Celestron StarSense Overview

Connect the StarSense Autoguider V2 to your motorized Celestron alt-AZ or equatorial mount for easy telescope alignment and more precise go-to tracking. Upgraded from the earlier model with a screw-on dew shield, the autoguider aligns your scope in minutes with the press of a button and improves the accuracy of your mount's go-to function to greatly enhance long-exposure images. It will also walk you through a complete polar alignment in as little as five minutes. Equipped with a 4-element optical system, a Sony CMOS monochrome image sensor, and an onboard computer with free software and firmware updates, the StarSense Autoguider V2 can be operated with a NexStar+ hand controller and the SkyPortal app on your smartphone or with Celestron's CPWI computer software.

Quick Automatic Alignment
The StarSense Autoguider aligns your telescope to the night sky in about three minutes with the press of a button. It "sees" star patterns overhead and matches them to its internal database to automatically orient the telescope, so you can spend more time observing and imaging.
Improved Pointing Accuracy
Instead of simply placing celestial objects within the telescope's field of view, the Autoguider places them in the center of the field, even if you're using a high-powered eyepiece or today's small imaging sensors.
Precise Tracking
The Sony IMX462LLR-C monochrome, back-illuminated sensor ensures your targets are crisp and detailed, while background stars look like sharp pinpoints, never oblong or streaky.
Simplified Polar Alignment
The autoguider dramatically simplifies the polar alignment process. Simply follow the on-screen instructions on the hand control or in the CPWI software, and complete a full polar alignment in less than five minutes.
4-Element Design & Sony CMOS Sensor
The StarSense Autoguider features a high-quality 4-element optical design devised by the famed optical designer Mark Ackermann. The optical tube is threaded to accept 2" astronomical filters. Add an IR-pass filter to align your mount in twilight or a neutral density filter for daytime focusing. The device also includes an onboard computer and a highly sensitive Sony IMX290-DLL monochrome CMOS image sensor, all working together to provide exceptional guiding accuracy. You can view a live image from the camera via your PC if desired.
Advanced Options
Advanced users can fine-tune their autoguiding setup via CPWI's advanced settings. You can enable dithering options to move the mount slightly between camera sub-exposures, which may help your image processing software perform at its best. You can also guide on a comet via CPWI, simply select the comet from the software's regularly updated database of more than 100,000 celestial objects. Your purchase grants you access to all subsequent software and firmware updates.
Works with Your Current Setup
Choose how you want to control your StarSense Autoguider. It works with your NexStar+ hand control, CPWI telescope control software via a wired PC connection, or Wi-Fi (with a Wi-Fi-enabled mount or the SkyPortal Wi-Fi Module accessory). The autoguider also works with the rest of your Celestron accessories for a seamless solution that fits in perfectly with your telescope setup.

Celestron StarSense Reviews

Better than the Original

By Steven

I was blown away with the extended guiding I got with my Celestron Origin telescope. It's amazing, and it's pretty much plug in play regardless of what scope and EQ mount you're using. Five minute sub exposures blows my mind.

Works Great
