Do you buy and sell used gear?

Yes! We will selectively buy or take on consignment gently used gear in good working order. If you have used astronomy equipment you would like to consign or sell, email details and photos to support@milehighastro.com for a quote!

Do you offer classes?

We did! And we will again—once we feel fully confident in the safety of group gatherings. At this time, we do not have a schedule for when classes will resume.

Do you do repairs?

Mostly no, but we are happy to take a look at your telescope and give you guidance to troubleshoot any operating issues and advise if there are repairs needed and where to potentially go for further service needs.

In our experience, a lot of what seems to need repair is actually user-serviceable, especially "collimation" (that's when you make sure your reflector-telescope's mirrors are properly aligned, giving you a sharper image when you're done).

Do you do telescope cleaning and collimation?

Most of the time, if it's "just a little dust" on the optics, they'll be fine as they are, and your view through the 'scope will still look great. (It's actually best to leave the mirrors untouched unless they're really a mess--they're easily damaged if not handled correctly.)  For more serious mirror-cleaning problems, pro cleaning is sometimes available from your telescope's manufacturer.  For small lenses, like on your finderscope, blow or carefully brush off the dust, and then wipe with a Lens Pen or eyeglass cloth. We do offer basic cleaning kits.

As for collimation, the aligning of your telescope's mirrors, there are usually good instructions in your telescope's manual. YouTube also offers many great guides for different types of telescopes. For newtonians and RCs we do offer Collimation eyepieces.
