DayStar lets you UPGRADE your filter.

DayStar knows our owners will have dozens of years of life from their filters. But what if you want a better filter later? Just Upgrade it! (Subject to availability)

DayStar is happy to upgrade your ATM filter to a Quantum - or trade in your Quark for a Quatnum. DayStar will happily upgrade your equipment.

Contact our offices for valuation of your existing equipment to apply that toward the upgrade cost.

Upgrades require similar time to repair services. Payments must be made in advance in full. We will thoroughly clean and check your filter while it is in to be sure it is performing to its highest capacity.  

Kindly note that increased production costs and subsequent price changes unfortunately do not allow us to offer new prices as trade-in value; as previously manufactured equipment was fabricated with components sourced prior to increased production costs.

• Trade-ins or upgrades will be assessed on receipt for any other additional missing or broken components.

Daystar reserves the right to decline trade-ins on products at its own sole discretion.

Special considerations for SR-127 telescopes: 

No telescope which has a scratched or damaged objective shall be accepted for trade-in.

No telescope which has had focuser modifications shall be accepted for trade-in.

No telescope which has a damaged focuser shall be accepted for trade-in.

All telescopes traded in with a hard pelican style case will be charged for a replacement case (which includes its shipping).

Additional charges may apply as applicable upon inspection of goods returned for exchange.

* HALF-BANDWIDTH: The term half-bandwidth refers to an optics industry standard of measure.  On a chart depicting the peak where light is transmitted, that peak's width is measured at the point 50% between zero and full transmission. This term is called half-bandwidth.
