    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.

    APM 20XWA eyepiece

    This eyepiece is a keeper. Produced, nice sharp views of the planets to the lens edge and the wide field of view is amazing. This eyepiece is fairly heavy but still lighter then other brands with equivalent focal lengths and FOV. I ordered this eyepiece after doing much research on the forums over top eyepieces. I will have to say the reviews of this eyepiece were spot on.
    On a side note, doing business with Nick was very honest. Ordered this lens with another APM product and he called me the next day to inform me these wont be in stock for a month and offer a full return if I didn't want to wait. I chose to wait and he kept me informed and updated till the moment the order arrived at my door from Germany. Thanks Nick. We will be doing business again in the future.

    APM XWA 20mm 100 Degree EP

    I love these eyepieces. I observe thru a Stellarvue 102 Access with a Strehl of .983. These EPs do not take anything away from the optical train. Recently observed Mars, Saturn, and Jupiter. Seeing was very good. Moons and detail were excellent on Saturn and Jupiter, detail was excellent on Mars. If you are comparing to the Televue Ethos, I can't see where 2.5x the cost gets you. These are very clear to the edge and they disappear in the view, like an excellent eyepiece should. I've owned many different EPs in my 17 years of observing the night sky, and these are by far the BEST $250 I've ever spent on an EP! Thank you APM!!!!
