What is in the Celestron 94303 kit?

Five 1.25 inch Plossls (6, 8, 13, 17 and 32 mm), a 2x Barlow, six colour filters (#80A, #58, #56, #25, #21 and #12), a Moon filter and a foam-lined metal carry case: 14 accessories in all, by Celestron's count.

Is the First Light Optics "Eye-opener" kit the same kit?

Yes. First Light Optics sells it as the Celestron Eye-opener Eyepiece and Filter Kit, model 94303-CGL, with the same five Plossls, the 2x Barlow, the six colour filters and the Moon filter in an aluminium case.

Where can I buy the Celestron 94303 kit?

The prices I recorded: £239 at First Light Optics (UK), in stock; $240 at Agena Astro (US), in stock; $240 at Celestron (Global), listed.

What have I not tested on the 94303 kit?

I have not tested these Plossls against other eyepieces or measured their fields.

Stars for Your Buck 49/100

Written 25 Sep 2026 Updated 25 Sep 2026

Rank: #34 of 46 accessories
Verdict: With reservations

Written by Damon Scotting 2 min read

Buy it if

Your 1.25 inch telescope came with only one or two eyepieces
You want a spread of magnifications, a Barlow and filters in one case
You observe the Moon and planets visually

Skip it if

Your focuser takes 2 inch eyepieces and you want to use them
You want wide-field eyepieces: every Plossl here has a 52 degree field
You image with a camera rather than observe

49/100 Stars for Your Buck

Pros

Five Plossls: 6, 8, 13, 17 and 32 mm.
With the 2x Barlow, ten magnifications from five eyepieces, by Celestron's count.
Seven 1.25 inch filters: #80A blue, #58 green, #56 light green, #25 red, #21 orange, #12 yellow and a Moon filter.
Four-element, fully multi-coated eyepieces, all in a foam-lined metal carry case.

Cons

Every eyepiece has the same 52 degree apparent field.
1.25 inch only: nothing in the case fits a 2 inch focuser without an adapter.
The six colour filters are for planetary detail and the Moon filter for the Moon, in Celestron's own description: nothing in the case is for deep-sky nebulae.

The quickest way to fill an empty 1.25 inch eyepiece box, as long as Plossl fields are wide enough for you.
