94303 1.25" Eyepiece and Filter Kit by Celestron

• This 1.25" Eyepiece & Filter Kit includes fourteen (14) accessories that will add new life to your telescope and your observing!
• You'll get five quality Plossl eyepieces, a 2X Barlow Lens, six colored filters to improve observations of the planets, a Moon filter, and a foam-fitted aluminum carry case with extra room to grow.
• Five eyepieces and a Barlow lens equals ten different magnifications to choose from, including the equivalent of a 3mm, 4mm, 6mm, 6.5mm, 8mm, 8.5mm, 13mm, 16mm, 17mm and 32mm. And that doesn't include eyepieces you may already have in your collection, which will now achieve double the magnification with the addition of the Barlow.
• A Moon filter will increase your enjoyment of lunar observations by dimming the brightness and increasing contrast
• The most popular planetary filters are included in this kit. Have fun seeing what a blue filter will reveal about Jupiter, or unveil the polar ice caps on Mars with a red or orange filter.

The Celestron 1.25" Eyepiece and Filter Kit is a great way to expand the functionality and enjoyment of your telescope. Inside the metal, foam-lined carry case you'll find these accessories:

• 32 mm Plossl Eyepiece - 1.25"
• 17 mm Plossl Eyepiece - 1.25"
• 13 mm Plossl Eyepiece - 1.25"
• 8 mm Plossl Eyepiece - 1.25"
• 6 mm Plossl Eyepiece - 1.25"
• 2X Barlow Lens - 1.25"
• #80A Blue Filter - 1.25"
• #58A Green Filter - 1.25"

• #21 Orange Filter - 1.25"
• #12 Yellow Filter - 1.25"
• Moon Filter - 1.25"

2X Barlow Lens - The included, and very versatile 2X Barlow doubles the magnification of any 1.25" eyepiece. Since this kit includes five (5) eyepieces, you will be able to use them with and without the Barlow, giving you a total of ten magnification options in all. Any other 1.25" eyepieces you already have will also work in this desirable accessory, giving you even more magnification choices. Remember, high magnifications do not always produce clear, sharp results, especially on evenings of poor or moderate seeing conditions. Experiment to find the magnifications that are best for your telescope on a particular night.

Filters - Colored filters can be used to bring out certain details on a planet's surface or its cloud structure. All of the planetary filters included in the 1.25" Eyepiece & Accessory Kit, as well as the Moon filter, can be used on any 1.25" eyepiece with the proper filter threads, so they are very versatile. Just screw one onto your eyepiece of choice and slide it into the focuser.

The Moon filter is one of the first accessories most new amateur astronomers buy, and for good reason! It helps block out a portion of the light the Moon sends into your eyepiece so that you can see details better. You can also try this filter on Venus; it blocks enough glare so you can observe the planet's phases more easily.

Metal Case: The sturdy metal carry case has die-cut foam inside to protect and cushion your accessories. Store each one in its appointed place when not in use and you'll keep them looking and performing like new. The case is even large enough to carry a few extra accessories. Just pull out enough of the foam cubes to make a nest for your eyepiece, camera adapter, etc. A tight fit is better, so remove the least amount of foam possible before testing the fit. You can always remove more if you need to.

MA883BOX Digital Refractometer For Wine & Grape Juice / Must Measurments by Milwaukee

Thousands of food and beverage professionals and hobbyists, from chefs and food quality professionals to brewers and wine makers, have moved to digital Baume measurement from less accurate and less precise optical refractometers.

WHAT PEOPLE ARE SAYING

"Anyone who produces wine, grape juice, maple syrup or craft beer should find this product one of the best investments they make on any piece of equipment."

"I am in love with this instrument. No more large samples. No more phony readings from badly made refractometers."

"Dramatically improved my commercial brewing consistency & efficiency. Now I can quickly stop my sparge when I get to to my OG."

"I used this for finishing Maple Syrup. I had been trying to determine sugar content using temperature and a hydrometer. I found both very difficult to use. The refractometer was much easier."

"Very easy to measure the sugar in our must"

SUMMARY

The Milwaukee digital °Baumé refractometer is temperature compensated with a 0 to 28 Baume range and +/- 0.1 Baume accuracy. It is easy to use with simple two button operation and fast with a response time under 2 seconds. Maintenance is a breeze also with an easy-to-clean sealed flint glass prism and stainless steel well.
