DEW REMOVAL

Where can you buy the Dew Buster and any thoughts on dew removal.

thanks

Do a google search on dew buster and keating and you'll find the site. Kendrick also makes a dew control system. I agree with Gary that the best way to handle this is not removal but prevention. Either of these systems allows you to do that if you fire them up at the start of your observing session. And these systems allow you a lot more control over the heat than the hand warmers. Too much heat will lead to poor seeing caused by air currents in and in front of your scope.

I've used both dew control systems - had the Kendrick first, and then got the Dew Buster. It allows you to set the heater temp just a couple of degrees above ambient to keep the heat distortion to a minimum - and the controller automatically adjusts as the ambient temp drops. More expensive, but I now prefer it. Plus it has more outlets.

I use a 12v hair drier (RV type) to remove any dew as soon as it starts to form. I use it on the scope and the EPs. Seems that after the first dew, it is not as frequent and I usually do not have to repeat more than 2x. We are in a drier climate however and it may differ in other areas.

Rather than Dew Removal, you need to be concerned with Dew Prevention. I know it's only semantics, but really, if you allow the dew to form, you've pretty much lost the battle for the night.

I use a dew shield and the Kendrick system for Dew Prevention. Being in Wisconsin, it's pretty much required to have both.

Ken, DewBuster home page is: http://www.gbronline.com/ronkeating/default.htm Just as the others said, use a dew shield, dew heaters, a DewBuster, and prevent dew before it starts. I live in Louisiana and the dew is horrendous down here. Dew will start in the first few minutes after you remove the cap if you don't have some things in place to control it. David Moody
