SV550 Telescope, 80ED F6 Triplet Apochromatic Refractor OTA, 2.5" Micro-Reduction Rap Focuser, 87mm Back Focus Distance, Telescope for Adults High Powered, for Deep Sky Astrophotography&Visual

It's easy to pay over 5000 dollars for APO triplet refractor. When SVBony offered one for under 1500 dollars, I was skeptical. Yet, reviews were excellent. I could not pass up the temptation to purchase the SVBony 550 refractor. I could not be more please with my choice. There is zero chromatic aberration, even on the planet Venus. Images are extremely sharp. Focused stars show textbook perfect diffraction rings at high power. Planetary images are incredible. The cloud belts of Jupiter exhibit bewildering detail. Also, I love the exterior fit and finish. The focuser is extremely robust. It. can easily support the heaviest 2" eyepieces, as well as the heaviest, full frame 35mm digital cameras. If you want to enjoy top performance in a 5 inch refracting telescope, look no further than the SV550.

The build quality is superb, the optics are bright and sharp, the focus mechanism is extremely solid and smooth. The entire assembly is much more solid that it appears to be in pictures. Definitely a higher end scope. Pretty thrilled with it so far.Edit—After getting some more clear nights boy this thing performs beyond expectations, I’m imaging with the ASI2600MM pro in mono with it and wow, pinpoint stars across the entire feild, no aberration noticeable at all. This scope is the deal of the century. If you’re on a budget and looking for a very high performance APO for astrophotography then it can’t be beat there’s nothing I’d complain about. I mounted it to a Losmandy rail to add room for power supplies and my imaging computer. I still haven’t had enough clear night to really push it to it’s limits but having taken some images under less than perfect conditions the results are impressive to say the least…

Ordered the SV 550. Received it a couple of days ago. I inadvertently ordered the 80 mm instead of the 122 mm. It was my mistake.Although I had initially desired the 122 mm, I was impressed with the ease of set up and the quality of the 80 mm. I had always used Different types of scopes, including the rasa, and a couple of SC 8’s etc. . Nothing was easier than setting up the telescope with an Orion eq 26 mount. I was very impressed with the visual and a brief session of photography with using zwo 2600 color. I incorporated an ASI air, electric auto focus, Lens flattener (not a reducer), , backspacing, scope camera…etc. It was a very nice neat package that fit in my gym bag! It was approximately 14 inches long by about 9 inches high. I didn’t weigh it but I suspect somewhere around 11-12 pounds. I can now “go lighter” and feel confident That I did not make significant sacrifices. Something that I’ve been looking forward to for sometime.I think I’m keeping the 80 mm.This is an update: I ordered the 122 after having decided to keep the 80 mm as well. The 122 came double packed and inside the second box was neatly placed telescope in a well packed carrie bag.I have only set it up on the mount now but it’s like dad and little boy. Although the 122 is quite manageable, It does weigh twice as much as the 80mm but still keep it in the range appropriate for medium capacity mounts.I am putting a Dual scope mount on my AVX and will be able to use both telescopes simultaneously for camera, viewing, or any combination of both.The combination of these two triplets, ais a. great value and compared to the price of a single Rassa 8., I believe I have a true value in owning both of these scopes.

Very pleased with how it looks and feels - will test this weekend if skies are clear

Husband approved... definitely pricey in my opinion

I checked the optics when I got the item and everything looked great. By handling the item mounting it on the tripod / mount and adding a camera and other bits over a few weeks I did a final check before the clear night and I found dirt between the 2nd and 3rd elements. This scope never left my house and was never abused / dropped. Just mounting and fitting must have let fall dust that was already with in the lens cell.Svbony was good and accepted the return because it was less than 30days so good on them.

I was surprised when I looked at the moon through this. The contrast blew me away. No abberations that I could see. Stars were pin points. If this company can keep the prices the way they are people will keep coming back.

80m, I’ll return it as missing 2”insert box been open before no happy one bit PERIOD!!!!Really nice scope made used my DOB insert 2” to 1.5 just trying it out could never get the insert off for field flatener Svbony needs to have part numbers on sv550 like 1.5” 2” etc so idiots like myself can purchase the need the correct things to even use the telescope lucky I have 3 other scopesLove the sv550 80mm
