UPDATED - 8-inch f/6 Primary Mirror – QSP Optical Technology - Free Shipping CONUS

I have an 8-inch f/6 Newtonian primary mirror available for sale.

The mirror is marked "F6" on the back and carries a label from QSP Optical Technology, Inc. of Santa Ana, California. Diameter is approximately 8 inches and thickness is approximately 1.25 inches.

The mirror appears to have been professionally coated and center-marked. I do not have any documentation regarding the optical figure, wavefront accuracy, or original telescope application, so it is being sold as an unidentified 8" f/6 primary mirror.

Condition:

• Coating remains reflective and produces a bright image.

• Reflection photos of distant objects are included in the listing.

• Some coating degradation is present, including scattered pinholes visible during a bright backlight test and a small area of edge coating loss.

• No chips, cracks, or significant scratches noted.

• Optical surface appears clean overall.

• Sold as-is due to unknown optical pedigree and lack of test data.

This would make a good candidate for:

• ATM telescope projects

• Restoration of an existing 8" f/6 Newtonian

• Testing, experimentation, or eventual recoating

Included:

• 8" f/6 primary mirror only

• No cell, secondary mirror, or other telescope components included

Price:
$199 OBO

Price includes:

• Shipping within the Continental United States (CONUS)

• Shipping insurance

• PayPal fees

Payment:
PayPal preferred. Other payment methods may be considered. Please contact me with any questions or requests for additional photos.

Thanks for looking.
