Radian Raptor 61 f/4.5 Imaging APO Telescope
Here at Radian Telescopes, we believe in building gear that works seamlessly with any system, so you can focus on doing what you love — capturing awe-inspiring images of the cosmos — instead of wasting hours fussing with adapters, mounting, and other headaches. That's why we built the Raptor 61: a portable, widefield 61mm f/4.5 apochromatic triplet refractor packed with features that any astrophotographer would want for turnkey imaging. Being astrophotographers ourselves, we know how frustrating it feels to have perfectly clear skies overhead but you waste the night trying to get your equipment to work the way it should. With the Raptor 61, wasted nights can be a thing of the past. With its wide field of view, the Raptor 61 is the ideal choice for producing stunning images of deep sky objects that cover wide swaths of the night sky.
Tack-Sharp, Fast OpticsWe know how agonizing it is to have to spend multiple nights capturing images when using a slow system. With its fast f/4.5 focal ratio, the Raptor 61 allows for shorter exposures, making it possible to capture quality data on multiple targets in a single night.
High-Quality GlassThe Raptor 61 features an apochromatic triplet optical design with premium glass and multi-coatings to tackle chromatic aberration with ease, leading to an ultra-clean overall image without the nuisance of reflections.
Wide Field of ViewThe 275mm focal length is simultaneously excellent for widefield imaging and highly forgiving, making it the perfect choice for both beginners and experts. Targets like the entire Veil Nebula and the Orion & Horsehead Nebula together can fit easily into frame on up to full frame sensors.
Dedicated CorrectorWith the Raptor 61, there's no need to buy an additional reducer/flattener. The dedicated, factory-matched corrector that comes as standard is intended to be used as an always-on solution for imaging. The corrector's three-element design provides correction for sensors as large as full frame, so no matter which camera you use, pinpoint stars can be seen across the image.
Factory-Tuned FocuserYou shouldn't need the world's steadiest hands to nail the focus on your telescope. To bypass this, we chose an ultra-sturdy 2.5" dual-speed rack & pinion focuser for the Raptor 61 that's factory tuned to allow extreme levels of precision when focusing. The 10:1 gear ratio of the coarse and fine focus knobs makes nailing tack-sharp focus a breeze for anyone.
Upgradeable Automated FocusingFor those who want to do away with the task of manually focusing altogether, we are pleased to offer the optional USA-made Radian Electronic Focuser as an immediate automation upgrade. We know some prefer not having to second-guess focus accuracy by hand, or would rather control their system from inside on colder nights. The Radian Electronic Focuser's high-resolution stepper motor allows you to adjust focus directly (without an additional focus controller) via software from your computer to ensure you get perfect focus automatically every time.
Integrated Filter VaultAdding filters to imaging rigs can make figuring out the correct backfocus challenging. The Filter Vault is integrated directly into the Raptor's included adapters, so you can easily swap out your favorite 2" filters and never worry about spacing or backfocus. Unlike most other telescopes which require an additional filter drawer for an added cost, the Raptor 61 has you covered out of the box.
Innovative Ring DesignWith a design that hasn't changed in over a century, traditional tube rings can cause you to lose precious hours of imaging time when a cable snags on one of the tightening screws. On top of that, many have wasted time trying to figure out how to attach additional accessories like a guide scope, power box, or other add-ons. To end these issues once and for all, we designed a brand new, innovative set of rings just for the Raptor 61: the Radian Modular Hex Rings.
No More SnagsThe Modular Hex Rings feature a six-sided construction with mounting holes on all sides to attach any accessory you need, saving you headaches and trips to the hardware store. Cables can be routed through integrated cable channels in the rings for improved cable management. Unlike tightening screws that protrude off of the scope and get caught easily, the Modular Hex Rings have a quick-clamp design that eliminates the possibility of cable snags.
Two Dovetails IncludedWe know what it's like to buy a telescope and be ultra excited to receive it, only to find that the dovetail that came with the scope doesn't fit onto your existing mount. For that reason, we decided that the Raptor 61 should come standard with both a 6.5" universal Losmandy D-style dovetail and a 4" Vixen V-style dovetail. Having both at your disposal means you can start using your new Raptor 61 right away on any variety of mounts you already own.
LightweightForget having to haul your heavy equatorial mount far from home. At a total weight of just 4 lbs (1.8 kg), the Raptor 61 can be carried on even the lightest travel mounts, including star trackers like the Sky-Watcher Star Adventurer Pro or the iOptron Skyguider Pro, with weight to spare for a camera as well.
Defend from DewIncluded dew shield helps fend off dew from forming on the objective on humid nights, and front and rear dust covers protect the telescope's optics when not in use.
Rotating Made EasyRotating the camera to get the ideal framing has never been simple with many telescopes. On the Raptor 61, we chose a built-in 360º rotator that makes it easy to frame your images to your ideal composition without having to rotate the entire telescope.
Simple Camera AttachmentSome telescope manufacturers use proprietary thread sizes on the back, making it difficult to find the right adapters to attach your camera. We chose a simple, industry-standard M48 thread size with full frame sensors in mind for this very reason. Simply attach an M48 wide T-ring with any DSLR or Mirrorless camera and you're ready to image. The threads can also easily be sized down to smaller formats, such as M42, using the adapters that most manufacturers supply with dedicated astronomy cameras.
Say goodbye to pricey custom cases and plucking foam when trying to transport your telescope. The Raptor 61 comes standard with a Radian travel backpack complete with padded inserts sized for carrying the telescope, a CMOS camera, and a number of other accessories safely when you head out to your favorite dark sky site.

This scope is a part of my 10 mm incremental collection of scopes - from 40 mm to 152 mm I eagerly await it for use and enjoy the difference Trevor’s videos have helped me a lot - this purchase is my way to say thank you to him and to enjoy the sky through his lens ... Keep up the great work Trevor...
This will be my first telescope of this kind. I can not wait to see what images I can get.
Saving up for this scope!!! CONGRATS TREVOR!!!!
Just ordered it. Can’t wait!! Way to go Trevor!!!
