great.
