Protostar Flocking Board (10cm increments, custom cut)

The blackest flocking material we've ever found!

Applying an ultra-black lining to your telescope tube has never been easier.

Flockboard is a light trap surface on a low-density plastic sheet.

Simply roll it up, then let it snap out against the tube wall. It stays in place without glue or tape.

Flockboard cuts easily with scissors or a utility knife, and also drills cleanly.

Small screw holes can also be poked through cleanly using just a pointed tool.

Typically used to line the interior of a Newtonian telescope's tube for enhanced contrast.

Made in the USA.

As a guide, use 1-2x 1m rolls for a six-inch f5 Newtonian, 2-3x 1m rolls for an 8-inch, 3-4x 1m rolls for a 10-inch and 5-6x 1m rolls for a 12-inch.

Dimensions

This is for a 10cm (3.93") long piece with a 61cm (24") width.

To order a custom length simply round the length you require up to the nearest 10cm and then divide by ten to find out how many 10cm increments to order. 

Minimum order = 10x 10cm increments (1m length).

Thickness: 0.76mm (0.030").

FAQ

Is the improvement really that noticeable after applying flocked light trap material?

On bright planets like Jupiter and Venus, you should be able to easily see an improvement in field glare surrounding the planet (assuming your original condition was a simple painted tube wall). Contrast on the moon is also noticeably improved. The improvement is more subtle on deep space objects, though the flocked paper does a good job at reducing glare from nearby bright objects like streetlights, house lights, etc.

Does dew or moisture damage the flocked material?

Protostar flocking is a completely synthetic-based material, so moisture won't deteriorate it.

Does the flocked material have good thermal insulation properties?

The flocking material is a poor insulator by itself. If you are trying to insulate your metal telescope tube, you should first line it with an insulating material (e.g., cork) before applying the flocked light trap. The FlockBoard has a better insulating property, so is often recommended for metal tube applications.

What are the light absorbing properties of Protostar light trap material?

Protostar light trap products are designed for the visible spectrum (~400-700 nm) where it absorbs over 99% of incident light. It also attenuates in the near-IR and near-UV by over 80%. (See spectral reflectivity graph above.)
