Instructions for ordering secondary mounts

Secondary mounts (i.e., "spiders") are custom-made for your telescope's size. Thus, it is important to provide the proper dimensional information. Please review the instructions for ordering secondary mounts, or call the toll-free number to place your order.

Methods for placing your order

Ordering online: Use the online shopping cart system for secure and convenient transactions.

Order by phone: Telephone orders can be placed at 614-375-3146. Regular business hours are Monday through Friday, 9:00 AM - 5:00 PM (Eastern Time Zone).

Ordering by mail: Mail orders to: Protostar, P.O. Box 368, New Albany, OH 43054, U.S.A. Be sure to include all the information requirements listed above if you’re ordering a secondary mount. If you are in Ohio (U.S.A.), please include 7.50% Ohio sales tax.

Payment options

Visa, Mastercard, American Express, and Discover are accepted, as well as personal checks and money orders for mailed in orders from within the U.S.A. We do not accept electronic bank transfers.

Delivery lead-times

Stocked products are normally shipped within 1-2 days of your order. Secondary mountings are custom-made, so there is a short lead-time of 1-2 weeks.

Business and educational sales with purchase orders

Purchase orders from businesses and educational institutions are accepted for transactions larger than $1,000 (US) upon credit approval. At our discretion, we accept purchase orders for smaller transactions if you expect future orders. If you would like to establish credit terms with us, please call us at 614-375-3146.

Shipping charges and methods

Most of our products are shipped using the U.S. Postal Service (Priority Mail). The shipping charge is based on the accumulated weights of the products you order, and we strive to keep the shipping charge as close to the actual costs as possible. Shipments outside the U.S.A. are sent by postal methods only.
