CelestronSmart DewHeater Controller 2X

El producto funciona bien, lo probé desde el software CPWI en pc y muestra todos los parámetros. El pedido llego bien protegido y rápido.

This unit is not cheap in my opinion. But Celestron did it the way it should be. I use it with the Celestron dew ring that integrates seamlessly with my Celestron Evolution.

The smart dew heater controller is a high-quality piece of equipment that does a great job. It seems to work perfectly. My only complaint is the price. With a micro PC that has far more capabilities selling for under $200, I'm hard-pressed to justify the cost of this device.

Firstly, the ONLY CON I have for this marvelous DEW Heater/Controller is that there are still no ASCOM drivers as of September 1st 2023 at 6:30pm EST. Now that this ugly disclosure is out of the way...I absolutely love EVERYTHING else about it! Celestron has full support and telemetry in CPWI and their (seriously outdated) hand controllers so all bases are covered but I would love to see ASCOM/native support in N.I.N.A. for this incredibly versatile controller. I mounted the MeLE miniPC Q3 on top of my C9.25 XLT SCT (using the inlcuded VESA mount and a Losmandy dovetail rail) and because the 4x controller has an integral USB 3.2 hub, all of myUSB devices (cameras, focus wheel, focuser) and the hand controller plug into the hub and I run a single, very short USB cable into the adjacent miniPC. The four Dew Heater ports with thermistor inputs are generous but self-explanatory and highly configurable in the software. Best part is that the Celestron software intelligently controls and monitors the dew rings rather than a DIY/homebrew setup. Next, the integrated AUX port hub (which consists of three ports) is great and does the job of the add-on AUX port accessory Celestron has sold for years.What really won me over on purchasing this gem was the additional variable DC voltage power output port (selectable on the HC and in CPWI) which future proofs this controller so when I eventually replace my miniPC, I will have the ability to adjust the power input voltage to exactly match my future PC's needs.I also love how the Controller can be used as a standalone device OR with a PC (or even the HC) for monitoring and control of parameters in CPWI.I will say once more to you CELESTRON: WE NEED AN ASCOM DRIVER/PLUGIN FOR N.I.N.A. - It is 2023, so providing ASCOM support should be the norm for astrophotography!

I've very pleased with this purchase. I made a slight mistake initially and hooked up the power incorrectly, but this thing has protection technology built in to prevent damage when a knucklehead like myself dorks up. Dont hesitate, if you have a problem with Dew, you need to get on this ecosystem.

Lost several good nights using this on my Celestron EdgeHD 8".This doesn't work as advertised. Yes, it does power your Celestron Dew ring, but runs it way too hot, even on the lowest amp setting on Auto, it runs WAY too hot, like 70F on a night that's 40F and the dew point is 39 degrees, it should be running at about 42 F. Tops.Yes I changed the settings to lowest on the Celestron software and a laptop, and I did the Calibration (which takes longer than you'd think, but it is drying the censor.)At 70F it makes stars have weird shapes in your photos, and worse yet, puts an odd gradient pattern on subs, making your data unusable.This is a known issue. Celestron needs to issue a Firmware update to deal with it. If you search on CloudyNights or the FB groups for Edge HD scopes, people talk about this.Anyone saying "it's great" is usually (or always)A. Living somewhere that's not cold and wet (I live in Pacific Northwest USA, cold and very wet.)B. Running it on Manual on Low. If you're going to do that, save yourself a lot of money and use ANY power supply or just run it for free if you have an ASIAIR or similar. (note, if you do that, start at like 5 percent and use the shield that clips on the end of the scope and extends. That actually does the job in most situations and if you need heating, it's very low heat, like lower than even a standard dew strip on full.)This with the Dew Ring could be a great system but Celestron needs to fix the controller (and also the rings, a lot of them have cold spots).

Since installation have not had a dew problem with it.

Since using this with the Celestron dew heater ring on my EdgeHD 8, I’ve had no dew problems. I’m looking forward to using it to control a heater strap on my guide scope (when not using OAG).
