1. Celestron 2-Inch XLT Diagonal Mirror (for SCT Telescope)
Feature
2" SCT mirror diagonal with high performance XLT coatings1/10th wave mirror is tested with an interferometer to ensure quality
Housing is precision machined to achieve and hold good optical alignment.
Includes a 2" to 1.25" adapter and aluminum carry case
Description
There are few telescope accessories that work as hard or matter as much as a diagonal! An integral part of the optical chain, a good diagonal can make a big difference in the quality of the image you see. A 2 diagonal is required if you want to use 2 eyepieces when observing with your telescope. The larger 2 barrel allows you to see a bigger percentage of the telescopes light cone, which works wonders for capturing faint deep sky objects with low surface brightness.The Celestron 2 Mirror Diagonal was built for superior performance. The housing is machined with precision instruments to make sure the optics stay perfectly aligned. The diagonals mirror is tested with an interferometer, and is guaranteed to be 1/10 wave or better. The mirrors surface is covered with the same high performance XLT coatings used on Celestrons best telescopes, and the result is a sharp, bright image that will satisfy the most discriminating amateur astronomer.
This 2 diagonal threads securely to the rear cell of standard Schmidt-Cassegrain telescopes. To take advantage of the XLT Diagonals extra light throughput, insert a 2 eyepiece into the barrel. If you want to use 1.25 eyepieces, slide the included 2 to 1.25 adapter into the eyepiece barrel and secure it with the thumbscrew. When youre not observing, store your diagonal in the included aluminum case for protection.

Description
he Celestron 2 Luminos Barlow Lens increases the magnification of your 2 and 1.25 eyepieces by 2.5x. The premium 4-element apochromatic optics are fully multi-coated for optimum light transmission and yield high contrast, true color images. The beautiful hard-anodized aluminum housing matches the eyepieces in the Celestron Luminos line. A centralized rubber grip helps to keep your hands securely on the barrel, even when your fingers are cold or you are wearing gloves. A brass compression ring just inside the top of the Luminos 2.5x Barlow grabs your 2 eyepieces gently but firmly when you turn the oversized thumbscrew. Once the thumbscrew has been secured in place, the brass ring keeps your eyepiece in the Barlow instead of relying on the tip of the thumbscrew itself, offering a better grip and protecting the barrel from scratches. A matching 2 to 1.25 adapter is included so that you can increase the magnification of all of your eyepieces, both 1.25 and 2, in this versatile Barlow lens. The insert barrel of the Celestron Luminos 2.5x Barlow is threaded to accept 2 filters. This is a nice feature, because you can change eyepieces without removing and reattaching the filter each time.5. Celestron Erect Image Prism for Refractor and Schmidt Cassegrain
Feature
A great accessory for daytime terrestrial viewing with your telescopeThis 1.25" diagonal produces right side up and left-to-right correct images when used with refractors and catadioptric (Schmidt-Cassegrain) telescopes
Inserts into 1.25" focusers or visual backs. Accepts standard 1.25" eyepieces
Description
Did you know that most telescopes work well for daytime viewing as well as for astronomy? If you have a refractor or a catadioptric telescope (the Schmidt-Cassegrain is the most popular example), and you would like to use it for terrestrial observations, the most useful additional accessory you can buy is an erect-image diagonal.If you look through your telescope with the standard mirror or star diagonal installed, you will notice that objects may be either upside down, flipped so that you see a mirror image, or a combination of the two. This is fine for observations of celestial objects, but it can be a little confusing when you are trying to track a boat as it moves through the water, or an eagle as he flies towards his perch.
Luckily, this is an easy problem to correct. Simply remove the standard diagonal from the telescopes focuser or visual back, and install the Celestron 45 Erect Image Diagonal. Now, when you insert an eyepiece, objects will be right side up and left-to-right correct. The 45 angle of this Amici prism diagonal is very comfortable for daytime observations, where the telescope is often in a horizontal position.
Please Note: Adding an erect-image diagonal to a Newtonian reflector will not result in images that are right side up and left-to-right correct. The optical design of a Newtonian will always produce images that are rotationally off in orientation. This does not mean that you cant use a Newtonian reflector during the day, it just means that you have to get used to objects oriented in unrealistic positions.
