Celestron 94305 overview

  • 1Description

Celestron put together this 2" Eyepiece and Filter Kit for Schmidt-Cassegrain and refractor-style telescopes to give users the essentials for planetary observation. All of the accessories are made to fit and accept larger 2" accessories. This kit includes three Plossl eyepieces that provide a wide range of magnifications on any given telescope, five of the most popular colored planetary filters to enhance the views, and a 2x Barlow lens which essential doubles the magnification of any eyepiece used with it. This kit also includes a 90° star diagonal that puts the user's head in a comfortable viewing position when the scope is aimed high in the sky. The diagonal is outfitted with a standard SCT visual-back thread for easy direct-connection, plus an adapter to allow its use on refractor-style focuser drawtubes. An included hard aluminum carrying case protects the accessories while custom die-cut foam on the inside cushions them.

    Celestron 94305 reviews

    Eyepiece and Filter Kit (2") is rated 4.7 out of 5 by 7.
    Rated 5 out of 5 by from Very Nice Set! I purchased this set to go with my new Meade LX90 8 telescope. I have had the 1.25 set for many years, used with a Celestron Nexstar 4. Since the LX90 can use 2 lenses, it seemed natural to get this set. I have been very pleased with it so far. I've only had 2 opportunities to use it, due to the weather, but it performs admirably. Truly a very nice set of lenses and accessories! The increased field of view is outstanding! Viewing Jupiter again after so many years was awe-inspiring, as was M42. I can't wait to view the moon and Saturn with this set! A fantastic purchase, and it was delivered quickly, and free!

    Rated 4 out of 5 by from Bang for the Buck After a lifetime of using small (4) telescopes, we recently bought a used 10 Meade Schmidt-Cassegranian that came with two 1.25 eyepieces. We also had bought the Celestron zoom 8-24mm 1.25 eyepiece for the scope. The 2 eyepieces open up the view quite a bit, and the included 2x Barlow is useful for planets. The eyepieces are hefty, sturdy, and of high quality. It took a little experimenting to tighten the star diagonal properly on the back of the scope (the threads fit the Meade SCT). We have used the orange filter for the Moon, which improves contrast, and will experiment with the others in the future. We are very happy with the set, which comes in a sturdy foam-filled aluminum briefcase (additional storage areas in the foam would have been useful). One would have to pay much more if one bought these items separately.

    Rated 5 out of 5 by from A new dimension to a scope Moon is magnificent and the filters are just making it up to your expectations. Eyepieces are just huge in size. Rubber edge of eyepiece is very soft and take a wavy swollen look when taken out of the case.

    Rated 5 out of 5 by from Basic but high-quality set This is a great set for the price. I'm a beginner at astronomy, but I am extremely impressed with the build quality and the image quality of these pieces as a basic starter set. Highly recommended.
    Date published: 2016-06-27
    Rated 5 out of 5 by from Good value. Good starting point for 2 eyepieces. Good value to get you started on a 2 set of lenses, but will likely want to replace many of these with better optics over time.

    Rated 5 out of 5 by from Night and Day compared to 1.25 Awesome! Why didn't I buy these years ago?
