For those who can’t wait to observe, this handy accessory cools the primary mirror to the ambient outdoor temperature faster. The result is crisper, better-focused views sooner —and more time for you to observe. This cooling fan mounts directly onto the rear cell of the StarSense Explorer 10” Dobsonian and works with any USB power source (portable power banks, AC wall adapters, and more). Once the primary mirror has cooled down and you are ready to observe, you can disconnect the fan’s USB power source. Connect the cable to the integrated storage clip to stay organized. Powering the Cooling Fan Any USB power source can charge the cooling fan. Unlike other fans on the market, this USB Cooling Fan for Dobsonian Telescopes does not require an external, bulky 12V power source or disposable batteries. This fan uses less voltage (5V vs. 12V) than competing models. Still, our rigorous internal testing shows that the Celestron Cooling Fan provides better airflow and faster overall cooling compared to competitors. Compatible Telescopes The USB Cooling Fan for Dobsonian Telescopes is compatible with the StarSense Explorer 10” Dobsonian telescope and many other third-party Dobsonians and Newtonian Reflectors that have a compatible fan mount (four M4 x 0.7 threaded holes in a square pattern with holes spaced 71.5mm apart). Review: Works for Apertura AD8! - I own a Zhumell Z8 which is the same as the Apertura AD8. This fan is nice because it runs on USB power instead of AA batteries, so you can use a rechargeable power source. When it arrived, I was a little worried because the included screws won't mount this fan to the mirror cell of an Apertura AD8 or Zhumell Z8 (they work on the Celestron telescope though). Do not worry! I used the screws that came with my original fan instead, and they fit. You do therefore need to remove the mirror in order to do this install, but it's not hard, and it's totally worth the trouble. I also recommend getting a USB extension cable because the cord attached to this fan is only a few inches long. Review: Designed for dobsonian telescope - Works great on my skyquest 10" dob. Just need a battery pack to run it and long usb cable (other items purchased here on desertcart!). Easy to mount too. But again you will most likely need a long usb and a power source. ## Features - USB-operated cooling fan for StarSense Explorer 10” Dobsonian and other Dobs and reflectors with a compatible fan mount - Speeds up the cooling of the primary mirror to the ambient air temperature resulting in crisper, better-focused views in less time - Mounts directly to the rear cell of the StarSense Explorer 10” Dobsonian telescope - Integrated storage clip to secure the USB cable when not in use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B7CTLFRR | | Best Sellers Rank | #526 in USB Fans | | Brand | Celestron | | Brand Name | Celestron | | Compatible Devices | Dobsonian Telescopes, Newtonian Reflectors | | Cooling Method | Air | | Customer Reviews | 4.5 out of 5 stars 29 Reviews | | Global Trade Identification Number | 00050234942560 | | Included Components | Fan | | Item Dimensions L x W x H | 3.74"L x 0.98"W x 4.72"H | | Item Highlight | Faster Mirror Cooling, Spend More Time Observing, USB Powered, Reduces Thermal Distortion, Quiet Operation, Easy to Install | | Item Weight | 0.11 kg | | Manufacturer | Celestron | | Material Type | Plastic | | Model | 94256 | | Noise Level | 30 db | | Number of Items | 1 | | Part Number | Black | | Power Connector Type | USB | | Product Dimensions | 3.74"L x 0.98"W x 4.72"H | | UPC | 050234942560 | | Unit Count | 1 Count | | Voltage | 12 volts | | Warranty Description | 2-YEAR WARRANTY | ## Images ![Celestron USB Cooling Fan for StarSense Explorer Dobsonian Telescopes - Image 1](https://m.media-amazon.com/images/I/61tgsnug2NL.jpg) ![Celestron USB Cooling Fan for StarSense Explorer Dobsonian Telescopes - Image 2](https://m.media-amazon.com/images/I/617BUn3KK-L.jpg) ![Celestron USB Cooling Fan for StarSense Explorer Dobsonian Telescopes - Image 3](https://m.media-amazon.com/images/I/71Rs3IQ32xL.jpg) ![Celestron USB Cooling Fan for StarSense Explorer Dobsonian Telescopes - Image 4](https://m.media-amazon.com/images/I/71qbZ+f1lAL.jpg) ![Celestron USB Cooling Fan for StarSense Explorer Dobsonian Telescopes - Image 5](https://m.media-amazon.com/images/I/61sJjeDz3bL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works for Apertura AD8! *by C***N on June 12, 2026* I own a Zhumell Z8 which is the same as the Apertura AD8.

Just need a battery pack to run it and long usb cable (other items purchased here on Amazon!). Easy to mount too. But again you will most likely need a long usb and a power source. ### ⭐⭐⭐⭐⭐ Works perfectly but install carefully *by M***Y on May 9, 2025* It works just fine, seems well built, looks nice, and fit my Celestron 12" Dob perfectly. BUT PLEASE NOTE: when you attach the fan to your scope, be sure the fan grill is correctly oriented. There is a bit of a bow in the grill, and that should be facing outward, away from the fan blade. I installed the gril with the bow facing inward (I did not realize there was a bow) and when I tried to activate the fan, nothing happened. After removing the fan from my scope and ascertaining that it was working properly, I looked more closely at the gril and realized that the grill has that bow, and if the bow if facing inward, it blocks the fan from rotating. Once I got properly installed, the fan works just fine. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/494807624-celestron-usb-cooling-fan-for-starsense-explorer-dobsonian-telescopes](https://www.desertcart.dk/products/494807624-celestron-usb-cooling-fan-for-starsense-explorer-dobsonian-telescopes) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-10-04*
