Should I just start flexing my Greek mythology knowledge instead of giving you guys the Athlon Cronus 20-60×86 review? Nah, I will do the review this time. Let me know if you guys want a story time or not. 

Coming back to the topic. The spotting scope we have here is from none other than Athlon. Athlon Optics is one of the most known optics manufacturers in the world. They are known for their clear vision and high-quality constructions. Let’s see if that’s true in Cronus’s case.

Build Quality

Cronus is not cheap. It’s not the most expensive scope on the market either. To grab attention, Athlon had to give their best behind this. 

Athlon went for magnesium chassis with this. Magnesium is a composite made out of magnesium and alloy. The result of the combination is a durable composite that is good for almost anything. 

Technically speaking, this scope is indestructible. I know in your head you already destroyed it by running over the scope with a road roller. You and I both know the chances of happening that to you is almost zero. 

There is a rubber armor coating all over the magnesium chassis. It makes the scope more durable and easier to grab without gloves. If you want to get a scope for the rest of your life. Cronus is an excellent option for that. 

The construction of Cronus is completely waterproof. There is no O-ring sealing involved in the making of it. But it’s proven that Cronus is completely waterproof and can be submerged. 

Optics Quality

Athlon went all out in this department. Keep reading you will know what I am talking about. The lenses of Athlon Cronus is made out of ED glass. ED glass stands for extra-low dispersion. It’s a special category of glass that doesn’t require too much light to work with. 

ED glasses are best for low-light performance. They are excellent at that job. Not even HD glass can beat them at the low-light competition. 


You might be wondering, why is there a separate part for coatings. Doesn’t TargetChaser include them in the optics section? You are correct. Usually, I approach the review from that angle. But with Cronus, I had to adjust my writing style. The reason is, Cronus comes with a lot of coatings.

To start, the lenses of Cronus are advanced fully multi-coating. Advanced fully multi-coating gives you brighter and color-accurate images. 

The prism inside the Cronus is BaK4. BaK4 is known to reflect bright lights directly onto your eyes. That’s why the image clarity and color contrast are better on the BaK4 prism. Athlon coated the prism with ESP Dielectric Coating. It’s a multi-layer coating that makes the prism reflect 99% of the light directly on to your eyes. Making the image brighter and sharper.

Besides advanced fully multi-coating. The outside layer of lenses is XPL coated. It’s a special sort of coating to eliminate the risk of lenses getting scratched. In my opinion, even if it costs a bit of money. Every scope should start using this coating. It makes the scope so much better. 

To make all of these lenses fog proof. The inside of Athlon Cronus is argon purged. Argon eliminates any chances of moisture getting inside the scope and creating fogs inside. If you live in an area where it snows a lot. Don’t worry Cronus is an excellent option for you. 


The maximum magnification of this scope is 60x. The unusual part of the scope is the objective lens. Instead of the typical 60mm or 80mm objective lens. Athlon went for a 86mm objective lens.

With the sheer number of coatings and the excellent prism, at full magnification, you will have an experience that you will remember for the rest of your life. 

Athlon Cronus also has dual focus control. The focus controlling knobs are right above the rotating mounting plate. You can easily use two fingers to control both of the knobs. 

There is no distortion or lag while magnifying the scope. With dual focus mode, you can manually focus on different objects. Making it an ideal choice for birdwatching and digiscoping. 


For digiscoping, you will need to buy a digiscoping kit. Make sure to buy a good one to complement the scope. This scope will be an excellent choice for digiscoping. The image clarity and color accuracy make it one of the best digiscoper on the market. 


For birdwatching, I always prefer angled spotting scope. The eyepiece of this scope makes it an excellent buy for birdwatchers. The eye relief is generous. The size of the eyecup and eyepiece is quite big too. Bigger than a regular spotting scope or a binocular. You will have a lot of fun seeing through the eyepiece that’s for sure.

Athlon Cronus 20-60x86 Review Summary

Athlon Cronus may not be as powerful as the king Kronos. But it surely will hold a fair fight against him. As for spotting scope competition, Cronus can leave competitions in the dust.

I understand it’s an expensive investment. But you will make this investment for over a decade worth of use. In that sense, it’s an excellent investment in my book.

That’s it for today. The Athlon Cronus 20-60×86 review ends here. I hope you found this review helpful. If you didn’t then feel free to let me know why you didn’t find it helpful.
