Question about Optics
Posted by Anonymous on
With an aperture of 110 mm or so, the absolute largest useful magnification with this scope is about x 220 (certainly not 375 like thay say). However at this limit the image is dim, difficult to focus, and jumps around with any vibration. A more practical limit is about x 150 or so, which is attained with about a 4mm eyepiece.
I'd suggest 3 EPs in the range 5 - 30 mm. Alternatively buy 2 EPS and a x 2 Barlow Lens (This is a magnification multiplier, placed between the scope and EP, to double the magnification of that EP). A 10 mm Plossl EP and a 30-32 mm will give a good spread with the 2 x Barlow.
Even tho the scope is a budget model, a better lens will get the most out of it. . You will soon want a better one.

Do NOT use the barlow lens-- put the lowest magnification eyepiece into the scope-- practice focusing on the moon -- turn the focus knob slowly in and out until you get a sharp image.
Telescopes only show an area of sky about 1 degree wide or LESS--- this is about the size of the TIP of your finger held at arms length................ your scope is best used at low magnification.

The eyepieces have numbers written on them-- the bigger the number the LOWER the magnification. Start with the eyepiece with the BIGGEST number-- practice focusing the scope during the daytime on a distant object..,..... once you do.. switch eyepieces .... and see how much closer everything looks.
Try for the moon as your first target at night--- you can download a free star chart at www.skymaps.com

Sorry about Meade's responses, but their website has a download section for the telescope manuals - you may not find one that matches exactly, as they produce hundreds of models, but one that is close should suffice. As for eyepieces, there are several good vendors out there; Orion Telescopes, Meridian etc. Just check the barrel size; either .965" (Japanese standard) or 1.25" (American standard).

You will not find a manual. BUT you do not need one.
This is a very simple reflector telescope on an Equatorial mount. The mount must be polar aligned in order to properly use the scope. Read my TIP in my profile section about aligning an Equatorial mount.
The major steps are:
Align the small finder scope with the main telescope tube on a distant object.
Set the Declination axis to your Latitude.
Align the main tube with the axis of the mount.
Point the entire mount toward the North Star Polaris.
Use the fine RA & DEC knobs to center Polaris in the eyepiece.
See this web site and my tips--
This is why we NEVER recommend an EQ mount to a beginner. Polar Alignment just introduces one more FRUSTRATION to someone new to the Astronomy hobby.
The eyepieces simply go into the focuser. The Larger the number written on the eyepiece the LESS the magnification.
Take the scope outside during the daytime and practice focusing on a distant object using the eyepiece with the largest number.
The manual WILL NOT tell you how to find those small dim objects in the sky. It's just assembly instructions.It does not tell you how to become an amateur astronomer.
Locate a local Astronomy club and seek advice from the members, who will be glad to help you with your telescope.
