Product Finder for Telescopes
SCT owners should order our non-spray formula polymer, and the best kits for a SCT are our All-Inclusive kits, the Red First Contact Regular All-Inclusive and Deluxe All-Inclusive kits. The All-Inclusive kits are the best choice for many small reflecting telescopes too since there is no prep work to contain overspray from our spray formula kits. SCT owners please watch our YouTube video for application techniques and "How Tos" when cleaning a corrector plate: Corrector Plate Cleaning. If there are just a few water spots on your corrector plate you may need to use our spot pretreatment to remove the spots. If water spots are all over your corrector plate then watch our YouTube video to remove spots over the entire corrector plate. Be aware: Do not simply flood the corrector plate with pretreatment as it is water based and will easily run past the secondary mount and perimeter gaskets and get inside the OTA.

The All-Inclusive kits include the polymer and accessories required to clean your equipment, all bundled in a single item for easier ordering.

Refractor owners don't forget to read the informative oring procedural document.pdf on our SDS and Tech Data Page and check out our oring selection to stop the polymer from flowing on or under optic retaining rings.

Watch the refractor cleaning video on our YouTube channel. This video addresses cleaning of several types of objectives such as refractors, camera zoom lenses, and cinematography lenses. (For ease of video recording, the objective in the video is removed from the OTA). If you have water spots on your refractor optics watch our latest video on removing water spots from refractor optics.
