Unistellar\u2019s new Odyssey Pro telescope offers access to deep-sky astrophotography in a small portable package.<\/em><\/p>\n Access to the night sky has never been simpler. The last half decade has seen a revolution in backyard astronomy, as \u2018smartscopes\u2019\u2014telescopes controlled by smartphone applications\u2014have come to the fore. These offer an easy entry into basic deep sky astrophotography even from bright urban skies, albeit at a higher price point versus traditional telescopes on the market. We\u2019ve reviewed units from Vaonis and Unistellar before, as well as wrote commentary on the rise of the whole smartscope movement. Now, Unistellar has a new entry on the market in 2024: the Odyssey Pro.<\/p>\n <\/p>\n The Odyssey Pro is lightweight, at 14.3-pounds (65 kilograms) assembled plus carbon fiber tripod. The telescope sets up quickly, with the tube and base securing to the top ring of the tripod.<\/p>\n The telescope at the heart of the system is an 85mm aperture reflector with an f\/3.9 320mm focal length. The image sensor (in place of where the secondary mirror would be on a traditional telescope) is a 4.2 megapixel camera. The turret on the side of the tube houses an electronic eyepiece incorporating Nikon\u2019s Eyepiece Technology, providing an enhanced view. The addition of the eyepiece turret is the key difference between the Odyssey and Odyssey Pro.<\/p>\n Smartscopes find and aim at targets using a method known as \u2018plate-solving\u2019 in tandem with satellite GPS. This involves looking at segments of the sky, and comparing the star pattern with a known database. You can see this in action as the scope slews from one part of the sky to the next on startup. Unlike, Vaonis\u2019s Stellina, Unistellar\u2019s telescopes give you a live view during the slewing process, and allow users to manually slew around the sky in a virtual joy stick mode, a nice, hands-on touch.<\/p>\n The new app interface for Unistellar is updated as well\u2026 I was surprised to actually find all of my old eVscope images in the cloud memory, from years back. The unit is USB-C charged, and offers about five hours of use in the field. The Odyssey Pro has 64Gb (gigabytes) of internal storage memory.<\/p>\n The company offers a free backpack with each purchase. The Odyssey Pro runs for $3,999 USD, and the company frequently offers discount sales.<\/p>\n The Odyssey Pro is smaller (85mm aperture, versus 112mm) than the eVscope, but similar in operation. The Odyssey features auto focus technology: no more Bahtinov mask manual focusing like with the eVscope. We also got to try out the smart solar filter for the unit. The filter clicks magnetically in place of the front of the telescope. I\u2019d keep a close eye on the unit when using it this way during public observing, as curious hands could easily snag or pull the filter off during observation. While there\u2019s no danger of blinding a viewer, a few seconds of unfiltered Sun could easily damage the telescope. The unit easily found and slewed to the Sun, then focused and color corrected the image. <\/p>\n What we like- Like the Unistellar eVScope, the Odyssey Pro just works as advertised: set it down, power it up, and you\u2019re slewing to targets within minutes.<\/p>\n What we don\u2019t like-The newer app seems a bit \u2018balky,\u2019 and I needed a cold boot the telescope during a few sessions to get things up and running again\u2026 also, it seems very sensitive to any vibration during enhanced imaging mode, even on solid concrete. <\/p>\n The telescope will wifi bond with the app in the field without a dedicated internet connection. This is a must for using it at a remote spot. <\/p>\n But the real magic happens when you engage the enhanced vision mode. This initiates a process where the scope starts to stare at a target, stacking and cleaning up the image. The longer it runs, the brighter and sharper the image gets. Unistellar\u2019s new method is known as \u2018Vivid Vision\u2019 and compares and refines images versus the user database to validate what the telescope is seeing. Color correction for stars and validation also uses Gaia\u2019s latest DR3 catalog.<\/p>\n Our first night out with the Odyssey Pro saw us showing off about a dozen deep sky objects to a small group under the bright lights of downtown Bristol, Tennessee. Ironically, while you can view the Moon and planets with the Odyssey Pro, its relatively wide (33.6 x 45\u2019, a little larger than a Full Moon) field of view really shines when viewing deep-sky nebulae and clusters.<\/p>\n Are smartscopes worth the price? I\u2019d say the Odyssey Pro (or any smartscope) has three key advantages:<\/p>\n -Finding objects: the whole plate-solving slewing method really puts me out of a job\u2026 and that\u2019s probably a good thing. Rather than spending time star-hopping and studying star charts to find an object, the Odyssey Pro simply goes there and centers the target in the field.<\/p>\n -Imaging from urban sites: The Odyssey Pro puts fainter objects in reach of urban viewers.<\/p>\n -Use for public outreach: At a star party, folks can gather around and watch as the view emerges. No more queuing up to the eyepiece, refocusing for every user, or explaining how to look through a telescope. I can spend more time talking about space and what<\/em> we\u2019re seeing, rather than fussing with gear.<\/p>\nSpecifications for the Odyssey Pro <\/h2>\n
