Telescope and Aperture

As humans we have lots of physical limitations which don’t affect our daily activity but sure can be used to improve your life. Human vision is one of the most important functions to let you perceive objects and used to create complex information in the brain which decides what our body has to respond to. As amazing as it is, they are not functioning as a super viewing organ that can let you see anything further than 3 miles away.

This is why we created devices that can assist the vision and help us see further for various purposes. One of the most common applications of zooming devices is to observe the celestial objects that are present outside of our atmosphere. This device is called a telescope which we are sure most people are familiar already with the term but, when it comes to application, unless those who are interested in astronomy, we don’t think it is something that is present in just any house.

Telescope is an amazing device as it lets you see objects that are located far away from our planet and probably not going to be explored yet in near future. It gives you an opportunity to see and observe the objects, to study, or just to take pictures and admire. Enthusiast usually have their own preference when it comes to telescopes; some may like the convenience of refractor and some may prefer the accuracy of reflector or some may like alt-azimuth while the rest like EQ better.

No matter which telescope fits in your application the most, their primary feature is aperture itself and the general rule is the bigger it is the more light they can gather hence, make the image sharper as well. Aperture plays the important role of generating light and as it is increasingly bigger, for example a telescope that doubles the initial size, the light collected increases by a factor of four such as 6-inch scopes will gather twice light than a 4-inch type.

Not only about a brighter and cleaner image, what’s great about larger apertures is that sharper images can be magnified more to let you peek into the finer details compared to those with poorer image quality; it is very similar to image by camera. In addition, not only fainter objects, larger and closer objects like moons and planets can be viewed in greater detail so you can see its surface better as those with larger apertures allow for higher magnification.

About Celestron Edge HD 8 and 9.25

The best part is always image quality but bigger aperture comes with a cost of giant tubes as well which limits their mobility and convenience especially if you are living in an apartment or have no backyard and storage room to keep the unit. At the end it is always best to balance the unit and your needs so then we can find the middle line that benefits you the most. For telescopes, the options are abundant and you can pick from any reliable brands out there.

We recommend shopping from those main products are telescopes because they tend to be more reliable and have better product’s quality compared to general brands. Talking about telescopes, one of the main players in the market is Celestron and we are sure you also agree that they are also among the best options for different ranges of telescopes from beginner to those with more experiences. Our favorite part from this brand is actually the vast options to choose from so everyone can have their best model.

If you are here then a versatile telescope is what you look for and instead of a refractor or reflector, SCT is probably the best for almost any applications. For this type, Celestron Edge HD 8 and 9.25 will be two great models to consider. Both of them are from the same line so it is not a surprise anymore that you can find the same things on either of them but, being different in aperture may also affect their performance as well.

Schmidt-Cassegrains are very popular nowadays from beginners to those who are more experienced and one of the best applications of the model is for photography. These types however, tend to be more expensive as well so if you want to optimize the budget and use the unit for observation only, a dobsonian will give you huge aperture at the same price compared to SCT. Overall we do think Celestron Edge HD 8 and 9.25 are amazing options due to their versatility and coming from Celestron, they are also very reliable in quality.

Celestron Edge HD 8 and 9.25 Design

As two close brothers these telescopes are very much identical to each other and in a glance probably very difficult to set apart. The bigger one is the 9.25 model and it is both larger in diameter as well as length because both are keeping the same focal ratio. They are made with the same level of quality and similar to most Celestron telescopes, the optical tube itself is made from aluminum measured at 9.37-inch by 17-inch compared to 10.7-inch by 22-inch.

Depending on which package you buy, for these two variants today they are only coming in optical tube assembly so you have to own or buy both tripod and their mounting or other required accessories to make the whole setup. However, for the main optics, you will get an eyepiece as well to get started quickly yet, we highly recommend to add more including barlow too for the best experience across their zooming range.

Celestron Edge HD 8 and 9.25 Specification

Moving further, let’s see what both Celestron Edge HD 8 and 9.25 can offer and as you can already guess, they are 8-inch and 9.25-inch aperture telescopes or 203.2mm compared to the 234.9mm model. They also have different focal lengths of 2032mm and 2350mm but the focal ratio is kept the same at f/10. For these models you will get one eyepiece in the box but differently, its little brother has the 40mm or the 51x magnification while the big brother has the smaller one at 23mm with higher magnification at 102x.

Being larger in aperture allows Edge HD 9.25 to be able to use smaller eyepiece with greater magnification and if desired, you can always have different eyepiece or barlow to add into the collection. They have the same 1.25-inch star diagonal in which the latter is achieved with an adapter while for the maximum usable zoom are 480x compared to 555x times.

Celestron Edge HD 8 and 9.25 Performance 

The most important part of any products including a telescope is their performance and both Celestron Edge HD 8 and 9.25 are amazing because they work just as advertised. In clear night these telescopes are performing wonderfully and their aperture itself are very ideal for astrophotography because they can capture quite lots of light. In comparison however, you will see slightly crisper images in Edge HD 9.25 especially if using a high magnification eyepiece while with larger eyepiece both are delivering the same image.

We do think in clear night or in a spot where there is no light pollution you can see a lot from these telescopes. For example Horsehead Nebula are looking very bright and amazing from any of them even with the eyepiece they carry in the box. Planet observation is great as well so for example moon craters and its texture are all very apparent from your scope but increasing the magnification you may see better image quality from the HD 9.25.

Celestron Edge HD 8 and 9.25 Mounting

The last part we want to mention is their mounting because it is necessary to find the one that matches Celestron Edge HD 8 and 9.25 dovetail. Celestron sold the suitable mounting for their optical tubes and for these two we can use their CGE saddle mounts so if you already have CGE Pro line or CGEM models then we can use them for these models as well. CGE mount itself is available in various models to let you choose which of them will match the application best.

These SCT telescopes are among the best when it comes to versatility because they are good for just planet observation, deep-sky observation, or for astrophotography as well as ideal for beginner or casual users with the hobby. In comparison their images look crisp and actually very much the same in lower magnification while the difference started to become apparent in higher zooms as Edge HD 9.25 will offer better image quality.

- Includes dovetail rail compatible with CG5 mount
- Aluminum Optical Tube
- Celestron's premium StarBright XLT coatings
- 2032 mm focal length (f/10)

Conclusion

All in all you can choose any of them as they are equally good and there is no bad option as well between the two. Personally we are satisfied with the Edge HD 8 inch type as it is offering sufficient clarity but also cheaper to save some.
