Should you buy SkyWatcher 900mm Refractor Telescope to observe planets?
Yes, you should buy the SkyWatcher 900mm Refractor Telescope to observe planets. The telescope’s 900mm focal length is ideal for producing high-quality, detailed images of celestial objects, planets. Refractor telescopes like the SkyWatcher 900mm excel at planet viewing due to their ability to produce sharp, high-contrast images with minimal chromatic aberration. The SkyWatcher 900mm outperforms large reflectors with poor optics for planet observation, allowing better discernment of planetary surface and atmosphere details. The telescope’s mount exhibits some weakness in tracking faint objects, but this limitation has less impact on planetary observation, which involves brighter targets.
Should you buy SkyWatcher 900mm f/10 Refractor Telescope to observe galaxies?
The SkyWatcher 900mm f/10 Refractor Telescope is not recommended for observing galaxies. Galaxies require telescopes with large apertures and wide fields of view to gather sufficient light and resolve faint details. The SkyWatcher 900mm has a small 90mm aperture and narrow field of view due to its f/10 ratio, making it inadequate for galaxy observation. Reflector telescopes with apertures of at least 150mm are preferred for galaxies. Reflectors gather more light and provide wider fields of view than refractors. High magnification is unnecessary for galaxies; light gathering capability is more important. The SkyWatcher 900mm excels at observing planets and the Moon but falls short for galaxies. Beginners on a budget have other options available that prioritize wider fields of view and better light gathering capabilities for effective galaxy observation.
Should you buy SkyWatcher 90mm Refractor Telescope for astrophotography?
The SkyWatcher 90mm Refractor Telescope is not recommended for serious astrophotography. Refractor telescopes are suitable for astrophotography, but this model has significant limitations. The equatorial mount is inadequate for stable tracking and long exposures. The narrow field of view restricts deep-sky imaging possibilities. The f/10 focal ratio (900mm focal length / 90mm aperture) makes wide-field shots challenging. Lunar and planetary imaging is possible due to the lightweight design and easy setup. Minimal maintenance is required as collimation is unnecessary. User reviews are mixed, with some reporting success in lunar and planetary imaging while others find results unsatisfactory. Upgrading the mount or adding accessories is costly and limited in availability. Budget considerations are important when evaluating this telescope for astrophotography purposes.
Is SkyWatcher 90mm f/10 Refractor Telescope portable?
The SkyWatcher 90mm f/10 Refractor Telescope is moderately portable. The telescope weighs 12kg and measures 120cm x 25cm x 25cm, making it manageable for easy transport. Users mount the telescope easily on its steel tripod, which stands 120cm tall with 50mm diameter legs. The equatorial mount and tripod allow for quick setup and free movement around the observing site. Astronomers transport the telescope to different locations without significant difficulty. The telescope balances portability with stability, suiting users who need occasional transport without requiring an extremely lightweight design.

The SkyWatcher 90mm telescope is lightweight and easy to transport. Setup of the SkyWatcher 3.5″ refractor telescope was quick and straightforward. Image quality disappointed me at first. Views appeared faint and hazy through the eyepiece. Research and tweaking settings improved things dramatically. The sky became crisp and clear with excellent contrast. Observing the entire moon’s surface revealed stunning detail.

The SkyWatcher 90mm refractor telescope delivers decent image quality after a few nights of use. SkyWatcher 3.5″ refractor telescope performs exceptionally well for observing faint objects like nebulae, producing bright and clear images. Humid nights can cause dew buildup, affecting image quality. A slight focuser adjustment usually resolves the dew issue.

Stargazing has been an interest of mine for a while. Used it for the first time with amazing results. Clarity and detail of the images blew me away. Lunar surface appeared with incredible precision. Spotted small craters I hadn’t noticed before. Equatorial mount stands out as a notable feature. Much easier to use than altazimuth mounts from my past experience. Tracking objects across the sky was a breeze. Slow-motion controls made fine adjustments simple. Setup takes a bit of time but is well worth it. Performance on deep-sky objects is impressive too. Orion Nebula showed up in stunning detail. Stars in the Pleiades cluster looked like diamonds against black space. Telescope can be a bit low to the ground. Might need a stool or chair for comfort while using it. SkyWatcher 3.5″ EQ refractor telescope is definitely worth the investment.

The SkyWatcher 90mm refractor telescope has exceeded my expectations in optical quality. Images from the SkyWatcher 900mm refractor telescope are crisp and clear. Specific details on the moon and planets are now visible, which I couldn’t see with my old scope. The manual was brief and lacking, but I figured out the setup without much trouble. Focuser can be slow to adjust, yet it’s not a major issue for me. SkyWatcher 90/900 is fine for my needs, providing great views of the night sky. I’ve been using my own eyepiece instead of the included one, making a big difference in image quality. Here’s a specific example: I saw Saturn’s rings clearly, which wasn’t possible with my old telescope.

I got the hang of setting up the SkyWatcher 3.5″ telescope after a few attempts. Instructions were detailed, but I had to check online forums for precise assembly tips. The telescope’s performance pleasantly surprised me. Views of the night sky are clear and sharp. Seeing the moon and planets is easy. The vertical stabilizer really impressed me, making object tracking smooth. Focuser is precise and allows for fine adjustments. Nearly flawless optics stood out, showing lots of detail in observed objects. Images barely had any chromatic aberration. I’ve only had the telescope for a few weeks. Amazing sights include a stunning view of the Orion Nebula.

The SkyWatcher 90mm refractor telescope delivers excellent image quality, providing crisp and clear views of celestial objects. SkyWatcher 3.5″ refractor telescope has exceeded my expectations for planetary viewing. The mount is stable and sturdy, allowing easy object tracking. Setup and takedown are a breeze. I’ve observed objects I never expected to see with a telescope this size. The telescope handles much more magnification than anticipated – I’ve pushed it to 200x without significant image quality loss. Planetary observations are where this telescope really shines.
Cody White (verified owner) –
As a first-time telescope owner, I’ve been stargazing for weeks now. Setup was a breeze with clear instructions. The moon looks stunning through it – craters and mountains stand out clearly. I opted for the 10mm optical eyepiece instead of the standard one. Planets appear amazingly clear and sharp, even on cloudy nights.

The SkyWatcher 90mm refractor telescope is definitely enough for a beginner like me. SkyWatcher 3.5″ refractor telescope’s build quality is objective, though not the sturdiest. Lightweight and easy to carry around, which is nice. Lens is small but ample for viewing the moon, planets, and some deep-sky objects. Had minor issues with the focuser, but they’re barely noticeable. Altazimuth mount has smooth motion, making it easy to track objects in the night sky. Most telescopes in this range are often flimsy and lacking in quality, but the SkyWatcher 90-900 is a great exception.
