We are pleased to announce our new range of heater bands. Very well made bands with an integreated controller for temperature adjustment. These will connect directly into a 12v power supply with a 2.1mm plug, which is standard on most Skywatcher and Celestron power tanks.
If you already have a controller, these bands also come with an adaptor to remove the controller, so they plug directly into most multi channel controllers.
The range of bands are a wider fit than other bands on the market making them more effective for dew prevention.
Various sizes are available to suit most telescopes. Please select the correct size from the drop down box above.
For any compatiblity or power queries, please get in touch with us.
As a newbie to astrophotography I was starting to get frustrated with problems always costing a lot of money to remedy! The newest one was dew building up on my lenses over the colder, but humid, Winter evenings. During my investigation for dew heaters I went down the rabbit hole of power boxes and dew heater controllers to fix what should be a very easy solution. Enter the RVO heater band.These heater bands are really easy to use and do not require an expensive dew heater controller box! You just need a 12V DC power source to power the band and adjust the heat level using the scrolling wheel within the supplied integrated controller (think like a dimmer light switch). I use an ASIAir Pro (AAP) and I'm delighted to write that these heater bands plug straight into the AAP and work very well! My AAP is powered by 12V DC at 5A current which is plugged directly into mains electric (it's recommend to run this current with the AAP if you're powering many other devices). My AAP in turn powers the following devices: 1.) Two RVO heater bands (one for main telecsope, one for guidescope)2.) An ASI533MC main camera (cooling)3.) An ASI120MM guide camera4.) Power for Skywatcher Star Adventurer Pro 2i mountThe dew heaters still perform excellently despite all those devices being connected and dew is now a thing of the past Note on the sizes. I bought the smallest band size (20cm) to fit my guidescope which is the 32mm WO guidescope and I found that the strap was longer and wider than is needed. There was around 4cm of overlap (about 20% of the total length) and the width of the band (5cm) means that the lens cap and focus lock ring is almost completely covered by the strap. Not a big deal, but given that the guidescope is so small, it seemed a bit overkill to have a bulky heater band around it. I bought the 30cm version for my WO Redcat51 and this is a perfect fit and do not have any comments or concerns.When I move up to a larger telescope I will definitely consider buying another one of these bands!

These are really great Dew Heater Bands. No more expensive than others on the market, they have an elasticated band that keeps them nice and snug to the scope body, nice flexible cables with plenty of options:1) direct to any 12V supply with a 5.5 / 2.1 mm connector (Standard connector for 12V in Astro Kit.2) Normal Phono Plug connection to a Dew heater controller (again standard connectors on heater controllers)3) No need to buy a separate controller they have an in line 12V controller, so small you hardly notice it but it works fine, again use this on either type connector.If you do not already have a Dew Heater controller buy these and save the money for something else

This works well on a 127mm maksutov, even in heavy dew. I haven't tested it for de-icing in sub zero temps yet.
