Celestron Wedge Review [Longer Exposure Astrophotography]

If you are considering the Celestron Wedge then this review and guide will help you decide whether or not you should get it for your Celestron NexStar 6/8SE or NexStar Evolution Alt-Azimuth mounted computerized telescope.

Here, we will take a look at the specification, what it will enable you to do, and the main pros and cons behind using it.

Celestron Wedge Review

Celestron Wedge

Weight: 15 lbs

Latitude Range: 0°-70°

Additional Items: 5 hex keys for assembly, Instruction manual

Celestron Wedge Performance

I purchased and use the Celestron Wedge on my Celestron NexStar 6SE.

It’s a very solid, sturdy wedge with allows me to now follow objects with no Field of Rotation which is my primary reason for purchasing it, to begin with.

Without the wedge, I was typically getting only about 5-10 second exposures before I started to see star trails.

Now, with this wedge, I am experiencing 5 minute + exposures. I should be able to improve this further once I upgrade my camera.

When the wedge was first delivered one of my initial concerns was setting it up and configuring it – the Instruction Manual and PDF helped greatly with this.

The altitude adjuster was installed easily but it did take me some time with the Azimuth Knob.

One of the main concerns from other users of the Celestron Wedge is that there is not enough space around the Collar and that the mounting bolts provided are too long affecting the motor and ability to pivot.

When the bolts are tightened, this ensures the handle remains close to the inside edge of the wedge enabling the Block assembly to move freely backward and forward.

While other users resort to filing the bolts to enable rotation, I simply removed the e-ring on each bolt and added a washer near the knob to shorten the bolts and this solved the issue. I’d suggest you do the same.

When it comes to actually use the Wedge, the entire align process is very easy, altitude adjustments work brilliantly and the Azimuth knob works freely with the adjustments to the bolts.

Celestron Wedge with NexStar Evolution/SE, Black (93665)
  • Equatorial wedge for Celestron NexStar 6/8SE and Evolution Alt-Az mounted computerized telescopes
  • Enables long exposure astrophotography and autoguiding by tilting the telescope’s azimuth into an equatorial platform allowing it to track an arc around the polar axis
  • For beginner to intermediate planetary and deep space imagers
  • Captive hardware, tool-less operation, easily adjusts under load
  • All new hefty yet portable design

Bottom Line 

The Celestron Wedge is required to take longer exposure images or to advance further and use an auto guider.

Personally, I’ve managed to up my exposures from around 10 seconds to 5 minutes.

It combines premium Celestron technology keeping it light and portable yet sturdy and offering extra support.

And it does this at an affordable price point (best price on Amazon). With the Wedge, you’ll be able to take long-exposure Astrophotos because it will allow your mount to track equatorially, and eliminate any field rotation.

When you consider its applications, light yet stable frame, you’re not going to find many better wedges for your Celestron 6SE/8SE/Evolution than this.

Pros Of The Celestron Wedge

✔️ Ideal for any telescope in the Celestron NexStar and Celestron Evolution Telescope Range.

✔️ Increased Exposures from 5-10 seconds to 5 minutes+.

✔️ Enables long exposure astrophotography and auto guiding by tilting the telescope’s azimuth into an equatorial platform allowing it to track an arc around the polar axis.

✔️ Premium design; the anodized parts add a nice touch of color so it perfectly matches your telescope,

✔️ Solid and effective Altitude Knob

✔️ Upgrade kit provides 3 threaded adapters that fit on top of the factory holes on the tripod. These adapters elevate the wedge slightly, allowing you to move the Azimuth while the wedge is tightened down.

✔️ Solid and Sturdy yet relatively Lightweight; portable and easy to carry.

✔️ For beginner to intermediate planetary and deep space imagers,

✔️ Captive hardware, tool-less operation, easily adjusts under load,

✔️ Sturdy latitude adjustment screw with easy-to-read scale and integrated Bubble level.

Cons Of The Celestron Wedge

❌ Difficult to assemble for the first time so takes a bit of getting used to. There’s an Instruction Manual included in the box and an additional PDF you can download from the Celestron Website to help.

❌ The two mounting bolts that hold the mounting fork are about 3/16ths of an inch too long affecting the motor and the ability to pivot. Removing the e-ring on each and adding a washer near the knob to shorten the bolt, solves this issue.

❌ Upgrade kit is not pre-installed but instead is considered optional. You will likely need to use it.

Telescope Wedge Buyers Guide

Let us now look at some of those questions you may have on this particular product, or surrounding wedges in general.

What Is A Telescope Wedge?

A telescope wedge or equatorial wedge is a component that you can place between your fork-mounted telescope and its tripod.

This will adapt your Alt-Azimuth mount and turn it into an equatorial mount.

Telescope wedges are set to a specific latitude range, the Celestron Wedge being 0-70° so you will need to be aware of your location beforehand.

The main benefit of an equatorial mount (whether a fork on a wedge, a GEM, or any other design) is that you can track objects across the sky with a single motor and, more importantly, with no field rotation.

Field of Rotation is the spin of objects in your telescope relative to the orientation of the location of your telescope and where you are observing from.

Over a long exposure, for example, 5 hours… an object (e.g. a Nebula) will be pointing in a completely different direction.

So with no Field of Rotation, you’ll be tracking the object in perfect alignment for the entire 5 hours. It will not move.

This makes it an ideal instrument if you’re into, or want to get into Astrophotography.

Features Of Good Telescope Wedge

If you are considering the Celestron Wedge, then it’s good to know some of the best features to look out for:

Load Capacity:

The Load capacity simply refers to the weight that the wedge can take without performance being affected.

It’s actually a very important aspect to consider because if your wedge cannot support the telescope you intend on using, you risk damaging your telescope and you’ll also have purchased a wedge that you can no longer use.

In the case of the Celestron Wedge, it has a load capacity of 36 lbs which is a considerable amount of weight.

This, therefore, provides a solid base for your 6SE/8SE or Celestron Evolution.

Construction And Design

Following on from Load Capacity, you want your wedge to be solidly constructed and intuitively designed.

This makes it durable, a lot easier to install, and far more effective to use.

The Celestron Wedge is a well-built, very solid wedge. The anodized parts add a nice touch of color and make it look aesthetically pleasing.

You will just need to ensure you tighten down everything after polar alignment has been achieved.

Weight and Portability

The relative size and weight of a wedge affect its overall portability. This wedge, despite being very solid and sturdy is only 15 lbs.

This is not overly heavy ensuring you will be able to take it with you on the go.

Final Verdict

This is one of the best wedges on the market for the price point.

If you want to pursue astroimaging and have 6/8SE or Evolution, then this is in my opinion a must-buy.

With its sturdiness, ease of use, portability, and sleek design this is a brilliant wedge to get.

  1. Hello, finally I got a very good explanation about the wedge for the Nexstar series telescopes. I have a Nexstar 8se and my question is if the azimutal arm will be damaged over time because of the weight of the scope when this one is tilted. Some reviews online have stated that isue and really concern me about ruining my telescope. Thanks in advance for any comments on this.
