RECOMMENDED ACCESSORIES

Your telescope will need a star diagonal or erecting prism, eyepiece and mount in order to function. Since people have different preferences, we offer these separately. Here are our recommendations:

1. A star diagonal or an erecting prism.  If the telescope is  to be used for astronomy, use a  star diagonal such as our D1029ED or D1031ED. The D1029ED is a 2” diagonal that comes with a 1.25” adapter. It is the most flexible diagonal since either size eyepiece will work with it. If the telescope is used for  terrestrial viewing in the daytime, use an erecting prism such as our D1035 or D1032. The D1035 is a 2” unit with a 1.25” adapter making it the most flexible version to use.

2. Eyepiece. There are numerous types of eyepieces. Generally three or more eyepieces are used, one  for low power wide field viewing, a medium power for seeing more structure in deep sky objects and a high power eyepiece to view the planets and double stars. Please see Eyepiece Recommendations below. 

3. Mount and tripod. There are numerous types of mounts so  these items are offered separately. Please see Mount Recommendations below.

Eyepiece Recommendations

Low power: This is the magnification you will want for  locating objects or viewing large, star studded fields as you scan the Milky Way  viewing thousands of stars. Here are a number of choices based on optimal  performance in each price range:

A. Stellarvue E4032 32 mm Plossl eyepiece This is the least  expensive wide field eyepiece we offer. It is a 50 degree, 1.25" eyepiece. It  performs as well as any 32mm Plossl we have tested. Use this if you are purchasing a 1.25” star diagonal or erecting prism.

B. Stellarvue ESV30 eyepiece. The best 2" wide field  eyepiece in its price range. 68 degree field. Get a porthole view that is 20%  larger than the eyepiece above. This eyepiece will require a 2" Star  Diagonal or erecting prism.

C. Televue Nagler 22. This is the premium  recommendation offering superb correction across the field. It is an 82 degree 2" eyepiece. This eyepiece will require a 2" Star Diagonal.

Medium Power:  The Nagler 9 or 13 is recommended for this  telescope. It has an 82 degree field and is 1.25” so it will work with any star diagonal or erecting prism. If you decide to purchase the ESV30 above we suggest the Nagler 13 but if you select the Nagler 22 above we suggest the Nagler 9.  

High Power: For viewing details on the planets and splitting close double stars you must use high power.  Many inexpensive high power eyepieces have a very small eye lens making them difficult to use. Many also have very short eye relief so they cannot be used with glasses. We recommend our planetary eyepieces which have a large eye lens, 55 degree field of view, 20 mm of eye relief and a flat field. These are the eyepieces Vic uses to star test Stellarvue telescopes.

Mount Recommendations. There are  two types of mounts to consider for use with this telescope:

1. Grab and Go Alt Azimuth Mount. This type of mount is the  lightest and easiest to use. It is the most popular mount sold with this  telescope. The Stellarvue M1 or M2 Alt Azimuth Mounts are recommended as they are very smooth, stable and  easy to use. You simply slip the telescope into the dovetail shoe on the mount  and start observing. The M1 mount was designed for 70 - 80 mm telescopes. The M2 mount was designed for telescopes from 80 mm up to our SV115 It is superior to one arm fork  mounts since the telescope sits next to the center of gravity. This lessens  damping time considerably. Since this mount is so smooth, you simply glide  around the sky. Slow motion controls which are needed on rougher mounts are not  necessary. 

2. Equatorial Mounts: This is a heavier mount and it will  require some set up and alignment. We recommend two automated go-to mounts for  this telescope. The lighter and less expensive Celestron CG5 or the heavier and  more accurate Celestron CGEM. Both have computerized  go-to function and will track objects. Since these mounts are aligned with the  celestial pole, they may also be used for astro-photography. The CG5 mount may  be used with Stellarvue telescopes up to our 115. The CGEM can be used with  Stellarvue Telescopes up to and including our 130’s.
