Backyard Universe Upgraded Carbon Tube for Sky-Watcher 150mm Quattro Telescopes.

Carbon fibre composites, also known as carbon or CFRP, have extreme strength and rigidity, low density and a unique design. BU carbon tubes are made from different carbon fabrics. Depending on the type of fabric used and its combination, the properties of the tubes can be specifically influenced and ultimately determine the appearance and the mechanical properties.

The tube consists of several layers of unidirectional fabric, which is applied in different orientations and then covered with a 3K plain as a visible layer. The tubes have significantly higher flexural rigidity than conventional steel tubes and are also approx. 0.4-0.5 kg lighter. The original tube clamps can still be used, but the knurled screws on the tube clamps must be replaced with longer ones ( not included in the scope of delivery ) so that the tube with a 2mm wall thickness can be clamped cleanly. Soon BU will also offer suitable tube clamps for their carbon tubes.

All necessary bores are CNC milled and are already made in the tube. The surface finish consists of a wafer-thin layer of clear lacquer (matt).

Please note 1. The holes for the secondary mirror spider are 6mm and are manufactured to match the BU CNC-milled secondary mirror spiders. If you want to install the original metal spider, you must drill out the holes!

If the tube is to be lined with velour, BU also recommends using spray adhesive! We recommend 3M™ Super 77 spray adhesive.

Please note 2. There is a 1mm hole opposite the hole for the OAZ. If you attach it with M5x20 Allen screws, it will be centred precisely, and you can use the 1mm hole to align the OAZ (camera necessary)

 

GENERAL SAFETY NOTICE:

Carbon dust is hazardous to health!!! If you want to make subsequent modifications (drilling, sawing, grinding), please take appropriate safety precautions (dust protection, etc.).

Deserving CF Tube upgrade.
10 August 2024  | 

The CF tube is a worthy upgrade from the Stock 1mm thick tube. The CF tube is 2.2mm thick, so you will need longer screws to mount the stock focuser and the finder bracket. Which is clearly not stated on the product description.

The CNC machined dedicated tube rings compliments the tube well also, where you can attach to the side of the rings, including finder shoes.

CYCK Spider also fits well.

Precision engineering and fantastic upgrade for my Sky-Watcher Quatro 150P
22 October 2023  | 

Precisely manufactured carbon fibre tube replacement for my Sky-watcher quatro 150P, all holes fitting exactly where needed, advise purchasing the Backyard Universe secondary mirror spider (as I had to drill out the 4 mounting holes to fit the Sky-Watcher spider) will have to insert bushes when I probably decide on the Backyard spider. All the Same this is a vast advancement on the original steel item, also noticed less due forming. Have flocked the inside, for which I purchased 100cm x 50cm sticky backed flock sheet from FLo which was not that sticky? Suggest an additional adhesive/activator. Also roll flock onto a length of 40mm waste pipe (flock face inward) fit the telescope front shroud as a guide peel 20mm of flock backing, find the internal carbon fibre line (natural join), slick down 'with the end of the flock sheet and waste pipe' lined up against the shroud "as a guide" peel more backing and roll out the flock using the waste pipe to flatten, peel, roll, peel, roll repeat etc. This will make sure of no bubbles. Please check on adhesives/activators etc. Many thanks to FLo for extremely prompt delivery, excellent service as usual.
