Description

Eyes for the sky!

 

The Zhumell Telescope 1.25 Inch Eyepiece and Filter Kit is a great way to make the most of your telescope! Zhumell kits include a selection of eyepieces and filters that optimize available light. This, in turn, allows planetary features, galaxies, and binary systems to stand out in fine detail. All kits include fully-coated 1.25 Super Plossl eyepieces to ensure image clarity.

 

The Zhumell Telescope 1.25 Inch Eyepiece and Filter Kit is the perfect accessory for any scope!

  • 4mm high-grade eyepiece - 5mm Eye Relief, 50 Degree Apparent Field of View
  • 6mm high-grade eyepiece - 6mm Eye Relief, 50 Degree Apparent Field of View
  • 12.5mm high-grade eyepiece - 15mm Eye Relief, 50 Degree Apparent Field of View
  • 32mm high-grade eyepiece - 20mm Eye Relief, 52 Degree Apparent Field of View
  • 2x Achromatic Barlow Lens
  • #12 Yellow filter

  • #23A Light Red filter
  • #56 Green filter
  • #82A Light Blue filter
  • Polarizing filters
  • CrystalView Moon filter
  • Aluminum-sided eye-piece and filter case

 

Using Telescope Filters:

 

The Zhumell Astronomical Filters attach to the telescope side of the eyepiece barrels.   These filters will attach to any astronomical eyepiece with standard threading at the end of the barrel.  To use a filter, remove the eyepiece on which you would like to use the filter.  Looking at the end of the eyepiece which is inserted into the telescopes eyepiece receptacle, screw the desired filter clockwise into the eyepiece barrel.  To remove the filter, turn the filter counterclockwise.  Once the desired filter is attached to the eyepiece, insert the eyepiece into the telescopes eyepiece receptacle.

 

Some notes on Astronomial Filters

 

Astronomical filters work by blocking out certain colors in the visible spectrum of light.  A red filter, for example, will block out all but the red wavelength of light.  If you look at an object which is primarily red while using a red filter, the object will appear very bright.  Areas which are not red will appear more clearly because they contrast with the wavelength of light which is being passed by the filter.

 

When using filters, make note of the visible light transmission (VLT) of the filter you would like to use.  The VLT is a number which describes the overall amount of light which is allowed to pass through the filter.  The lower the VLT number, the dimmer an image will appear.  Filters with a VLT less than 40% are not recommended for use on telescopes with an aperture of less than 6" due to the decreased image brightness.

 

Filters are sorted by the Kodak Wratten numbering system.  Each filter is listed by its color and Wratten number.  The Wratten numbers help to ensure similar results between different filters.  The image should appear the same when viewed through any #82A Light Blue Filter for example.

 

#12 Yellow - 74% VLT

Yellow Filters help greatly in viewing Mars by bringing out the polar ice caps, enhancing blue clouds in the atmosphere, increasing contrast, and brightening desert regions.  Yellow also enhances red and orange features on Jupiter and Saturn and darkens the blue festoons near Jupiter's equator.

 

#21 Orange - 46% VLT

An orange filter helps increase contrast between light and dark areas, penetrates clouds, and assists in detecting dust storms on Mars.  Orange also helps to bring out the Great Red Spot and sharpen contrast on Jupiter.

 

#23A Light Red - 25% VLT

Light red filters help to make Mercury and Venus stand out from the blue sky when viewed during the day.  Used in large telescopes, light red sharpens boundaries and increases contrast on Mars, sharpens belt contrast on Jupiter, and brings out surface detail on Saturn.

 

#56 Light Green - 53% VLT

Light green enhances frost patches, surface fogs, and polar projections on Mars, the ring system on Saturn, belts on Jupiter and works as a great general purpose filter when viewing the Moon.

 

#82A Light Blue - 73% VLT

Light blue functions much the same as #80A Blue while maintaining overall image brightness.  Light blue will also help to increase structure detail when looking at galaxies.

 

Polarizing Filter

Polarizing filters are a great way to enhance astronomical viewing.  Compatible with any standard 1.25 inch format eyepiece, this filter will help to bring out contrast and definition in astronomical objects.  The polarizing filter reduces glare and is especially useful for viewing the moon.

 

CrystalView Moon Filter

A specific filter for lunar surface viewing.  The Moon can be so overwhelming to look at that much of the surface detail is washed away in light.  This filter dramatically increases the contrast and detail of the lunar surface.
