Question about Optics

1 Answer

We've just bought a 6'' Newtonian reflector and just can't see anything through it. We can see a vague ghostly disc during daylight, but at night it's totally blank. Is there something really basic we're missing out?

DO NOT use the 2x barlow if you have one. Inset the eyepiece with the largest number written on it and go outside during the daytime and practice focusing on a distant object.

If there is a local Astronomy club try to get one of the members to help you with the telescope. It could also be way out of collimation.

I need a Manual for National Geographic NG114AZ as well as replace the adjuster for the erecting eyepiece. where do I get these>


I think you are asking for a replacement focuser. You can probably find one here: http://www.ebay.com/itm/4-5-or-6-Telescope-Reflector-Tube-1-25-Newtonian-Focuser-Metal-Plastic-NEW-/360936594869?hash=item54097f5db5

A manual is another question. These scopes are imported and no manuals are available. However the manual only has assembly instructions it does not tell you how to use the telescope to find objects in the night sky.

Find a local Astronomy Club and the members will help you set it up-- very easy once you see it done 1 time.

Clear skies.

I just received as a gift, set it up and nowI am unable to see anything. the instruction manual is vague, only tells me how to set it up but not much else. thanks


The manuals DO NOT tell you how to find objects in the night sky, they are only assembly instructions. Wish you had not bought that telescope, this type would have been better for a beginner.

Take the scope outside during the day time and put the eyepiece with the largest number written on it into the focuser. Practice focusing on a distant object. The moon should be your first target at night.

Locate an Astronomy club nearby and the members will help you learn the sky. All sky objects are smaller than the tip of your finger held at arm's length. The scope must be pointed directly at them to see anything.

I am looking for a manual to download for a Spectrum 1 F900 astronomical reflector telescope I just inherited


I have never heard of that brand of telescope? However all newtonian reflectors work in a similar fashion.

You can download a Meade telescope manual at the web site below. Look under the REFLECTOR heading for one similar to your telescope.

Hi does anyone know anything about f1000114 sturnam short tube reflector telescope thankyou


Never heard of that brand. But all newtonian/reflector style telescopes work the same way.

Look around the Meade telescope manual web site for a reflector scope similar to your telescope.

Look under REFLECTORS-

Everything is upside down


Astronomical telescopes produce an upside-down and reversed image (image is rotated 180 degrees from an upright position) since this doesn't matter when you are looking at things in the night sky. Accessories are available for rotating the image to an upright position, but most of those accessories do not work well with Newtonian style reflector telescopes such as the 114EQ reflector.

Can't view anything at night.


It sounds like you have a Newtonian or Cassegrain reflector.  The black circle is the secondary mirror.  You need to insert an eyepiece into the focuser in order to properly use it.

Seben 150-1400 telescope


This is a pretty generic Chinese made 6" Newtonian reflector. The one's I have sampled produce excellent images. Celestron has a great online archieve of its manuals. This scope is similar to their C150-HD Newtonian Model #31056. The manual can be found here:
http://downloads.celestron.com/Manuals/telescopes/c150hd_g8n/c150hd_g8n_manual/c150hd_g8n_manual_0802.pdf

Google "beginning astronomy" and you'll get a quartr of million hits. Good over view here.

While you are there get a subscription to Sky and Telescope or their other publication aimed at beginners, Night Sky.

Find a local astronomy club and join it.
