Product Description

This Astro-Tech 1.25" accessory kit includes ten 1.25" Astro-Tech visual accessories specially chosen to get the most out of small to medium size telescopes - from a 66mm refractor to an 8" to 9.25" catadioptric.

Unlike competitive kits that supply only a 50° apparent field Plössl for their medium focal length eyepiece, this Astro-Tech kit gives you a fully multicoated 1.25" four-element Astro-Tech 15mm SuperView eyepiece with an apparent field of view of 68°. It provides an exceptionally wide and dramatic field for observing nebulas, open star clusters, and galaxies. The Astro-Tech 15mm SuperView weighs 3.4 ounces and has a good 11mm of usable eye relief.

The Astro-Tech SuperView has a soft rolldown rubber eyecup to shield your eye from ambient light and improve contrast. It has dust covers for both ends of the eyepiece. Its chrome barrel is threaded for 1.25" filters, and a safety groove is machined into the barrel. This engages the thumbscrew or compression ring of your star diagonal to keep the eyepiece from falling in the dark should the thumbscrew accidentally loosen during use.

You also get three fully multicoated 1.25" four-element Astro-Tech Plössl eyepieces, in focal lengths of 4, 9, and 40mm. Like the SuperView, each has a soft rolldown rubber eyecup and dust covers for both ends of the eyepiece. Their chrome barrels are threaded for 1.25" filters, and a safety groove is machined into each barrel.

The 40mm Astro-Tech Plössl has an apparent field of view of 45°. It provides the widest field and brightest image possible from a 1.25" eyepiece with any scope down to an f/6 focal ratio. Competitive kits usually provide a 32mm eyepiece, which has a smaller exit pupil and is only about two-thirds as bright on faint objects as the 40mm in this Astro-Tech kit. The Astro-Tech 40mm Plössl weighs 5 ounces and has a long 18mm of usable eye relief, for virtually unvignetted views when wearing eyeglasses.

The 4mm and 9mm Astro-Tech Plössls each have a 52° apparent field. They are designed for high contrast/high power lunar and planetary observing, resolving globular clusters, and splitting close binary stars. Each weighs 1.5 ounces. The 6mm eyepiece has a short but still very usable 3mm eye relief, while the 9mm has a longer 6mm eye relief.

The supplied fully multicoated 2x Astro-Tech 1.25" achromatic Barlow effectively doubles the power of each eyepiece without reducing its eye relief. The 6mm effectively becomes a 3mm, while the 9mm becomes a 4.5mm. The 15mm SuperView effectively becomes a 7.5mm, while the 40mm effectively becomes a 20mm. The 25mm or 26mm eyepiece normally supplied as standard equipment with a new telescope effectively becomes a 12.5mm or 13mm when used with the Astro-Tech Barlow. Note that there is no duplication of magnifications with any of these eyepiece/Barlow combinations. The Astro-Tech Barlow weighs 2 ounces.

To bring out surface structure and details in lunar and planetary observing, you get the following four 1.25" eyepiece color filters: #12 medium yellow, #23A light red, #56 light green, and #82A blue.

You also get a 1.25" #ND-3 neutral density Moon filter to cut down the glare of our nearest celestial neighbor without affecting the color and increase the contrast of its features. The 50% light transmission filter is also useful for splitting close binary stars, as it will reduce the glare of the brighter star of the pair so that the dimmer component isn't overwhelmed by the light of the brighter one.

The Astro-Tech eyepiece bag is a soft-sided foam-fitted case for safely carrying your eyepiece collection as well as other accessories. You have a variety of cutouts that allows maximum flexibility. You can take pre-cut foam out to house a diagonal. There is also a piece cut out to hold a finder scope. Filter cutouts, 9 dedicated 1.25” cutouts, 3dedicated 2” cutouts, and 3 1.25’/2” cutouts give you so many choices as to what you can take with you in the field. Not only does it have great cutout foam, but it also has an exterior zipper pocket that runs the length of the bag. Inside that zipper pocket is four pouches and another zipper mesh pocket that runs the length of the bag as well.  The dense foam protects your eyepieces from shock and holds the case rigid.

The bag is an attractive medium gray nylon material, with a foam inner liner. The exterior bag dimensions are 20" L x 8.5" W x7" D. A carry handle and adjustable shoulder strap are included. This is a very well thought out eyepiece bag and should be in every astronomer’s arsenal.

I agree with the other reviewers that this is a great starter kit. With the exception of the barlow, everything is of good quality. A good way for the beginner to start. (Posted on 7/23/2019)

Major upgrade from the Tasco kit I had as a kid. I find I like the Possel 40 the best with my AT 6" RC, not really a visual scope but it works good at the FL. (Posted on 11/20/2018)

Great kit to get you started, the Astro Tech stuff is awesome for the price. I love the 15mm piece, and the case comes with plenty of room for goodies you may buy down the road (Posted on 10/16/2018)

I was quite surprised at how decent this set is, considering the price. Everything is of respectable quality, and the 15mm is really quite nice. The only reason it didn't get 5 stars from me is the Barlow, which is the weakest item of the set. Still, can't beat it for the price. (Posted on 8/4/2017)
