The catch
Celestron Nature DX 8x42
Lower magnification for distant detail
Side by side
Celestron Nature DX 8x42 vs Celestron Nature DX ED 10x42 Compared: ED gives more magnification, and the shared 6.5-foot near limit stays where it was
Quick verdict
Moving garden birds, lower carrying weight and the longer eye-relief candidate point to the Nature DX 8x42. When distant detail matters more, choose the Nature DX ED 10x42. Focus starts at 6.5 ft on both, so a nearby feeder does not call for the ED upgrade.
Before you buy
Why, and what it costs you
The standard DX handles the same close feeder
A 7 ft feeder setup is within range for both. ED glass is a material specification, so don’t mistake it for an improvement in minimum focus distance.
Where this comes from
Close focus is listed at 6.5 ft for both exact models, along with eye-spacing adjustment of 56–74 mm.
The catch
Celestron Nature DX ED 10x42
Eye relief is shorter at 14.3 mm
Celestron Nature DX 8x42
- Why pick it
- Your glasses stay on while you follow birds
- Saving 2.7 oz matters on your walking route
- The catch
- Lower magnification for distant detail
Celestron Nature DX ED 10x42
- Why pick it
- You are buying mainly for detail on distant, stationary subjects
- 10x magnification is worth the shorter 14.3 mm eye relief to you
- The catch
- Eye relief is shorter at 14.3 mm

What this page compares
Celestron Nature DX 8x42 vs Nature DX ED 10x42. A 7 ft feeder is within reach of both. The 8x is lighter with the wider view, and the 10x gives up eye relief to gain magnification.
A practical 8x garden choice set against a higher-power ED model, with no pretense that ED glass alone predicts a measured image-quality winner.

In practice
Differences you will notice
The standard DX handles the same close feeder
A 7 ft feeder setup is within range for both. ED glass is a material specification, so don’t mistake it for an improvement in minimum focus distance.
How we worked this out
Close focus is listed at 6.5 ft for both exact models, along with eye-spacing adjustment of 56–74 mm.
The 8x geometry suits walks with moving birds
With the Nature DX 8x42 you get 25.6% more field width and 2.7 oz less to carry. Those changes bear on the routine more directly than a glass label does.
How we worked this out
The fields measure 388 and 309 ft, making the 8x field wider by 79/309, or 25.6%. The weights are 22.2 and 24.9 oz.
If glasses stay on, look hard at the upgrade
The 10x ED model magnifies 25% more but has 3.2 mm less eye relief. A personal fit failure can outweigh the appeal of a larger image of a distant subject.
How we worked this out
The magnifications are 8x and 10x, and the eye relief figures are 17.5 and 14.3 mm. There’s no matched sharpness or transmission testing available here.
Option A
Celestron, Nature DX 8x42
Nature DX 8x42
General outdoor viewing is covered by the 388 ft field and 22.2 oz weight. If it will be shared, check the 56–74 mm eye-spacing range against every person who will use it.
- Best for
- Your glasses stay on while you follow birds
Facts we checked
- Magnification: 8x
- Scene width: 388 ft at 1,000 yd

Option B
Celestron, Nature DX ED 10x42
Nature DX ED 10x42
Near focus stays at 6.5 ft and weight at 24.9 oz, as on the 8x version. If you wear glasses, the 14.3 mm eye relief deserves a harder look.

Spec by spec
Where they really differ
| Spec | Celestron Nature DX 8x42 | Celestron Nature DX ED 10x42 | In practice |
|---|---|---|---|
| Magnification | 8x | 10x | Since the ED model here is 10x, this is a choice of power as well. |
| Scene width | 388 ft at 1,000 yd | 309 ft at 1,000 yd | The field is 25.6% wider on the 8x. |
| Eye relief | 17.5 mm | 14.3 mm | The 8x model gives 3.2 mm extra. |
| Weight | 22.2 oz | 24.9 oz | The ED 10x body is 2.7 oz heavier. |
| Closest focus | 6.5 ft | 6.5 ft | Near focus gets no upgrade. |
Trade-offs
What each pick costs you
With Celestron Nature DX 8x42
- A personal glasses check is still needed with 17.5 mm eye relief
With Celestron Nature DX ED 10x42
- The field is narrower and the body heavier
Change of plan
When the answer changes
You walk, track moving subjects and leave your glasses on
Go with Celestron Nature DX 8x42. A wider field, lower weight and longer eye relief all point to the same choice.
You look at distant stationary subjects, and the 10x suits you comfortably
Go with Celestron Nature DX ED 10x42. The reason to upgrade is the extra magnification.
Your feeder is just 6 ft away
Neither model fits. Both minimum focus distances are greater than 6 ft.
Decision guide
How to decide
The Nature DX 8x42 is the pick for moving garden birds, lower carrying weight and the longer eye-relief candidate. Go with the Nature DX ED 10x42 if distant detail is what matters more, keeping in mind that both focus from 6.5 ft and a nearby feeder does not require the ED upgrade.
The standard DX handles the same close feeder
A feeder 7 ft away works with either one. ED glass is a materials specification and says nothing about minimum focus distance, so do not read it as an improvement there. Each exact model lists 6.5 ft close focus and 56–74 mm eye-spacing adjustment.
The 8x geometry suits walks with moving birds
Field width is 25.6% greater on the Nature DX 8x42, and it carries 2.7 oz less. Those two changes shape your routine more directly than a glass label does. The fields are 388 and 309 ft, so the 8x field is wider by 79/309, or 25.6%. Weights are 22.2 and 24.9 oz.
If glasses stay on, look hard at the upgrade
The 10x ED model gives you 25% more magnification and 3.2 mm less eye relief. If it fails to fit you, that can outweigh the appeal of a bigger distant subject. Magnification is 8x and 10x, and eye relief is 17.5 and 14.3 mm. Matched sharpness or transmission testing is not available here.
What this page can’t tell you
- This all rests on manufacturer specifications and comparisons that can be reproduced. It involves no hands-on tests of sharpness, steadiness or brightness.
- Dividing objective diameter by magnification gives the exit pupil. That figure does not establish measured light transmission or a winner in low light.
- Neither published eye relief nor body dimensions guarantees a personal glasses fit or clearance inside a packed case.
