    ***Read the review of the Stellarvue Optimus eyepieces by Tony Hallas in the May 2017 issue of Astronomy***
    Introducing the Stellarvue Optimus eyepiece series. This eyepiece is ideal for higher power work on planets and double stars since it is very sharp, contrasty and has an extreme 110 degree field of view. The 4.7 mm is ideal for those steady nights when you want to boost the power up on planets and observe fine details like the festoons on Jupiter. This eyepiece will do it while maintaining the high contrast that Stellarvue telescopes are known for.

    A 110 degree field of view provides the user with almost 2 times the area of an 82 degree eyepiece. When using hand driven alt-azimuth mounts this generous field will be appreciated. The eyepiece offers a generous 15 mm of eye relief and has a standard foldable rubber eye cup. Each of the eight elements are fully multi-coated, edge blackened and the lens barrel and baffles are similarly dark black. All of these factors add up to create an extremely contrasty eyepiece that is free of unwanted reflections, flaring or ghosting.

    We recommend this as the ideal lunar, planetary and double star eyepiece as well as an excellent deep sky eyepiece for smaller DSO's.

    You can estimate the deliver time to your home or business by viewing the "Ships Within" information listed with every product. This refers to the time from when you place your order, to the time it leaves the warehouse. The total delivery time for your order is calculated from the time your order is placed, until you receive it. The diagram below shows how the total delivery time is broken down into pre-ship processing time and shipping time. 

    Processing time is the time it takes from when you submit your order to when the product leaves the warehouse. The "Ships Within" time frame listed with each of our products on the website applies to this time frame. For example, if your order a product that reads "Ships Within: 2 Weeks", this means that the product typically leaves the factory within two weeks. If there will be any additional time required to process your order, we will notify you immediately to confirm the delivery period. This time is needed for products that are shipped to you directly from our manufacturers. The manufacturers need this time to fulfill your order. In some cases, the items are custom built.  Shipping time is measured when your order leaves the warehouse to when it arrives at your address. Actual shipping time can vary between 2-5 business days.
