Well, sure. Things change. Some people prefer some of those changes, and some don't. Personally, I live in a part of Texas where relative humidity averages 90%. If I want to observe all night, I'm bringing a hair dryer or something like this. The hair dryer works great, but at 1200W it won't run very well on a battery, so then I need a generator. The reality is, the system in this video is much more convenient. Mount it all once, and you're basically done. I used Kendrick Astro's dew heaters before that, and they worked great. But I wouldn't call them any more intuitive. And if I'm not travelling and wanting to get in a ton of time, one of many manual scopes comes instead, and all of the sudden I'm living with "astro gear and viewing" that are 40 years old. I enjoy that too.
I have this installed on my nexstar evolution 9.25 and it was a breeze to install as long as you don't remove the retaining ring and literally torque the corrector plate you will be good. Been waiting for the update so I can use the ring. I live in an area we're there is a lot of dew and I. Excited to use this.
Very informative video, especially if one is using an all-Celestron rig. It would be nice to see some guidance on how to manage the dew controller via ASCOM drivers and NINA.
Does Celestron make Dew Heater straps for refractors that are equipped with the same control and sensor technology? In other words, are there dew heater straps with the sensor capability as well as the power cable?
This is excellent presentation. The HC you used - does it come with the dew controller set ? If you don’t mind can you please let me know all the cable names used… they are so confusing when we hear them first time. Appreciate your time and thank you
This new product looks very enticing. I live in a very humid environment and have blown out two dew straps so far. Plus, I like the idea of controlling it via CPWI. This will certainly be placed on my wish list.
Yessir. Not mount-specific at all. Thought you may need to be clever mounting the dew heater to your rig, depending in the mount. Be aware that if you want to power your mount from the dew heater to reduce cabling, your mount will need to run on 12V or less. Also, I think the accessory ports on the dew heater probably only work with Celestron accessories like the WiFi or GPS module. I'm not at all up to date on how this works with other mounts, though I do know Synta manufactures both Celestron and SkyWatcher. You might get lucky. The folks on the Cloudy Nights forum will know for sure.
What about the dew sheald for stopping stray light? Mine has the dew hearter built in it. If I get the dew ring I would still want to stop the stray ligh with the dew shead unpluged. Can that be done?
Does this Celestron dew heater work with a Celestron EdgeHD 925 when NOT on a Celestron mount? I use the iOptron GEM 45 mount with my EdgeHD925. Will the heater work with this mount with or without the ASIAIR Plus? Also, have you used it in the field and how effective was it to prevent dew?
Hello Michael, 1) You can power the dew heater and control the dew temperature through other non-Celestron controllers like Pegasus, et cetera. You can also power the heater directly from a 12v power source without a controller. 2) You cannot use the iOptron Hand controller to control the dew heater system. 3) The ASI Air can power the dew heater ring, but unless it has the ability to control the temperature, it will operate at 100%. 4) Teagan was not able to use it in the field as he did not encounter any dew.
@@highpointscientific It can control the power output to a dew heater via PWM. So you can run it 100% or dial it down if you need less. But yeah, nothing more complicated than that.
Hello David, the Pegasus Astro DewMaster can control five dew heaters at once, but it does not appear that you can control it through software in the same way you can with Celestron and CPWI. The DewMaster could also control the Celestron Dew Heater Ring through one of the RCA ports.
@@highpointscientific these differences are true, however for a visual rig SW control is unnecessary. How about a comparison with the PegasusAstro PPB series? I'm in the market for a dew control system for my Celestron CPC Deluxe 800, which is a visual/EAA/planetary rig only (no AP). A dew controller with a built-in control loop with a thermocouple, RTD, or thermistor is perfectly fine and I think a better solution than a dumb solution with potentiometer control, no SW control needed as it will throttle power to the heaters on its own. Not sure which route to take for a dew controller, in the meantime I use a low-tech hairdryer solution.
But there are still so many cables and connections. I thought that they would have come up with something more simple, like one or two cables or connectors.
Ugh. Removing the ring on the corrector plate to replace it with the dew heater makes my skin crawl. One little accidental nudge and you're in for a world of issues.
40 years ago, astro gear and viewing was so simple. Today, you need youtube to explain so many necesary system installation and operation.

We're glad you found it easy to install! Thanks for the feedback!
Thanks man. Great video for newbies

What do you do with all the cable? it looks like the back of my stereo

Celestron doesn't sell dew heater straps, but the Celestron Dew Controller should control dew straps from other manufactures like AstroZap, et cetera.

Looks great, too expensive for my blood, but looks cool!
Do you have to use the Celestron dew heater ring? can you use any dew heater straps?
In my previous reply, tub should read tube, and the second 6” should be 8”.
Hello! You should be able to use any dew heater provided it has an RCA cable.
This new product looks very enticing. I live in a very humid environment and have blown out two dew straps so far. Plus, I like the idea of controlling it via CPWI. This will certainly be placed on my wish list.
We agree CPWI control is an amazing feature!
Will the dew heater work with skywatcher or other mounts?

Yes! The dew ring should not interfere with the dew shield with the integrated dew heater!

4) Teagan was not able to use it in the field as he did not encounter any dew.
Could you control the dew ring with the ASIAIR?
Should be able to. The AIR's power ports just send power, they don't look at brand or anything. There's really not a lot of electronics involved here.
The ASI Air doesn't have dew controller settings, but you should be able to power it either on or off via the ASI Air.
@@highpointscientific It can control the power output to a dew heater via PWM. So you can run it 100% or dial it down if you need less. But yeah, nothing more complicated than that.

"12 volt output port" 🤣

Yes, you need to be exceptionally careful not to nudge the corrector plate when installing.
na piece of cake just take your time and watch the video @@highpointscientific
