Great scope at an affordable price.

Expertly made. With all parts fitting snugly together. Optics are awesome for the price of this scope. I bought this to use when I had limited time to view or get out my Orion XT 8" or 6i. This scope is light and very portable, as I use it on a Celestron altazmuth tripod and the whole setup weighs only about 12lbs. It gives very sharp views of open clusters, bright globular, bright nebulae, the moon and ok views of the bright planets (V filter helps on planets). It does as much as you could ever expect on an 80mm, especially at it's price. *I used to use a 114 mm f4 reflector for quick views, but no more. The views thru the 80A are much sharper and it is much easier to move about to shadowy parts of my yard, as it does not require a table to sit it on, to view at a comfortable height. This scope is also great for a travel scope, as it fits in a small hand held case and can be used, at 20x-66x on a sturdy photo tripod, with acceptable shake. I used to occasionally use 20x80mm binoculars for low power views, but no more. This scope gives comparable views with the ability to increase power, without having to crane my neck or lay on my back to look overhead. A 2x Barlow will double its power and help with increasing planetary views but it has some color on these due to their brightness (acceptable for short focus 80mm). I am very impressed with this scope for use when I don't have hours to view and don't feel like draging a 40lb scope to my yard or on a trip with me. ***DEFINITELY NOT A TOY AND THE LENSES THAT COME WITH IT ARE WORTH HALF THE PRICE. This scope is also ideal for the occasional "astronomer" as it is super easy to set up and use and does not need collmination.

A very good scope for autoguiding

A very good scope for autoguiding. I took a few pictures through it of the Orion nebula too and they came out surprisingly nice. The field is not flat, shows distortion of stars on the corners and edges but the center starts are sharp points. This is not surprising as a field flattener is normally required. The only issue I have is I can only find 2" flatteners and not 1 1/4". But given I am using it for a guide scope this really does not matter much. My only real complaint is the focuser is a little hard to use. It does have a lock screw which is nice so once you get focus right you can stop it from slipping but the focus changes a bit too much with each turn which makes it easy to get focus close but fine focus is hard to achieve it takes a very delicate touch. I was very happy with the eyepieces that came with it. The are a lot nicer then any others I had for my main telescope.
