About OPT

People come to OPT because we have the expertise and equipment required for understanding and engaging with the universe in a tangible way. We are and will continue to be the primary source of information and supplies in the industry.

Like many others, we come from humble beginnings. Once a sleepy camera shop in Oceanside, CA, we have since grown into the largest telescope retailer in the world. Chances are if you’re involved in astronomy, you’re involved with us, and we’re happy to work with you.

Whether you’re a professional, high-grade institution or an amateur just getting started, you’ll be treated with the utmost respect you deserve. After all, each of us is part of the OPTeam, we’re just in different offices. We are The Telescope Authority and we want you to be, too.

Chronology of OPT

1947 - Founded by WWII Flying Tiger Pilot Donald Penning as “Oceanside Photographic Center.” Mostly sold camera equipment to Camp Pendleton.

1977 - Moved to a larger location to match the growing business needs.

1985 - After first entering the telescope market a few years prior, the company experienced great success and officially changed its name to “Oceanside Photo and Telescope.”

OPT entered a new stage in life.

1988 - The telescope side of our company continued its rapid growth, prompting yet another move to a location on Mission Avenue in Oceanside. Here we could accommodate the tremendous increase in sales and inventory necessities.

1994 - OPT website is created!

1999 - Continued growth in the telescope and camera markets bring on the need for OPT’s first full-fledged warehouse to manage its massive inventory. This same year the company website became officially recognized as an e-commerce website, undergoing a series of additions and improvements to better the customer experience!

2007 - Moving again! We moved across the street from our old location to a building that could house all employees and inventory in one spot. This was a welcome and convenient change for everyone.

The annual OPT-hosted Southern California Astronomy Expo (SCAE) continued with greater success for another ten years just outside the building. Community engagement with astronomy and industry leaders only got better with this new location.

2016 - On September 1, after being employees for just shy of one year, Dustin and Ginny acquired OPT, becoming the new owners. The two of them being avid astrophotographers, they embrace the hobby, the industry, and everyone involved.

With their leadership, a revised and revitalized vision spread through the company. Dustin and Ginny strive to engage with any and all that are interested in the universe around us and to invite amateur and professional alike into the OPTeam. Our goal is to make it easy for anyone to experience the cosmos to their heart’s content.

The universe is all our home, and we hope everyone feels at home with OPT, too.

2018 - On September 1, we moved for the last time (for now) to our current location in Carlsbad, California, just a short drive South of our previous spot. We may no longer be in Oceanside as our longstanding name states, but rest assured, we’re still OPT and we’re only getting better.

This new building grants us four additional shipping bays, helping us deliver your gear as fast as possible. We can now hire more staff to provide an even better customer experience; we can work efficiently and effectively with the interconnected office & warehouse design; we have a dedicated studio to produce our Space Junk Podcast each week. We have everything needed to provide you with only the best products and services.
