    Our new, universal flattener for Apo's was calculated from the famous optical designer Massimo Riccardi.

    A flattener "smoothes" the optical problems in the image circle  caused by  coma and astigmatism, leading to a similar perfect  image quality  as on the optical axis itself.
    The flattener Model 2 is particularly designed  for shorter focal lengths, and faster focal ratios. It currently represents the limit of what is possible.

    There is no comparable flattener with such a good apochromatic longitudinal and lateral aberration correction on the market. Other cheaper models fall short significantly , which is already obvious by their significantly higher vignetting but mainly by the drastically higher inferior lateral chromatic aberration.

    The new flattener allows a generous working distance from the thread to the focus of more than 90 mm, see attached file, so that all common accessories such as filter wheels will find space.

    Model 1 is suitable for the following Telescopes and telescopes with similar f-ratio:
    • APM LZOS Apo 105 F/6,2
    • APM Apo 107 F/6,5
    • APM LZOS Apo 115 F/7
    • APM LZOS Apo 123 F/6
    • APM LZOS Apo 130 F/6
    • APM-Riccardi Apo Doublet 140 F/7

    Delivery Times

    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. Contact our helpful customer service experts at (888-264-2244)  for more information.
