Should you buy Celestron AstroMaster 90mm Telescope to observe galaxies?
The Celestron AstroMaster 90mm Telescope is not recommended for observing galaxies. Its slow f/11.1 focal ratio and narrow field-of-view make viewing large, diffuse objects challenging. The 90mm aperture limits light-gathering ability, with a stellar magnitude of 12.5 insufficient for revealing faint galaxy details. The substandard manual mount lacks precise tracking capabilities needed for effective galaxy observation. Galaxies appear small, faint, or not visible at all through this telescope. The AstroMaster 90mm is better suited for observing the moon and planets. We advise considering a telescope with a larger aperture, faster focal ratio, and more robust mount for improved galaxy viewing.
Should you buy Celestron AstroMaster 90 Telescope for astrophotography?
The Celestron AstroMaster 90 Telescope is not recommended for astrophotography. Its substandard mount lacks motors and GoTo controls, making celestial object tracking difficult. The plastic focuser and diagonal mirror introduce reflections, degrading image quality. The mount’s instability causes vibrations and blurred images. The telescope excels at nighttime viewing of planets, moon, and star clusters. It provides bright and clear images for visual observation. The 90mm aperture and 1000mm focal length suit planetary and lunar viewing. The telescope’s easy setup appeals to beginners and casual astronomers exploring the night sky on a budget. Astrophotography enthusiasts should choose telescopes with sturdier mounts and better optics specifically designed for imaging.

My experience with the Celestron 90mm AstroMaster refractor telescope has been a wild ride. The AstroMaster 90 telescope by Celestron initially blew me away with crystal-clear views of the moon and planets. Images were bright and steady, allowing observation of amazing details. Substandard features became noticeable with more use. The flimsy tripod caught my attention first. Securing the tripod is challenging, requiring creative solutions with weights and counterbalances. Observing sessions are limited to shorter periods due to this issue. The telescope itself provides a different experience.

The Celestron 90mm AstroMaster refractor telescope has exceeded my expectations. Astromaster 90 telescope by Celestron delivers clear and bright images of the night sky. Nighttime viewing has been a treat for me. Stars and planets appear up close through the eyepiece. Pretty easy to set up and use for a beginner like me. Adjustable tripod is sturdy and allows smooth movement for tracking objects. Great sized telescope for users like me. Celestron has delivered a high-quality product. Primary mirror provides surprisingly good performance. Embarrassingly obvious that the telescope isn’t permanently attached to the tripod. Users should be careful not to knock it over.

Stars appear steady, and I saw the moon’s craters in great detail. The stainless steel tripod is sturdy and easy to set up – a big plus for hassle-free viewing. Focuser starts stiff but becomes easy to use with practice. My only complaint is the substandard finder scope, which has a slightly distorted image.
Berfin (verified owner) –
The Celestron 90mm AstroMaster Reflector Telescope felt light at first, which seemed like a plus. Astromaster 90 Celestron Telescope’s light weight turned out to be a sign of substandard build quality. Materials feel cheap and flimsy. Instructions were woefully inadequate, making setup a quick but frustrating process. Images weren’t perfect, with low light performance being particularly poor. Major letdown considering the brand’s reputation for higher quality. Solar system and terrestrial views have the same issues – image quality just isn’t up to par. Multiple attempts yielded consistently underwhelming results.

Nicholas Wiggins (verified owner) –
It’s a big step up from my old one, delivering accurate views of the night sky. The erect image optics make observation easy – no inverted images to worry about. On clear nights, I spotted a large nebula in deep space with remarkable clarity. The telescope’s ability to resolve fine details is much better than expected. The tripod is substandard though, not very sturdy and prone to vibrations. Despite only having it for a short while, I’m certain it will provide many hours of stargazing enjoyment.
