A great deep space telescope
By Jeffrey W. McClure
The Sky-Watcher Pro 120ED APO is very simply a first class telescope. I did a lot of research before purchasing and when I saw the amazingly low price on Amazon I jumped on it immediately. It comes in a first class aluminum carrying case that is well padded and includes a 2" diagonal and two eyepieces as well as the finder scope. Frankly I wish the finder had an illuminated reticle, but it is a good piece of equipment. Unlike Cassegrain reflectors there is no requirement to collimate mirrors or make other difficult adjustments. The Crawford two speed focuser works like a jewel.
My final decision was made after reading a review on an astronomy website in which the reviewer had been using an 8" Cassegrain for years and at a star party got some time on the 120ED. He realized that he was seeing both moon images and deep space images better and easier on the 120 despite the smaller aperture. He reported doing some research and concluded that between the blockage that the front mirror causes in a short tube reflector and the light loss from the extra trips though glass at each reflection, the 120ED was actually transmitting more light to his eye than was the 8" Cassegrain!
If there is a drawback it is that this scope is long. That means that in an overhead shot it is possible to have a camera or diagonal hit a tripod leg. That, of course, throws off the alignment and requires a complete new set of alignment shots. The problem is generated by a combination of the overall length and the need to extend the Crawford focusing tube, particularly when doing astrophotography. The solution is to balance the scope with the camera or diagonal mounted and the tube extended. That will move the scope forward in the mount and avoid the problem. If a person has been using a short reflecting tube the issue of scope balance is a whole new problem. The way the mounting rings are set up on this scope makes it a piece of cake. Just loosen the thumb screws a little and the scope slides smoothly up and down in the padded ring mounts. The perfectly machined and polished tube surface aids this process immensely.
Overall the scope is very solidly built from the heavy metal dew shield to the Crawford mount and tube. This is a piece of craftsmanship on sale for about half what I would have expected to pay.
