What does SCT mean in telescopes?
Schmidt Cassegrain Telescope
The Schmidt Cassegrain Telescope (SCT) design is the most versatile type of telescope available.
Do SCT telescopes need collimation?
Under normal use, you should be able to go months without collimating a telescope. Unlike collimating a Newtonian, there are no special tools required for an SCT. However, you will need to test the collimation on a star, so it must be clear and dark.

How often do you need to collimate an SCT?
if its just moving from say inside the house to outside. then really you shouldn’t need to collimate it maybe once ever 2-3 sessions. SCT’s and reflectors often need to be collimated.
How do I know if my SCT needs collimation?
You want to see a diffraction pattern of concentric circles appear around it. Basically, this refers to circles around the star that might look a little wiggly. If the circles you see are not concentric, then your telescope needs to be collimated.
How often should a SCT telescope be collimated?
What eyepiece comes with Celestron 8SE?
The Celestron NexStar 8SE computerized telescope comes with a single eyepiece – Celestron’s “E-Lux” 25mm Plossl – and a 1.25” star diagonal and visual back. The included 1.25” diagonal is a prism of very high quality.
Is Celestron 8SE worth it?
Optical Performance The optics in the NexStar 8SE are incredibly well made and provide brilliant image clarity and detail. They have Celestron’s own Starbright XLT coating for better light transmission and, as should be the case with a well-constructed compound scope, there are almost no noticeable aberrations.
Is the NexStar 8SE worth it?
Should I buy a Used Celestron NexStar 8SE? A used 8SE isn’t bad, and if you can get it at a low enough price (or as an optical tube only), it’s worth considering sticking it on a different mount such as a CG-5, Advanced VX, HEQ5, or Celestron’s beefier NexStar Evolution mount.
When did the Celestron NexStar 8SE come out?
1970
On the market since 1970, the Celestron NexStar 8SE is still holding its own.
Why is there a shortage of Celestron telescopes?
Celestron. “As more and more people are spending time at home and exploring the night sky we are experiencing a substantial increase in demand for our products. Additionally, the global shut down earlier this year affected our overseas suppliers and slowed the production of our products.
What can you see with an 8 inch telescope?
This size scope, however, is a bit small for deep-sky objects such as nebulae, star clusters, and galaxies. An 8-inch telescope (it doesn’t matter what type) will move you into a new dimension of viewing. The objects you see with an 8-inch scope will reveal more detail.
Why are all the telescopes sold out?
Explore Scientific. “In 2020, the entire worldwide telescope industry, including manufacturers and retailers, have seen an unexpected and unprecedented demand for products due to the COVID 19 pandemic and the media attention for Comet NEOWISE, causing some products to temporarily run out of stock.
What is the optimum magnification for an eight inch telescope?
As you get to 50x or 60x per inch of aperture, some faint extended deep space objects can become too dim to see. Thus, while an 8″ telescope is theoretically capable of a maximum useful deep space power of 480x (60 x 8), that much power is often usable only for splitting close binary stars.
What is the Celestron advanced VX?
The Advanced VX is the smallest of Celestron’s German equatorial mounts. The computerized GoTo capability automatically tracks objects as they move across the night sky. The Advanced VX mount includes ports for a hand control, an autoguider, and 2 AUX ports for optional accessories.
Where can I buy a Celestron switch for Nexstar 6se/8se telescopes?
You can buy a Celestron Switch, Power Jack, & Cables for NexStar 6SE/8SE Telescopes directly from High Point and replace the switch yourself – without needing to send it anywhere and pay for any expensive repairs. Owners of Celestron’s PowerSeeker 127EQ telescope love the ability to fine-tune the scope’s R.A. and declination.
What is a Celestron motor assembly and how does it work?
Celestron’s CGEM mounts have always proven to be popular, but if you find the motor isn’t working as well as it should, you can swap it out with a Celestron Motor Assembly. This motor and encoder assembly works with either the RA or Declination axis of the mount, making this a convenient, cost-effective solution.
How do you use a Celestron starsense telescope?
Just point the telescope at any three bright objects—stars, bright planets, or even the Moon—and your telescope can orient itself with the night sky. Celestron’s patented StarSense™ Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before.
