Mile High Astronomy will selectively accept used astronomy gear that is in good working condition for direct purchase, trade-in, or consignment.

We require a minimum used gear value of $500 for trade-ins or purchases, and a minimum of $1000 used gear value for consignments. Used values are calculated based on market research for what we expect to be able to sell your items for.  Groups of smaller items are accepted together, but individual items below these thresholds will not be considered.

Items We Do Accept

• Telescopes and Mounts from 2016 to present, clean and in good working order.
• Questar telescopes of any age or vintage.
  
• Eyepieces, Filters, Diagonals, Finderscopes, and other optical accessories.
• Current (within the past 5 years) model cameras and electronic accessories (Celestron StarSense Autoalign, ZWO Cameras, ASIAir Plus, etc). 
  
• H-alpha solar telescopes.
• Estate Collections, whose value may be discounted due to age.

Items We Don't Accept

• No broken or damaged items, or items in poor condition.
• No starter/department store telescopes.
• No cameras older than 5 years.
  
• We are generally not accepting used german equatorial mounts due to lack of current demand; please inquire as to exceptions.

Ready to sell your gear?

Send an email to support@milehighastro.com including 1) a complete list of items you wish to include; and, 2) associated photos of the items, including photos of the glass, so we can see the condition.  We will research the used value of your gear, and generally get back to you within 2 working days with a pricing quote.  

Any pricing quotes provided before final acceptance of the equipment are estimates and not commitments to accept the items. Items must be delivered to our store to be evaluated before being accepted and having final value determined. Do not ship anything to us until we have determined we are interested in your items. You are responsible for all packing, insurance, and shipping costs, including return shipping for any items not accepted.
