The New Version of the CosmicOne SCT CoolerTM is now available!

What is an SCT Cooler?

We have been quietly shipping the NEW SCT Cooler to select customers for the last few months. The reception has been excellent.   An example email from an early adopter / beta tester:

Hi Robert,

 

I finally had a chance to use the new cooler over the past few

days.  It's awesome!  Last night, I was finally able to see the

'E' and 'F' Trapezium stars in M42.  I'd never been able to do

this before using active cooling, even on nights of good seeing.

I'm certain the Lymax helped make it possible.  I love this thing,

and I'm sure the new design will be a hit!!

 

Hope you have a happy holiday season and new year!!

 

Best,

Dean Devera

 

 

What's New About the R3 SCT Cooler?

 

  • The main body is now 3D printed
  • Lower cost - Only $99.95 including shipping in the 48 states
  • Half the weight of the previous version
  • Runs from USB port power - use your cell's backup battery pack!
  • Filters, blowers, and air ducts can be customized for special applications

 

Why the change when everybody loved the R2?   Short version:

 

They were getting prohibitively expensive to produce and new telescopes require flexibility of design.

 

Like many important accessories astronomers have come to depend on, the SCT Cooler is a steady demand, but relatively low-volume product. Anybody in the business of manufacturing will tell you: volume is everything. It controls your costs, access to raw materials, access to skilled labor, etc. It is not economically or logistically practical to make these in huge quantities and then store those huge quantities for extended periods. The price of plastic keeps going up (allegedly because the price of oil keeps going up, but it never comes down when the price of oil goes down!)  The  cost per hour for using a $1M 5-axis CNC mill keeps going up; and getting a production slot scheduled is becoming harder. Many common components - like mechanical switches, large connectors, and discrete leaded LEDs are becoming obsolete.  This is driven by regular progress - like touch technology; or being pushed out by social pressure - like the once ubiquitous cigarette lighter plug.  By moving to 3D printing, we are able to reduce our costs and the retail price. We also get incredible flexibility in being able to produce special models and models for unique telescopes.

 

A FAQ, more images, movies of SCT coolers being printed, and the full story of "How the SCT Cooler is a case study in how 3D printing can save a product from oblivion" will be published shortly.

CosmicOne SCT Cooler model R3 by Lymax

The CosmicOne SCT Cooler - or "Cat Cooler" - is a device for ventilating the inside of SCTs, Maks, and other catadioptric telescopes so that they may be brought quickly to ambient temperature.  This allows image-ruining tube currents and heat pillars to be minimized in 10-20 minutes instead of the usual 45 minutes to 2 hours.  The greater the temperature difference between the place your telescope is stored and the outside evening air, the more quality viewing time you can reclaim with a CosmicOne SCT Cooler.  The SCT Cooler has a filtered air intake and other design features which minimize the possibility of dust infiltration and direct the air flow away from the internal optical surfaces.  SCT Coolers are available exclusively from Lymax!
